Generating Clickable Image Maps with Open Source Geospatial Software

Posted: January 7th, 2009, 8:21pm CET by Satri

Tags: opensource_community

Sometimes a common web search doesn't help you find what you're looking for, you have to ask the 'right persons'. I asked the OSGeo-Discuss list and learned that many open source geospatial software can generate html clickable image maps. Here's the summary of the findings: GRASS GIS, MapServer, GeoServer and QGIS. If you find more, don't hesitate to share it with the Slashgeo users below.

GeoWebCache 1.0 Released

Posted: December 16th, 2008, 2:05pm CET by Satri

Tags: opensource_community

arneke writes "GeoWebCache 1.0, a WMS tile cache implemented as a Java Servlet, has been released. The program is very fast, cached tiles are usually returned in milliseconds and hundreds of clients can be served simultaneously on even modest hardware. It supports services such as Google Earth, MS Virtual Earth and Google Maps. Requests that are not GetMap are forwarded to the backend, making it easy to use existing clients. It only needs a container like Apache Tomcat or Jetty and runs on any platform supported by Sun Java. It can easily be installed on Windows, Linux and Solaris. In addition to the usual bugfixes, this release includes a web front end that makes it easy to preview layers, seed the cache and reload the configuration. GeoWebCache supports two modes of configuration, you can either just provide a link to a WMS GetCapabilities document, or you can configure a layer in detail using an easy to grasp XML format. Multiple backends can be used for the same layer, they are queried in a round robin fashion with automatic failover. GeoWebCache is a community project closedly affiliated with GeoServer and licensed under LGPLv3. The software is maintained by OpenGeo, but has benefited greatly from contributions by individuals and organizations, ranging from bug reports to patches. It has also received genereous contributions through Google Summer of Code, namely the predecessor jTileCache by Chris Whitney, and REST and XML improvements by Marius Suta."

GDAL/OGR 1.6.0 Released

Posted: December 11th, 2008, 3:50pm CET by Satri

Tags: opensource_community

Major news, the almost ubiquitous GDAL/OGR library 1.6.0 has been released. Here's the official site. I dare repeat, GDAL/OGR is used by most open source geospatial projects, but also by many proprietary ones, like Google Earth and ESRI products. From the release notes, this is only the general highlights, because the list is very long: "General: * RFC 20: Preliminary support for alternate axis orientations in SRS. * On the fly access to data in .zip and .gz compressed files. * RFC 22: Support for reading from, and warping with RPC (Rational Polynomial Coefficients) from various formats. * Gaussian and Mode resampling added for overview generation. * Added raster to vector (polygon) conversion utility. * Added raster proximity utility. * Added raster sieve filtering utility. * Added -expand rgb/rgba ability to gdal_translate * Added cutline / blend support to gdalwarp. * Added -segmentize option to ogr2ogr to break long line segments. * RFC 23: Preliminary support for character set transcoding (in OGR for now). * RFC 21: OGR SQL supports type casting and field name aliasing" See also selected previous stories below.

GeoServer 1.7.0 Released

Posted: October 27th, 2008, 2:54pm CET by Satri

Tags: opensource_community

GeoServer 1.7.0 has been released. From the GeoServer blog: "Security in 1.7 has been improved by allowing access control at the layer/feature type level, in addition to the service level. This allows users to secure data in a much more granular way. There has also been much work done to better performance for GeoServer 1.7. The short of which is faster rendering with WMS, as well as faster data access with Shapefile, PostGIS, and ArcSDE. For those interested in the specifics check out the presentation given by Andrea Aime at FOSS4G this year in South Africa. Also of note for this release is a retrofit of the built in OpenLayers map preview. The preview interface now allows for filtering and controlling various rendering aspects such as anti-aliasing and image format. The folks from GeoSolutions have also been quite busy as usual and have once again made some great improvements on the raster/coverage side of things. GeoServer now supports additional raster formats such as ECW, MrSID, and JPEG 2000." Read the rest on the blog entry directly. See also related stories.

Open Source Geoprocessing: Boundary Generator 0.1

Posted: October 9th, 2008, 4:41pm CEST by Satri

Tags: opensource_community

Dan S. writes "I've spent a number of evenings over the last month putting together a small GPL geoprocessing tool for the ArcGIS platform; it's now at an alpha level of quality and suitable for early adopters to poke and prod. You can go straight to Boundary Generator, or read my initial announcement. It extracts the shared boundaries in a layer of polygons — a handy result for a number of purposes. Under the hood, you will find C# implementations of the underlying computational geometry as well as a simple quadtree spatial index. (I plan on writing a short series of blog posts about these components while I continue to refine Boundary Generator; they are the most interesting part of the project.)"

FOSS4G Wrap-Up

Posted: October 8th, 2008, 8:18pm CEST by Satri

Tags: opensource_community

Thanks to Directions Magazine who shares an Internet roundup of the FOSS4G event. There was surprisingly little geoblog coverage this year. From the OPP blog entry quoted in DM summary: "The result is a strange cultural mix. The FOSS crowd [is] lively, reliably laughing and applauding when a speaker makes a dig at proprietary software (PowerPoint, Internet Explorer, Apple). Their speeches are deliberately humorous and irreverent. After Ed Parsons gave a rather cluelessly untargeted talk about how Google's (proprietary) products are awesome and how easy it is for people to use them to make (proprietary) data, the crowd dragged him over the coals during the Q&A. The government and GIS groups must find this strange. Their tone was consistently more serious, more cautious, and less confrontational. The pace of their presentations was slower. They presented their tragic facts and their strategies to overcome them without the exuberance and confidence that this was their time to rally." You can read Ed Parsons reply here. You can read Paul Ramsey's entry on his Sol Katz Award.

An Overview on Current Free and Open Source Desktop GIS Developments

Posted: September 19th, 2008, 2:57pm CEST by Satri

Tags: opensource_community

Through an internal email, I got a link to this interesting and up-to-date research paper named "An Overview on Current Free and Open Source Desktop GIS Developments". The abstract: "Over the last few years the world of free and open source geospatial software has experienced some major changes. For instance, the website FreeGIS.org currently lists 330 GIS related projects. Besides the advent of new software projects and the growth of established projects, a new organisation known as the OSGeo Foundation has been established to offer a point of contact. This paper will give an overview on existing free and open source desktop GIS projects. To further the understanding of the open source software development we give a brief explanation of associated terms and introduce the two most established software license types: the General Public License (GPL) and the Lesser General Public License (LGPL). After laying out the organisational structures, we describe the different desktop GIS software projects in terms of their main characteristics. Two main tables summarise information on the projects and functionality of the currently available software versions. Finally, the advantages and disadvantages of open source software, with an emphasis on research and teaching, are discussed." Slashgeo regularly covers open source geospatial software, I copied below only a few of them.

GeoServer 1.6.5 Released!

Posted: September 17th, 2008, 8:10pm CEST by lxnyce

Tags: opensource_community

From the GeoServer blog : "The GeoServer team would like to present the newest stable version of GeoServer, 1.6.5. This is likely to be the last release of the 1.6.x branch, as development moves towards a stable version of 1.7.x. Nevertheless, this is an important release, as it features a whopping 65 bug fixes and improvements. Special thanks go to Léon van Berlo for translating GeoServer into Dutch. This marks our eighth language, and means we now have between approximately 100 and 6904 left to go, depending on what source we quote and how we define a language. We also have WMS point layers rendering correctly again, fixes regarding using the Google Maps projection, and improvements to the Map Preview area of the admin console. You can take a look at the entire changelog if you’d like, or just download this version and check it out for yourself."

Virtual Earth and StreetView Widgets in OpenLayers

Posted: September 3rd, 2008, 6:08pm CEST by Satri

Tags: opensource_community

I found no major news on the OpenLayers front since the 2.6 release last April, but these two Fuzzy Tolerance blog entries, published earlier this summer, explain how to include Microsoft Virtual Earth and Google StreetView widgets within OpenLayers. From the first entry: "With OpenLayers you can dump the standard VE or Google Maps tiles in your application, but the VE obliques are a bird of a different feather. Hence the need for a little widget rather than adding a VE layer to OpenLayers. I had seen the Google Maps and Virtual Earth Side by Side stuff before, but I couldn’t find a good tutorial on doing it with OpenLayers. I also only wanted a one way handshake - navigating on OpenLayers would navigate on VE, but you can pan/zoom VE without effecting OpenLayers. As it turns out, it so easy to do it’s almost silly. You can see the end result here (the VE map is behind the second “+” on the right)."

Tags: opensource_community

Camptocamp has developed a new Open Source project, it is called GeoAdminSuite . Their main objective is to improve the management of geospatial data coming from heterogeneous sources (local files, databases located on different computers). GeoAdminSuite version 0.9 is composed of 4 logical parts: server selector, catalog, composer and publisher. GeoAdminSuite (based on Java technologies) uses three Open Source components: MapServer as web-mapping server, MapFish as web-mapping application and Geotools as geospatial data manager. The goal of this publication is to get feedback from developers and users to see if this project is interested for the open source geospatial community.

Doing ESRI-like GIS with Open Source GIS?

Posted: April 30th, 2008, 10:37pm CEST by Satri

Tags: opensource_community

Spatially Adjusted links to an interesting discussion over the OSGeo-Discuss mailing list about open source careers and whether open source GIS software are up to par vs commercial GIS [Nabble link]. SA picks an insightful quote from Paul Ramsey, formerly of the Refractions fame: "My general synopsis: for server-side, for scriptability, for automation, for web-based, open source wins for most use cases, given a technically savvy user; for ad hoc, for cartographic production, for a user who is used to a point-n-click experience end to end, proprietary still wins." Slashgeo regularly covers open source geospatial software. I copied some previous related stories below. With 52 North, the OSGeo and all the open source geospatial software such as the widely used GDAL, we can say open source geospatial software is in a healthy situation. Note that we also cover commercial geospatial software, including from ESRI. Editor's note: I usually read the OSGeo list myself and share interesting bits with our users, since I've been away from office, expect more thorough coverage after the summer. Meanwhile, there's always submissions.

Using OGR to Visualize Data

Posted: January 23rd, 2008, 12:12am CET by Satri

Tags: opensource_community

Spatially Adjusted late in December discussed a simple yet revealing example of using OGR to visualize data. From SA: "Take GDAL/OGR for example, the webpage probably scares off most users because of the lack of examples of how to use both toolsets. But the tools themselves are so easy to use this shouldn’t scare anyone off. [...] That said Tom Kralidis has a great example of using OGR to convert a Microsoft Excel file to KML. GDAL/OGR is integral to so many GIS applications (even ESRI uses it) that any GIS professional should have at least a basic understanding to how it works." GDAL/OGR 1.5.0 was released late last year and see also this story when OpenLayers revealed itself as a data converter and an example of using a one OGR command to publish a point shapefile to html.

Building a Geoportal with Open Source Software

Posted: January 15th, 2008, 5:41am CET by Satri

Tags: opensource_community

Late last December the Fuzzy Tolerance blog ran a nice demonstration of building a geoportal with open source software such as OpenLayers, TileCache, GeoServer, PostGIS, jQuery, REST and AJAX. Here's the resulting geospatial portal. From the blog: "From a developer’s perspective, the biggest advantages I’ve found with OpenLayers-Tilecache-jQuery-REST is speed and simplicity. The beta site went from an empty text file to release in only a few weeks of actual development time nestled in between other projects, with a lot of that taken up by a jQuery/OpenLayers/GeoServer/SLD learning curve, design, web service work, software setup, etc. It is also marvelously simple, being nothing more than Javascript and HTML. From an end-user perspective, you get a much more responsive application, a nicer map interface than I usually give people via OpenLayers, and everything is free and open source." I copied below some of the previous Slashgeo stories regarding the software used in the demonstration.

The problems fixed in this distribution can be checked from the Release Notes Section and to install the partial update you must have gvSIG 1.1 correctly installed. On the other hand, the pilot application awarded the development contract for the 3D Extension by the Regional Ministry of Infrastructure and Transport is available too. It allows the creation of 3D Views, XYZ-projected as well as spherical (planetary), where local and remote data sources can be loaded as layers, and displayed using most of the options available in 2D like transparency, labeling, legends, etc. It's available in the Extensions section of the web page and to install this extension you must have correctly installed gvSIG 1.1.1 version."
