GIScussions: Tales from Boston – the FOSS4G TGP

OSGeo Planet - Thu, 2017-09-28 10:17

This is my last post on the 2018 FOSS4G Travel Grant Programme (but you can look forward to several more about the 2019 TGP). I wanted to share some of the feedback that I have received from the TGP recipients.

In case you have forgotten, you can donate to the 2018 TGP now.

My name is Mayra Zurbarán, I am from Colombia (not Columbia!) and a PhD Student at Universidad del Norte in Barranquilla, Colombia in Computer Science. As a junior researcher in the area of location-based information systems, this conference is of great relevance.

In Colombia, however the Free and Open Source movement is present, but lacks strength. Thanks to the Sustain-T project by Erasmus Mundus I was privileged to do my doctoral internship at Politecnico di Milano with Prof. Maria Brovelli; member of OSGeo and a keen promoter of the Geo for All initiative. During this internship I was brainwashed of everything I thought were the right tools for my research and was introduced to the FOSS4G world, which I am proud to say I have contributed in a small part; developing the Hotspot Analysis Plugin for QGIS and now working on the second edition of the PostGIS Cookbook.Paul Ramsey’s talks definitely pushed some buttons on how the open-source economy works and why it is relevant to contribute!

My previous experiences with similar events goes back to attending the ISPRS conference 2016 in Prague thanks to the GeoLab, led by Prof. Brovelli. Since then, I was very interested of getting to attend a FOSS4G event and as this was my first! I was super enthusiastic to finally see what all the well founded fuss is about and if it were not for the awarded grant this would not have been possible. Thanks a lot to the organizing committee for taking the trouble to take on the immense task of pulling this awesome and necessary event through for the GIS community.

The possibility this conference brings for networking with people working on relevant and the most up-to-date developments was definitely the most valuable aspect of attending the conference; besides, the possibility of watching the contents online for the ones I wanted to be present, but were happening at the same time of the ones I did attend is a great plus; not just for me, but for everyone who was not able to physically attend.

Thanks again and rest assure you’ve set the bar high for upcoming FOSS4Gs. Mayra.

Anna Petrasova

I am a PhD student at North Carolina State University, where I am part of GeoForAll laboratory focusing on the design of dynamic geovisualizations and tangible interfaces for geospatial modeling. I participated in couple previous local FOSS4G conferences in the US and in Europe and always enjoyed them tremendously thanks to the relevant content and community.  FOSS4G 2017 in Boston was no different, it was a great experience from the start to the last day.

During the first two days of workshops at Harvard I delivered a workshop From GRASS GIS novice to power user and in the remaining time I helped attendees in two other workshops. I participated in couple workshops before and I know that there are times when you get confused, or something doesn’t work for you and without help it’s very difficult to catch up. So I was happy to help out in my colleagues’ workshops where they had over 40 people.

The first day of the main conference as a volunteer I helped direct people to the different presentation rooms. Additionally, at the OSGeo booth my colleagues and I setup an interactive demo of Tangible Landscape – a tangible user interface for geospatial modeling powered by GRASS GIS and Blender. It attracted a lot of folks to OSGeo booth and showed non-traditional and innovative ways to use OSGeo and other free and open source software in research and community outreach.

Later on that day I helped to record presentations, which is a great way to serve as a volunteer and at the same time get to see the talks. Since I work a lot with topography, I was glad to learn about new Arctic DEM and how it was created using open source tools, which I didn’t know before.

The following day I presented my work on Visualization and analysis of active transportation patterns derived from public webcams, where my colleagues and I used crowdsourced work to get information about pedestrians from crowdsourced webcams and visualize it with open source software. It was encouraging to see the room almost full and it made it easier for me to network with people later on. Networking was a big part of the conference for me, and there were many opportunities to make connections during the conference,  to ask about job situations, and to bring new people to my project’s community (GRASS GIS).

Since this semester I take class called Tools for Open Geospatial Science, I really looked forward to seeing Richard Stallman’s keynote, and I summarized it on the class dashboard and posted it for other students to help them understand the importance of user freedom and licenses.

Although Boston is a beautiful city, it is rather expensive and so this travel grant allowed me to stay during the entire conference. I was able to participate in the code sprint, and although this event is short, I was able to accomplish several small tasks on my GRASS GIS TODO list and at the same time get some new people involved in improving documentation and tutorials.

Back to Raleigh I am taking with me many nice memories, ideas, contacts, but also stickers and flyers, which I will distribute when there is opportunity.

Harison Andriambelo, University of Antananarivo-Madagascar The Open Source Geospatial Foundation kindly granted me a free registration for the FOSS4G 2017 meeting in Boston.  As a PhD student at the University of Antananarivo in Madagascar, this support was vital to allow me the oppportunity to participate in this conference. I regularly use free and open geospatial software in my work on wetland conservation.  It was great to learn about the latest developments in the tools I use such as spatial R packages and QGIS.  Across the parallel sessions I saw many inspiring talks on applications of geospatial technologies.  I was particularly interested in the new approaches for processing data collected from drones for environmental mapping, and in the diverse ways governments and NGOs are building environmental-related solutions using free software stacks.  Overall this was a great conference with some fascinating plenary speakers, very helpful exhibitors and a friendly atmosphere.  The gala event in the aquarium was a nice addition to the programme. Back in Madagascar, I am going to continue to explore using software that I learned about during the meeting, and I will share the potential of these tools with my colleagues.  I’m excited that FOSS4G 2018 wll be in Dar es Salaam.  Tanzania is much closer to Madagascar, so I hope to be able to attend again next year.

My name is Mohammed Zia.

I’m a PhD student and Geospatial Developer at one of the key GIS research and development centre at Istanbul Technical University, Turkey. I use FOSS4G and open-data for everything, whether it’s my research, a service developed for government and campus, or something else. Attending FOSS4G Boston 2017 was crucial for me, especially this year, for the following main reasons:

  1. It allowed me to connect, in-person, for the first time with like minded folks who believe in free-software and data movement. It was an overwhelming experience.
  2. It helped me to grow and learn as a team, since I was also in the Local Organising Committee.
  3. I met many potential employers where I had the opportunity to showcase and discuss my capabilities and skill-set.
  4. I met many great minds who helped me improve my understanding on many subjects.

All this would not have been possible without the financial support provided by the TGP. I was only able to cover a fraction of the whole expenditure, but TGP helped me cover the remaining part. I’m highly thankful to them and those sponsors who played crucial role behind the scene to help me, and many others like me, to attend this great event.

As I’m about to finish my PhD, with this newly built network, I’ll be able to move on to the next juncture of my career fairly easily. Meanwhile, being as the head of the GIS department of the lab, I’d encourage students to switch to the FOSS4G altogether and try to get involved with open-projects, not only in order to learn how to code better but also to make some solid contributions to a community that has always been so supportive and helpful in history. I believe that FOSS4G miss some educational part yet and there is a call for effort in that direction, although the current main focus is on software and data development and curation. I’m glad that being an academic person I was able to attend this event and now I’m thinking of connecting the dots in that direction.

I’ve attended many conferences in the past, but by far, this was the most successful and satisfying one. I’d love to get more involved with OSGeo activities in future with this new vigour and try to get more around gatherings like FOSS4G.

Thanks a ton TGP committee for letting me express myself and making my presence possible.


Jerome Oyetoro (abbreviated)

Generally, the FOSS4G conference 2017 in Boston was a success and an exciting experience. It was a gathering of about 1,139 Open Source enthusiasts, users and professionals from all over the globe who came to share their skills, experiences, interests and innovations in a two days workshop at the Harvard University and a three days conference at the World Trade Centre. The BLOC (Boston Local Organizing Committee) displayed a great level of coordination. The venues of the conference couldn’t have been better to host the number of attendees who graced the event.

eHealth Africa was duly represented with a presentation on “Using FOSS4G to Support Polio Eradication in West Africa”. Open Source for Geo Spatial is the way to go for the geospatial industry to reduce the cost of applications and foster collaboration and cooperation in solving the increasing challenges facing the world at this time from managing the sophistication of the mega cities in the western world to the poverty and health related issues in the developing world. I delivered a presentation on “Using FOSS4G to Support Polio Eradication in West Africa ” The presentation went well. The attendees in the presentation were excited about the great work eHealth Africa is doing on the polio eradication effort in Africa and are interested in our data. The presentation video was recorded and there was a promise to share the video at a later date.

Lesson learnt for me in the conference was huge and unquantifiable. I count myself as highly privileged to be given the opportunity to attend the conference. The hospitability of the people of the city of Boston was great, almost everyone I turned to for direction and guidance was willing to help, though a few were not. The conference organizers were very friendly and respond at the snap of the fingers to every request with smiles. This is for me a sense of belonging and breaking down racial barrier, disregarding cultural backgrounds and eliminating ideological differences to create a harmonious environment for the successful celebration of 2017 FOSS4G conference in Boston.

Most important is the increase in awareness in the need for collaboration, cooperation and contribution spirit that is required of everyone user and developer of the open source and free software for geospatial now and in the future. The shift from commercial applications in the industry is no doubt growing, even though, many GIS specialists still use the hybrid of the open source and proprietary applications.

I was shocked when I heard in the “Opening Planery” that $10,000 was what was initially available for grant, which then means there were only 10 recipients of $1,000 each plus granting access to the conference and the gala night which was another $850 in value. I counted myself lucky to have been considered for this philanthropic gesture by the good people of OSGeo. It went a long way to bring smiles and succor to me. Words are not enough to express my gratitude to Steven Feldman and Michael Smith for their flexibility, responsiveness, dedication, professionalism and hospitality. They handled everything with no fear or favor. They made it easy for the grant to reach everyone in the most convenient way demanded by the grantees.

I appreciate all the support given me from within and outside the organization from putting the presentation slides together, to fine tuning it, working through it, sharing ideas, contributing to it, to getting all the necessary travel documents together to making funds available without which the conference wouldn’t have been a success. The conference was a great experience for me and I do hope this would be sustained and most especially more attention would be given to Africa to build the community of OSGeo members. We are already building one in Nigeria https://wiki.osgeo.org/wiki/Nigeria, but needs a lot of support to drive some of our programmes targeted at contributing to the OSM through Mapathon and other programmes.

Preconference Workshop – Introduction to GIS Using QGIS

I attended an excellent preconference workshop at the Center for Geographic Analysis at Harvard presented by Frank Donnelly, the Geospatial Data Librarian at Baruch College CUNY. (http://2017.foss4g.org/workshop-signup/#openModal-301)

Participants were able to bring both the tools and the knowledge they gained from this workshop to enhance their projects and the organisations they work for. As the incoming IEB Geography moderator, this workshop has enabled me to used local data to produce maps for teacher resources and resources for the final geography Paper 2 examination.

The course content for this workshop was generously shared with us and Frank Donnelly has given me permission to distribute his course under the creative commons licence. I will be sharing this on the SAGTA website and at the 2018 IEB geography teacher’s conference: http://faculty.baruch.cuny.edu/geoportal/resources/practicum/gisprac_2017july_fd.pdf

Web-mapping is a growing trend and the GIS skills learnt will be transferred to material that I plan to develop in the classroom. St John’s College has run three GIS course for geography teachers to date and the new course material shared at this workshop will be used to update future courses. The workshop was also a wonderful networking opportunity. St John’s College will also be involved in a pilot programme to test GIS resources to teach earthquakes and tropical cyclones. http://scieds.com/gis-explorations-of-earth/ Once we have tested these resources, they will be shared at cluster, regional (ISASA schools) and hopefully at national level with other interested teachers.

The conference full schedule with keynote speakers and paper sessions can be found here: http://foss4g.guide. Fortunately, all presentations were recorded – frequently I wanted to attend two presentations at the same time. All the presentation slides were also made available: http://2017.foss4g.org/post_conference/ This is now a wonderful resource for teachers who were not able to attend. Talks can be viewed and slides used in the classroom as a teaching resource.

Last August 16-19, 2017, I attended the International Conference For FOSS4G held in Boston, Massachussets, USA. It is an annual recurring global event hosted by OSGeo. The FOSS4G (Free and Open-Source Software for Geospatial) conference is the largest global gathering focused on open source geospatial software. It brings together developers, users, decision-makers, and observers from a broad spectrum of organizations and fields of operation. I was one of the ten travel grant awardees under the OSGeo Travel Grant Programme (TGP). Through the financial support from OSGeoand UP NOAH have provided me, I was able to attend FOSS4G. It has given me the opportunity to gain knowledge on the on-going open-source projects around the world. My participation from the conference has provided me direct access to presentations from many organizations within the open-source community, allowing me to gain valuable information about what other projects are all about and where they are focusing their efforts. Attending this conference has provided me with opportunity to learn more about the latest free and open-source software for geospatial technologies and developments, but also increase visibility for the research organization I am working for, UP NOAH.

Favorite Sessions
  1. Breaking Up is Easy to Do: Leaving ESRI Behind for QGIS – A Case StudyThis, perhaps, was one of my favorite sessions. Alex Cohn discussed the reasons why their organization made a transition from using ArcGIS to QGIS and explained the impacts of this transition on their everyday operations for two years.
  2. It’s About People: Putting the ‘Community’ in ‘Open Data Community’This session was basically focused on solutions and challenges to empowering collaboration within the community using the MapStory project. MapStory is a free and open-source platform for crowd-sourcing global spaciotemporal data. Since it is a participation-focused open data platform, it emphasizes and revolves around the contribution of the global community.
  3. Lastly, I enjoyed listening to the talk of Steven Feldman about Fake Maps. Obviously, it was telling us about the power of maps that may mislead people through the message of the map intentionally, or through a lack of understanding. It was a fun and chill talk by Steven and I am sure that everyone loved it.
The Keynote

There were 5 keynotes for this year’s conference and I must say that one really stood out — the keynote from THE Richard Stallman. Dr. Richard Stallman launched the free software movement in 1983 and started the development of the GNU operating system in 1984. It is a free software — everyone has the freedom to copy it and redistribute it, with or without changes. It was a pretty long keynote though, but surely leaves discussion within the community about what an open-source software really is.

Wrap Up

Attending FOSS4G was quite rewarding for me. It is an opportunity that should not be missed. It was also great to meet the geo-geeks and learn so much from them.

I would want to take this chance to thank everyone involved in making this conference possible.

Next year, it will be held in Tanzania in August, and I hope to be there!

May the FOSS be with you!

gvSIG Team: Workshop at 13th International gvSIG Conference: Hydro-geomorphological Modelling in gvSIG with the JGrasstools plugins

OSGeo Planet - Wed, 2017-09-27 09:53

During the next 13th International gvSIG Conference there will be a workshop about “Hydro-geomorphological Modelling in gvSIG with the JGrasstools plugins” in English. It will take place in October 19th.


The climate change and the recent extreme events occured all over the world draw again the attention to the natural hazards both for prevention and for management aspects. In this context, environmental modelling can help in mapping hazards and risks zones and to support decision makers in building functional infrastructures with low environment impact.

In the context of modelling natural hazards hydro-geomorphology analysis is a key aspect. In the last decades many researchers tried to extract useful information from digital data and in particular from Digital Terrain Models (DTM) with the development of ad-hoc algorithms and tools. In the meanwhile the data availability increased and high precision DTM are available almost all over the world.

There are many possibilities to analise natural hazards and to define hazard and risks zones as required by the national and international directives. The algorithms contained in the JGrassTools library are the result of more than 10 years of research, development and real application of people from different research institutes and professionals working in the field of natural hazards. The JGrassTools library contains tools for data management (raster, vector and point cloud), data collection in the field, and environmental modelling in particular related to hillslope stability and flooding.

Target audience

The expected participant is the average GIS user that wants to approach new tools for environmental modelling related in particular to flooding hazard. The user can be a professional, a person of the public administration or even a decision maker who has average knowledge of GIS and GIS data and wants to approach this topic.

What will be shown?

The workshop will cover the main aspects of the hydro-geomorphological analysis of a river basin starting from a DTM. The aim is to evaluate the maximum discharge that can occur in a section for different return times following the rules of the EU Flood Directive. Some generic geomorphological analysis on the DTM will be performed that will be used to delineate the stream network and the watershed closed at the desired section, i.e. the flow directions, the total contributing areas and the slopes.

The last step will be the evaluation of the maximum discharges using the semi distributed model Peakflow (Rigon et al., 2011) integrated in the JGrassTools library.

Software and data

The last version of gvSIG will be used and the workshop will start with the installation of the JGrassTools plugins for all the participants both for the local available PC and for the private PC if there will be some.

During the next weeks the link to download the cartography will be available at this post for the participants that will carry their own laptop. The data will be loaded directly on the local PC.

How to subscribe?

To attend the workshop it is necessary to subscribe first to the conference and then to the workshop. All the workshops, as the rest of the conference, are free of charge, but the number of participants is limited.

The workshop will be at the Escuela Técnica Superior de Ingeniería Geodésica, Cartográfica y Topográfica (UPV), and there will be PC ready with software and data. If desired it is possible also to use private laptops.

The full program of the conference is available here:

Registration to the conference:

The registration to the workshops will open on the 28th of September through this link:

From GIS to Remote Sensing: Road to the Semi-Automatic Classification Plugin 6 (Greenbelt): the SCP dock

OSGeo Planet - Tue, 2017-09-26 16:37
As I wrote this post, QGIS 3 is under development and it should be released in December 2017.
This important QGIS update brings many new features; in particular, the upgrade to Python 3 and QT 5 imply that all the plugins must be updated to these changes.

I am updating the Semi-Automatic Classification Plugin (SCP) to version 6 (codename Greenbelt) which will work with QGIS 3 only (not QGIS 2 because of the API changes).
The codename Greenbelt (Maryland, USA) is the location of the NASA’s Goddard Space Flight Center that had a key role in Landsat satellite development and will lead the Landsat 9 development of the space and flight segments (Landsat 9 to be launched in 2020).

I have already released an SCP experimental version 5.99 that runs in QGIS 3. However, the QGIS 3 development is still going on and other API breaks could cause issues in SCP. Therefore, in order to focus on plugin development, I won't update the plugin repository until the feature freeze of QGIS 3.
The final SCP version 6 will probably be ready by December 2017, in line with the QGIS 3 release.

I am willing to improve the functionalities of SCP with this new version 6, and I'll try to periodically post the development progress.
First, I have updated the SCP dock in order to be more productive and user friendly.

gvSIG Team: Towards gvSIG 2.4: Heat map symbology

OSGeo Planet - Mon, 2017-09-25 11:35

In gvSIG Desktop 2.4 we are going to find legends that will increase, even more, the possibilities of information visualization of the application. One of these novelties is the heatmap legend, also known as hot spots.

The term means a place where there’s a high gathering of a feature. This type of legend is fundamental for certain analysis, for example in the criminology field to study the gathering of criminal incidents.

The customization possibilities of this new type of legend are very wide, allowing users to define distance, use a gradient or colour table, apply different range of transparency or use a weighting field.

Here you have a video where you can see how this new type of legend works:

gvSIG Team: Curso gratuito de Sistemas de Información Geográfica aplicados a Gestión Municipal: Temario y 1er módulo ‘Diferencias entre SIG y CAD’

OSGeo Planet - Mon, 2017-09-25 10:18

Lanzamos el primer módulo de un ambicioso curso gratuito para adquirir toda la formación necesaria para aplicar los Sistemas de Información Geográfica a la gestión municipal. Un curso basado en la utilización de la suite de productos gvSIG, un catálogo de soluciones en software libre para trabajar con la componente ‘Geo’ y que se compone de soluciones de escritorio, móvil y web.

Sobre el curso

El curso está basado en vídeo-tutoriales y ejercicios prácticos con datos municipales, con algunas y necesarias introducciones teóricas a algunos conceptos. Una vez realizado no dudamos que os convertiréis en unos expertos en el manejo de Sistemas de Información Geográfica y vuestro trabajo en la gestión municipal se verá consecuentemente optimizado.

El curso está destinado principalmente a técnicos municipales, ya sean arquitectos, delineantes, topógrafos, informáticos, forestales, ambientales,…pues casi cualquier área de un ayuntamiento trabaja de una u otra forma con información geoposicionada. Lo realmente importante es que pese a ser un curso muy completo y avanzado, comienza desde cero…por lo que no es necesario ningún conocimiento previo para realizarlo.

Esperamos que el esfuerzo y tiempo que hemos dedicado a su elaboración desde la Asociación gvSIG sea de vuestro interés y nos ayudéis a difundirlo lo máximo posible.

El temario del curso es el siguiente:

  • Introducción a los SIG: Diferencias entre SIG y CAD

  • Introducción a los Sistemas de Referencia

  • Vistas, capas, simbología, etiquetado

  • Tablas de atributos (información alfanumérica)

  • Introducción a las Infraestructuras de Datos Espaciales

  • Carga de servicios web desde gvSIG Desktop

  • Administrador de complementos

  • Edición: nuevas capas, edición gráfica y alfanumérica

  • Edición: geometrías derivadas

  • Geocodificación

  • Capa de eventos

  • Hiperenlace

  • Cómo pasar cartografía de un CAD a un SIG

  • Reproyección de capas vectoriales

  • Geoprocesamiento

  • Mapas

  • Georreferenciación de imágenes

  • gvSIG 3D

  • gvSIG Online: Publicación de cartografía

  • gvSIG Online: Edición, hiperenlace,…

  • gvSIG Mobile: Toma de datos en campo

Los 2 primeros vídeo-tutoriales son teóricos y a partir del módulo 3 pasan a ser eminentemente prácticos. En cada post (módulo) indicaremos el enlace a la cartografía necesaria para realizar los distintos ejercicios.

Para facilitar su localización todos los vídeo-tutoriales del curso se irán almacenando en una Lista de Reproducción.

Para cualquier tipo de duda o problema que tengáis, además, siempre podéis utilizar la Lista de Usuarios de gvSIG. En este post podéis encontrar más información sobre cómo inscribirse en la Lista: https://blog.gvsig.org/2015/06/15/que-hacer-cuando-sale-un-error-en-gvsig/

Por último, vamos a preparar una prueba final para todos aquellos que realicen el curso y quieran obtener un certificado oficial de usuario en gvSIG. Sobre la certificación daremos la información junto a los últimos módulos del curso.

Módulo 1: Diferencias entre SIG y CAD

En este primer módulo hacemos una introducción a los Sistemas de Información Geográfica, dedicando parte del mismo a identificar las diferencias entre SIG y CAD. Son muchos los ayuntamientos en los que se trabaja con CAD, pero pocos los que han implantado un SIG…veamos las ventajas de dar este paso.

gvSIG Team: Camino a gvSIG 2.4: Leyenda de mapa de calor

OSGeo Planet - Mon, 2017-09-25 05:51

En gvSIG Desktop 2.4 vamos a encontrar nuevas leyendas que aumentan, aún más, las posibilidades de visualización de información de la aplicación. Una de estas novedades es la leyenda de mapa de calor, también conocida por el término anglosajón de hot spots.

La traducción literal de ‘hot spot’ es ‘punto caliente’, el término hace referencia a un lugar donde existe alta concentración de un fenómeno. Un tipo de leyendas fundamentales para determinados análisis, como por ejemplo los que se dan en el ámbito de la criminología para estudiar la concentración de hechos delictivos.

Las posibilidades de personalización de este nuevo tipo de leyenda son muy amplias, permitiendo al usuario definir la distancia, usar un gradiente o tabla de color, aplicar distintos grados de transparencia o utilizar un campo de ponderación.

Os dejamos un vídeo en el que podéis ver en funcionamiento este nuevo tipo de leyendas:
