Call for Papers: 5th International Workshop on Mobile Entity Localization and Tracking in GPS-less Environments

News Date: 
10 Jul 2015

5th International Workshop on Mobile Entity Localization and Tracking in GPS-less Environments
co-located with ACM SIGSPATIAL 2015
November 3, 2015 -- Seattle, Washington, USA

The mobile and sensing research communities have made remarkable progress in location sensing and activity detection in the recent years. However, many challenging problems still remain, including location and activity recognition accuracy, power management, effective sensor fusion, spatial environment representation, labor-less environmental surveys, crowd computing, and big data analytics of real-time and historical semantic locations and activities. We are soliciting papers and extended abstracts of up to four proceeding pages long. All contributions that deal with the scientific analysis of location and activity data sets are welcome. The papers for the workshop may include previously published or submitted work.

Workshop Scope:
The workshop specifically solicits research including but not limited to the following topics: Algorithms: Heterogeneous sensor data fusion for mapping and localization, probabilistic and statistical inferences, optimization, signal processing, and machine learning techniques for MELT problems, analysis of trade-offs of performance metrics (e.g. accuracy vs. time and cost), collaborative localization and mapping techniques, ad-hoc or opportunistic localization and mapping, efficient fingerprinting techniques, location data mining and prediction, location data acquisition and interpretation, energy-efficient localization and tracking methods, big data analytics, activity recognition using multi-modal sensor data, real-time and historical semantic localization;
Indoor map representations and automatic region or outline extractions, local and global maps and locations, geographical vs. topological maps, sparse vs. dense maps, map annotations, point of interest graphs, dynamic maps with real-time information, map markup languages or standardization, semantic location extraction and representation;
Localization systems on smartphones or mobile platforms, integrated with heterogeneous sensors (Wifi signal strength, inertial sensing, compass, odometry, etc.), efficient and accurate mapping systems using 2D or 3D cameras, active lighting or laser range finders;
User Interfaces:
Effective interface for entering and presenting maps and locations, notes or annotations for point of interests, innovative mechanisms for representing topological relations or maps with partial geographic information, efficient survey and mapping techniques;
Emergence personal localization, vehicular tracking in GPS-less areas, sports and entertainments, fleet management; asset, yard or inventory tracking, location-based recommendation or activity management.
Paper Submission Details:
Authors are invited to submit a short paper or an extended abstract up to four pages of new or previously published work. Manuscripts should be submitted in PDF format and formatted using the ACM camera-ready templates available at http://www.acm.org/sigs/pubs/proceed/template.html. All submissions will be refereed for quality and relevance by the Program Committee.

Submission URL: https://www.easychair.org/conferences/?conf=melt2015

The proceedings of the workshops are expected to be published jointly with the conference proceedings and will appear in the ACM Digital Library. One author per accepted workshop contribution (paper, poster, demo) is required to register for the workshop and the conference, as well as attend the workshop to present the accepted submission.

The OSGeo Conference Committee is happy to announce the call for hosting the FOSS4G 2017 event. Year after year, building on the success of previous conferences, excitement builds for the next FOSS4G! This year is no different with much excitement for Seoul, South Korea (http://2015.foss4g.org/). OSGeo again plans to make the 2017 event the geospatial conference of the year. Please see the following page for the actual request for proposals document, as well as upcoming important dates:


If you have any questions regarding the 2017 call for hosting, feel free to send an email to the conference-dev mailing list (subscribe at http://lists.osgeo.org/mailman/listinfo/conference_dev).

Thank you.

Open Source Geospatial Foundation (OSGeo) Develops a Code Of Conduct

News Date: 
29 May 2015

Over the last decade there has been a gradual adoption of Code-Of-Conduct statements at events and within organisations, including at FOSS4G events and within OSGeo projects. Adopting a good Code-Of-Conduct consolidates expectations about respectful behaviour at events and forums, ensuring they are safe, welcoming and productive and helps communities discreetly address indiscretions should they occur.

Building upon this initial momentum, the OSGeo Foundation has adopted a general Code-Of-Conduct to make it easy to apply to all OSGeo projects, and related events such as OSGeo.

Jeff McKenna, president of the OSGeo Foundation, explains:

"OSGeo community members must be able to safely interact, contribute, share, learn, and be respected for who they are. OSGeo strives to foster growth and innovation in the geospatial industry, and diversity must be respected to reach this goal. Thank you to everyone involved in creating this Code-Of-Conduct for the OSGeo foundation, and let us all continue to promote Open Source geospatial safely and fairly."

The Code-Of-Conduct can be referenced by adding a line similar to:

Contributors to this project are expected to act respectfully toward others in accordance with the OSGeo Code of Conduct.

The OSGeo Code-Of-Conduct is available at http://www.osgeo.org/code_of_conduct.

It is derived from the great work of other organisations, mostly from the Apache Foundation's Code-Of-Conduct.

About FOSS4G

Free and Open Source Software for Geospatial (FOSS4G) is the international gathering of Open Source geo tribes. From its beginnings the FOSS4G conference has a reputation of being a melting pot for great ideas in the spatial industry and a catalyst for many successful geospatial products, standards and protocols. FOSS4G has evolved into one of the most important geo events of the year, approaching a thousand attendees and with major industry sponsors. Excitement is now building for the upcoming FOSS4G2015 conference that will be held in Seoul, South Korea in September. FOSS4G rotates around the world each year, throughout 3 regions of the Americas, Europe, and Asia/South Pacific.

About OSGeo

The Open Source Geospatial Foundation (OSGeo) is a not-for-profit organisation founded in 2006 whose mission is to support and promote the collaborative development of open source geospatial technologies and data. OSGeo software and technologies are a major contributor for the global geospatial economy and are used by millions in academia, governments and businesses worldwide.
