Hei Jukka and Alberto, @Alberto: glad if you can keep working on it again. I will be around, but probably have not much time for coding. But I think I can promise that I am around for testing.
@Jukka: Density maps... basic functionality is there with Sextante, and I also programmed the HoRAE toolbox (Home Range Analysis and Estimation) that can create Density Maps with different types of methods. I thihnk what you are talking about in the example is actually the use of a the weight value. You can apply that too. So no need to create a new plugin ;) the toolbox and documentation is available here: http://sourceforge.net/userapps/mediawiki/mentaer/index.php?title=Movement_Analysis cheers, stefan Am 13.01.12 16:09, schrieb Alberto De Luca - GeA: > Jukka, > > - your first use case is a typical example of a plug-in that would be > possible to developed once a couple of the enhancement I proposed are > implemented (in particular: raster writing capabilities and improved > symbology managament); > - visualizing geotiffs with z-values would be also covered by improving > the symbology management. > > Alberto > > On 13/01/2012 15:41, Rahkonen Jukka wrote: >> Hi, >> >> I have two use cases in my mind, do you believe your work could help in >> solving these? >> >> - Create simple density maps (heatmaps) from point data.
