I have some points in .shp vector file and I need to convert them in .tif file with 1km x 1km resolution. The problem is - there are some points in one cell during conversion, and some values are missed. How can I convert these point without missing? Is there any function that will sum values in cell(in QGIS)? Any suggestion are acceptable.
First create a corresponding grid with:
Vector / Research tool / Vector grid (polygon)
Then use the join attributes with sum:
Vector / Data management tools / Join attributes by location
And finally rasterize the polygon according to the calculated attribute:
Raster / Conversion / Rasterize
