I am currently trying to convert a list of polygons to individual rasters. Using Arcgis Desktop's 'convert polygon to raster', this is rather simple. But since the polygons are rather spread out, each time i create a raster (for 1 polygon), it uses the entire extent of the feature class, which means the resulting raster is unnecessarily big (with many nodata cells).

I was therefore wondering, if its possible to choose the specific polygon's extent, instead of choosing all polygons' extents? I have tried extracting each separate polygon beforehand, but it seems a bit slow.

I will try to implement the entire analysis (which is a bit longer) in arcpy afterwards, so if the solution is easier to find in there, that might help aswell.

edit: I think i might i have been vague in my description. I mean i have a feature class containing multiple polygons. is there a way to select the extent of one of these polygons? right now i can only select layers (i.e. the feature class and all of its polygons), not separate polygons in the feature class.

In the environments you can set the processing extent to each individual polygon. You will have to do this each time you convert from polygon to raster.

Geoprocessing tab> Environments> Processing Extent> Select the polygon you want to convert to a raster

Hope this helps

  • Depending on the number of polygons you have. It may be simplest to select the polygon you wish to set the extent too and export the data to a new layer. To do this Select the data>right click on the layer containing the data> select export data> change the option to selected data>save. After you have completed this you would then follow my original instructions.
