How to convert polygons in single shapefile into rasters with model builder

VannarethHuoy1

I'm having a problem of overlaid polygons in a single shapefile. I want to convert all polygon to raster then sum the value of any polygon which area overlaid. if I convert this shape file into raster, it chose only the first polygon which is overlaid another to represent to value of cells. I'm thinking if I want to sum value of overlaid polygons together, I should separate each polygon to different shapefile then convert it to raster and use raster calculator to sum all rasters but there's about 15000 polygons within single shapefile, so I cannot manually select and convert it to raster one by one. I'm thinking about iterator in model builder but i 'm very new with model builder. So if anyone can help to solve the problem i explaint above? Your help is very much appreciated.

Your model will be like this

In the output of polygon to raster use- in_memory\%Value% . This will save the outputs in the memory and use them in the collect values.

Let me know if you need more details about the model

Hope this helps

Hi Jayanta,

Do you mean by marking the comment Helpful? If so, I just did it. If not, how can I mark this answer as correct.
