If my question was not clear I can always rewrite it. Luciano Hello QGIS users, I have a raster image of human population counts (LandScan) of approximately 1 km resolution. I need to take each cell of the raster one by one and retrieve the population count for that cell. To do this, I was told to create a grid theme of population density - based on the grid themes specifying population counts and area. Export population count and population density files from ArcView to *.asc files. Since your Landscan grid is at resolution 1 km, then the population count and density (per sq km) should be the same. Using the GRASS module r.out.xyz you can get an ASCII text file with three columns: X,Y,value. The X-Y are cell enters, and value would represent Population count. I am not sure how to create the grid nor how to export pop count and density files to *.asc. Any tips? Thank you in advance!
