Hi, I use qgis for my thesis at school. The thesis is about a castor fiber and its presence in some area. My advisor use ArcGIS and, I suppose, a plugin called Kernel density estimation, which helps analyze the data we have. You might say, why don't I get ArcGIS? The answer is simple, I am a student and don't have enough funds for it and also would like to do it on open source software. So I came across SDA4PP plugin to qgis and was pretty excited, though initial excitement faded out after realising quite complex installation process. Well, after some time I realised there is also a installer taht contains all dependancies and qgis 1.4.0. So there's a first question: can I use the plugin not only with 1.4.0 qgis, but also in 1.6.0 (my current one) or even in 1.7.0?
The second problem, more important: I have point data in form of .gpx file (points with coords). When I open it as a vector layer in qgis (waypoints) and try to run "Kernel density" (part of plugin) or any other like "Uniform density", "Adaptive density" which I have no idea whate they do, I get the same result. *The error message:* An error occured: Error in ogrInfo(dsn = dsn, layer = layer, input_field_name_encoding = input_field_name_encoding) : Cannot open layer Though now when I'm trying to solve the problem I'm not getting the same errors as yesterday (some coding related stuff), still it's not working. Yesterday there where also some ANSI problem. So I tried to change it (Mapsource I use to manage .gpx files doesnt have an option to choose coding of a text in it (ANSI, Unicode,...), notepad has (but opens .csv not .gpx). But after opening the same stuff, only .csv in notepad I found it's coded in ANSI. And qgis doesnt open .csv files. So although I have no experience in using that plugin (and honestly not much in any way), I cannot even run the plugin properly. SDA4PP version 0.196 If anyone has an idea to solve this problem and help me out, I would appreciate it. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/SDA4PP-Kernel-density-troubleshooting-tp6621793p6621793.html Sent from the qgis-developer mailing list archive at Nabble.com. _______________________________________________ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
