Hi,
I have these geometry tables COUNTRY STATES (polygon), ROADS(line) and LIGHTNING(point). I want to create a tiff map file of lightining density. I choose a period of lightning and each pixel value is set with number of lightinings. The roads are also displayed above all. I read some articles how to create raster files, and my main concern is how to make the raster table and set the pixel values with the number of lightinings in a fast way. Regards, Liglio
