Hello:
I'm trying to create some density maps using the Arun's heatmap plugin, in
QGIS 2.2 Valmiera on Ubuntu 14.04.
When I use a large sample data from a tutorial everything works fine.
(Tutorial
http://www.digital-geography.com/create-point-density-raster-in-qgis/#.U7LZznVdUbw
) . So I think that I have everything correctly installed. But, when I use
my own data (from 100 to 1000 points) I just get an empty raster with "nan"
values in it.
I tried to use a geographic coordinate system and a projected coordinate
system. I tried too to use small and large radius, but I just get the same
empty raster.
Thanks for your help. Any help will be appreciated.
