Boundless Blog: Creating a custom build of OpenLayers 3 (Revisited)

OSGeo Planet - Wed, 2014-10-29 13:53
pa href=http://openlayers.org/img alt=OpenLayers class=alignright size-full wp-image-5736 height=138 src=http://boundlessgeo.com/wp-content/uploads/2013/09/OpenLayers_Icon.png style=margin-left: 10px; width=137 //aSince a href=http://openlayers.org/OpenLayers 3/a likely includes more than needed for any single application, we a href=http://boundlessgeo.com/2014/02/openlayers-3-custom-builds/previously described/a how to generate custom builds with just the relevant code./p pAs promised back in February, things have changed for the better and it’s now easier than ever to create a custom build of OpenLayers 3 thanks to a task called codebuild.js/code that uses a JSON configuration file. Documentation for the tool resides a href=https://github.com/openlayers/ol3/tree/master/taskshere/a./p h2Configuration file/h2 pWe will now use build.js to create a custom build for the GeoServer OpenLayers 3 preview application, the same application that we used in a href=http://boundlessgeo.com/2014/02/openlayers-3-custom-builds/our previous blog post/a. The full configuration file for our application can be found a href=https://raw.githubusercontent.com/bartvde/geoserver-ol3-preview/master/geoserver.jsonhere/a./p pThe codeexports/code section of the configuration file defines which parts of the API will be exported in our custom build. By using the name of a class such as codeol.Map/code we export the constructor. By using a syntax such as codeol.Map#updateSize/code we are exporting the updateSize method of codeol.Map/code. The codeexports/code section is basically the replacement for the a href=https://github.com/bartvde/geoserver-ol3-preview/blob/master/geoserver-preview.jsexports file/a that we used in the older blog post./p pWe did not make any changes to the codecompile/code section. In the codedefine/code section we are using the same defines as we were using before with Plovr, but its syntax is a bit different codeol.ENABLE_DOM=false/code versus codeol.ENABLE_DOM: false/code. By the way, OpenLayers 3 does not use Plovr anymore./p h2Compiling/h2 pTo compile our custom build, first make sure you have run codenpm install/code in your OpenLayers 3 git clone directory, then use the following command:/p pcodenode tasks/build.js geoserver.json ol.min.js/code/p pThe first argument (codegeoserver.json/code) is our build configuration file, the second argument is the name of the output file./p h2That’s it!/h2 pThe end result should be a much smaller file tailored specifically to the needs of this specific application./p pemInterested in using a href=http://boundlessgeo.com/solutions/solutions-software/openlayers/OpenLayers/a in your enterprise?

Boundless Blog: QGIS Compared: Cartography

OSGeo Planet - Tue, 2014-10-28 13:56
p dir=ltrimg alt=Gretchen Peterson class=alignright size-full wp-image-9187 height=138 src=http://boundlessgeo.com/wp-content/uploads/2014/03/Gretchen1.png style=margin-left: 10px; width=138 /As mentioned in my a href=http://boundlessgeo.com/2014/10/qgis-compared-p1-visualization/previous post about visualization/a, QGIS is a href=http://boundlessgeo.com/solutions/solutions-software/qgis/easy-to-install/a, a href=http://boundlessgeo.com/2013/11/opengeo-suite-and-qgis/integrates with OpenGeo Suite/a, and has reliable a href=http://boundlessgeo.com/2014/09/announcing-qgis-support/support offerings/a, making it a viable alternative to proprietary desktop GIS software such as Esri ArcGIS for Desktop. I’ve written a href=http://gretchenpeterson.com/cartographers-toolkit.phpa couple/a a href=http://gretchenpeterson.com/gis-cartography.phpof books/a on designing cartographic products so it is something I’m passionate about and it is definitely an important component of desktop GIS. So how does QGIS perform when it comes to cartographic design?/p p dir=ltrIn making the examples for this blog post series, I was impressed by the capabilities of QGIS and found it was easy and straightforward to create maps like the Halloween map below./p h3 dir=ltra href=http://boundlessgeo.com/wp-content/uploads/2014/10/HalloweenFortCollins2014.jpegimg alt=Halloween in Fort Collins, 2014 class=alignnone wp-image-10962 height=372 src=http://boundlessgeo.com/wp-content/uploads/2014/10/HalloweenFortCollins2014-1024x662.jpeg width=576 //a/h3 h3 dir=ltrStrength: Text and Image Elements/h3 p dir=ltrPlacing text and images is as easy as finding the emAdd new label/em and emAdd image/em buttons on the left-hand side of the print composer (a). Once you add a text box or any other element, the Item properties tab on the right-hand side of the print composer gives you most of the complex options that you’d find in any layout or commercial GIS software such as alignment, display, and rotation (b). You can also align these elements by using the emAlign selected items/em button in the main button bar (c)./p p dir=ltrimg alt=composeritems.png height=403px; src=https://lh6.googleusercontent.com/SsrD2dvDW47o13u7PFSGefkw3shuG9wrizmpcyH7cw3hqaWd-1bs6te11lGlzSSjFshrZ7_k77O5j2NKPfQ0-ZSd3jN1x1hlxjvPK5fIWY2CJ9a8p8efPG498saYDmBiGQ width=624px; //p h3 dir=ltrStrength: Advanced Techniques/h3 p dir=ltrAdvanced labeling functionality is included in the main QGIS interface, including SQL-based labeling, font choice, and placement protocols. Exporting a layout to SVG for editing in a href=http://www.inkscape.org/en/Inkscape/a or other design software is easy. Another advanced technique is the creation of atlases, or map books, that replicate a layout for each part of an indexed main map. QGIS provides an atlas composer as part of the core functionality within the emPrint Composer/em, a very powerful feature./p h3 dir=ltrStrength: Color Blending/h3 p dir=ltrAn exciting feature is the addition of color blending modes, typically found only in design software, that can add special effects to the look and feel of the map by adding texture or special brightening effects, for example. The following modes are available: lighten, screen, dodge, addition, darken, multiply, burn, overlay, soft light, hard light, difference, and subtract. Color blending can be applied to a single layer in the layer properties dialog (a) or it can be applied to an entire map in the Print Composer (b)./p p dir=ltrimg alt=texturemaps.png height=281px; src=https://lh5.googleusercontent.com/__S-xHLtZLoPbBquJNZfGHcHkvqnyM8rHky18pKL-nXntEc1xeQYAu88_yAz_zYvyGerQTXCXcl9VjGfyGyY8si2tfsiXt4xbt5D7jkiiPxfHe8Y7xU6IxOc1iB1ZQlG1A width=624px; //p h3Mixed Results: Map Elements/h3 p dir=ltrAdding the map to the layout is a little more difficult if you are used to commercial GIS software. You have to use the emAdd new map/em button (the wording of which I found to be confusing since it somehow implies a new map rather than the existing map in your project), which adds the map from the main QGIS project to the layout. Another potential area of confusion is the fact that once the map element is added to the project, it doesn’t dynamically update if the main map is changed. In fact, to update it there are actually two buttons in the map element’s emItem/em properties: one to update the preview and the other to set the map extent. The former updates the map if a new map layer has been added or the symbology has changed but only the latter updates the map if it has been panned or zoomed. These, however, are minor quibbles./p h3 dir=ltrMixed Results: Sizing and Graticules/h3 p dir=ltrThe emPrint Composer/em does have a few shortcomings that I suspect will be cleaned up in later releases. It isn’t possible to change the size of multiple images all at once. For example, enlarging the pumpkin images in the right-hand information panel of the example map has to be done for each pumpkin separately since selecting them all and changing the properties isn’t possible. Also, there is no graticule functionality in the emPrint Composer/em. Instead, the user would need to find or create a graticule line dataset to add as a layer in the map if a graphic-like grid was desired. Another minor quibble is that the size dialog for images has the wrong tab order (if you try to tab between the input boxes the tabbing skips boxes instead of sequentially moving the cursor to the next input box)./p h3 dir=ltrHidden Gem: Gradient Fills/h3 p dir=ltrGradient fills, also known as vignette effects, are also possible, in a new plugin called a href=http://planet.qgis.org/planet/tag/shapeburst/Shapeburst/a. You can use it to achieve subtle shading along land-water boundaries but also to do some unexpected things like banding the edges of administrative boundaries in different colors or to reverse-fade the edges of a map. This latter effect takes advantage of QGIS’s built-in inverted polygons tool, which simplifies what used to be a task that would take several steps to achieve./p h3 dir=ltrConclusion/h3 p dir=ltrThe cartographic capabilities of QGIS are sufficient to produce almost all the common map layout components with an adequate amount of advanced capabilities and even some options, like the color blending modes, that aren’t typically found elsewhere. Cartography is where many people think that QGIS falls short. However, in making the examples for this blog post series, including the Halloween map, I was blown away by its capabilities. See also the a href=https://www.flickr.com/groups/qgis/QGIS Map Gallery/a for more map examples. Overall, my experience with QGIS has been that the a href=http://boundlessgeo.com/2014/10/qgis-compared-p1-visualization/visualization/a and cartography functions of QGIS have matured to the point where GIS professionals of all types can’t afford not to strongly consider adopting it.span style=font-size: 13px; /span/p pThe post a href=http://boundlessgeo.com/2014/10/qgis-compared-p2-cartography/QGIS Compared: Cartography/a appeared first on a href=http://boundlessgeo.comBoundless/a./p

Tyler Mitchell: Spatialguru change on Twitter/Google Plus accounts

OSGeo Planet - Sun, 2014-10-26 06:45
pAs a result of moving slightly away from “spatial” as a core focal area in my day-to-day work at a href=http://www.actian.com target=_blank title=Actian.comActian.com/a – (I do way more with Hadoop than spatial these days),  I started a new Twitter account with a less domain specific name./p pMy original Twitter account was a href=https://twitter.com/spatialguru target=_blank title=Old twitter account - spatialguruspatialguru/a – I still use it, but less often than before . Now I’m using a href=https://twitter.com/1tylermitchell target=_blank title=New twitter account - 1tylermitchell1tylermitchell/a instead./p pWhen I started calling myself emspatialguru/em it was a bit of an inside joke around our home, I didn’t think it would still around this long.  img alt=:) class=wp-smiley src=http://www.spatialguru.com/wp-includes/images/smilies/icon_smile.gif / Anyway, follow my a href=https://twitter.com/1tylermitchell target=_blanknew account/a if you want to see more about what I’m reading, etc./p pSimilarly, I have tried to migrate my previous Google plus account – tmitchell.osgeo – to a href=https://plus.google.com/u/0/102244282944340468041/ target=_blank title=New Google Plus accounta new one here/a.  Add me to your circles and I’ll probably add you to mine if you aren’t already./p pNow, what to do about this blog name.. hmm.. more to come./p p style=text-align: right;– Tyler/p

pThough the kindness of everyone we made it to over a href=https://www.mycause.com.au/page/79669/eloises1stbirthdayheartfelt$2000/a to donate two, not one like we had planned at the start, camera packs to hospitals that need them. One will be going to the new Gold Coast hospital where Ellie was born and the other to another hospital who needs it. Both cameras will have Ellie's name on them in her memory. They will go a long way to help preserve the memories of those last minutes just like it did for us with Ellie. /p pThe money is now with Heartfelt and hopefully the cameras will be done soon. I will update this post with photos once they are done./p pIt was really amazing to see the number of people who I have never meet in person from all over the internet throwing in what they could to help us reach the goal.

p15 октября a href=http://blog.revolutionanalytics.com/2014/10/introducing-revolution-r-open-and-revolution-r-plus.htmlвышел Revolution R Open/a — версия a href=http://cran.r-project.org/языка R/a от a href=http://projects.revolutionanalytics.com/Revolution Analytics/a, многие годы выпускающих коммерческую версию R, имеющую «встроенную» многопоточночть. Revolution R Open emобладает улучшенной производительностью/em по сравнению со стандартной версией R за счёт использования Intel Math Kernel Libraries (MKL) вместо стандартного R BLAS/LAPACK (при этом не требуется каких-либо дополнительных модификаций вашего кода); полностью совместим с приложениями, пакетами и скриптами, работающими с R 3.1.1; распространяется под лицензией GPLv2./p pRevolution R Open a href=http://mran.revolutionanalytics.com/download/доступен для скачивания/a для следующих платформ:/p liUbuntu 12.04, 14.04/li liCentOS / Red Hat Enterprise Linux 5.8, 6.5, 7.0/li liOS X Mavericks (10.9)/li liWindows® 7.0 (SP 1), 8.0, 8.1, Windows Server® 2008 R2 (SP1) and 2012/li pbr / Так же имеется экспериментальная поддержка для:/p liOpenSUSE 13.1 (обновлённая сборка Revolution R Open для OpenSUSE от 18 октября у меня работает хорошо)/li li OS X Yosemite (10.10)/li pbr / a href=http://www.revolutionanalytics.com/revolution-revor-enterprise-benchmark-detailsЗдесь/a можно посмотреть сравнительные тесты (с воспроизводимым кодом) стандартного R и R от Revolution Analytics./p pВ частности, у меня такие результаты теста умножения матриц для Revolution R Open:/p pregt; set.seed (1) gt; m lt;- 10000 gt; n lt;- 5000 gt; A lt;- matrix (runif (m*n),m,n) gt; system.time (B lt;- crossprod(A)) user system elapsed 14.690 0.141 3.856/pre pВесьма неплохо! Однако не следует ожидать существенного прироста производительности сторонних пакетов. Я, например, тестировал spatstat: как использовалось только одно ядро, так и используется. Может с другими пакетами повезёт больше )))/p
