If you work with raster data in GIS you straddle a kind of wierd world where you deal with imagery but you cannot really manipulate the imagery as you would say with the GIMP or Photoshop. Conversely, if you ever tried to open a large GIS raster dataset with the GIMP you may have noticed… Read more »
You know the drill right? You just made a beautiful map for your boss using QGIS Server. Then he walks into your office and says ‘Kiepie, I need another one in a different CRS’. Your heart drops in your chest and your jaw drops to the desk. You can’t do that using QGIS without publishing… Read more »
One of the most popular posts on my blog ever is my article about creating GDAL hillshades: ‘A workflow for creating beautiful relief shaded DEMS using GDAL‘. In the techniques outlined in the aforementioned article, colours are assigned across a continuum to and superimposed on top of a hillshaded model. The GDAL tools in QGIS… Read more »
Yesterday I wrote a new little plugin for QGIS. It is available here: http://plugins.qgis.org/plugins/VectorTransparency/ or if you prefer to get it from GIT then here: https://github.com/timlinux/VectorTransparency. You can also get the plugin by adding the new QGIS official repository (which will be available by default from QGIS 1.8 onwards) to your repository list: http://plugins.qgis.org/plugins/plugins.xml The plugin is very… Read more »
A nice article by Aslam Parker, Chief Directorate: National Geo-spatial Information, South Africa was published this month in our local GIS/Surveying magazine ‘Position IT‘ that describes the South African CRS. It probably would be of general interest to those trying to understand CRS concepts too. Direct link to the PDF here.
In two previous articles (one one using Eclipse to build QGIS, and the other on using Eclipse as a Django development platform), I mentioned I would delve a little into using the Eclipse environment as a platform for QGIS Plugin Development. In particular we are interested in using Eclipse as a remote debugging platform. What… Read more »
So we use the super awesome South to manage schema changes when we change our django models. Basically South works in the background to make sure that your database is always in a consistent state with your models. Recently I have been adding South to a project and deploying these updates to my server. One… Read more »
Eclipse is a Java IDE right? Wrong! You can use it for other languages too! I have been needing to improve my debugging techniques for python and Django (more on that in the future). This post outlines how you can set up Eclipse with PyDev to work on an existing Django aplication. The benifits? A… Read more »
Lex Berman from Harvard just dropped me a nice email with a link to an interactive QGIS tutorial he has created. The tutorial is one of the nicest I have seen – each section is detailed with text, screenshots and howto videos. I thought I would make a quick post about it here so the… Read more »
Everything I’m about to tell you you should probably forget – in my brief experience with it, Eclipse makes for an inferior alternative to Qt Creator if you are looking for a GUI to do development on QGIS with. That said, there are those for whom Eclipse is their weapon of choice. My primary motivation… Read more »
