If you are interested in the use of GIS / spatial tools in the development and implementation of a management plan of conservation areas, have a look at Robert (GeoBob) Ford’s blog. It gives background information and ideas concerning the development of a GIS-based General Management Plan (GMP) for two national parks (Kundelungu and Upemba) in Congo. It is well written and clearly based on a lot of expertise. And for the visually inclined, there are a lot of very nice pictures too.
An announcement on the QGIS mailing list about NIWA Quantum map made me curious. How is this going to differ from QGIS? As it turns out, NIWA Quantum map is basically QGIS with a simplified interface, i.e., it has some GIS functionality hidden or removed to be less confusing for users not familiar with GIS. They used the customization options to disable the editing functions, so users can enable that if required. I wonder though why they did not do the same with the analytical functions, rather then removing it all together.
It furthermore has a custom plugin added to provide easy access to a number of data layers for New Zealand. As these are WMS or WFS data sources, you can of course open them in QGIS too, or any WMS or WFS compatible software for that matter.
I just came across an email thread on the QGIS email list that mentioned OSGeo-Live. This is a “self-contained bootable DVD, USB thumb drive or Virtual Machine based on Xubuntu, that allows you to try a wide variety of open source geospatial software without installing anything”. Worth exploring if you are looking for new great geospatial software.
In my previous post I explained how to add geometry values to the attribute table of a vector map in QGIS. You can do the same in GRASS GIS. It is slightly more complicated (don’t worry, it is still easy enough), but also more powerful. Below I will briefly explain how to use this tool using the GUI or command line. Continue reading →
What if you have a vector polygon layer and you want to add a column to the attribute table with the size (area) of each individual polygon? Very simple in QGIS, just go to the vector menu: vector | Geometry tools | Export/Add geometry columns, which will give you the following input screen: Continue reading →
