QGIS Plugins Repository

February 15, 2013 Sourcepole

The Region of Umbria, Italy, sponsored 4 days of work to update QGIS Globe for current QGIS versions. Most of the functionality is working again and the globe is now compatible with osgEarth 1.0 up to 1.3. The bad news is, that the globe plugin is not working on Windows with OSGeo4W. It seems that one of the OSGeo4W libraries (GDAL?) is compiled with an incompatible MS compiler version. Christmas holidays are coming…

At least it gives Linux users the possibility to play with the globe using the current development version and do exciting stuff like Oslandia does:

Imagine someone would sponsor four weeks of QGIS Globe work!

Creating 3D buildings from OpenStreetMap data

October 23, 2011 GFOSS

It is fairly easy to create 3D buildings from OpenStreetMap (OSM) maps, essentially by extruding the 2D footprint polygons to 3D.

For the procedure using OSGeo software, see

3D DXF from MapInfo Tab or ESRI Shape (or anything) using OGR

May 4, 2011 Nathans QGIS and GIS blog

Note:The following post requires gdal 1.8

A lot of times we need to send/use 3D dxf files, we used to use FME however FME is not free or cheap. So I went looking for a free solution.

If you have gdal 1.8 it’s just one simple command line run using, what is becoming my favorite GIS tool, ogr2ogr.

All you have to do is run:

ogr2ogr -f "DXF" {outFile} {inFile} -zfield {ColumnWithZValue}

So in my case I ran:

ogr2ogr -f "DXF" C:\Temp\contourswarwick.dxf C:\Temp\Contours.TAB -zfield Height

I haven’t fully tested it but {outfile} can be any file ogr supports.

and the output:

The side view of the above image.

In the words of, the not so great, Charlie Sheen. WINNING!

Happy mapping :D

Real World Mapping with the Kinect (via Decorator Pattern (Martin Szarski’s Blog))

January 25, 2011 Underdark

Always wanted your very own 3d scanner? Try Kinect:

Many people have experimented with using the Kinect for more than just user interaction. One thing that I have been very interested in is extracting point clouds from the device. People at the ROS (ros.org) project have gone to some trouble to determine empirical calibration parameters for the depth camera (disparity to real-world depth) here, and Nicolas Burrus has posted parameters for the RGB camera (relationship between the depth image and th … Read More

QGIS goes 3D

November 14, 2010 Sourcepole

Marco, Matthias and me spent three days at the QGIS hackfest in Wroclaw (pictures). There I got the time to work on the QGIS globe plugin and made a presentation of the current state.

As soon as the threading branch (Martin Dobias’ Google of Summer project) is merged into trunk, the globe should make its way into trunk as well. In the meantime you can compile the QGIS branch from guthub to test the globe. Thanks Vincent for writing step by step build instructions.
