topic Divide a raster map by maeans of a polygon in Data Management Questions https://community.esri.com/t5/data-management-questions/divide-a-raster-map-by-maeans-of-a-polygon/m-p/146399#M8305 <HTML><HEAD></HEAD><BODY><SPAN>Dear collegues,</SPAN><BR /><BR /><SPAN>I would like to know if it is possible to individualize a raster map by means of a polygon (feature). Like I show in the figure below, I have this raster map with diferent colours and I would like to separate according to the diferent polygons I have on it (black lines). My objective is to be able to work with each part of the raster individually. I have been thinking of vectorizing the raster map and then apply a "clip", "union" or intersect with the polygons but i would like to keep the raster format.</SPAN><BR /><BR /><SPAN>Best wishes,</SPAN><BR /><BR /><SPAN>Guillem</SPAN></BODY></HTML> Wed, 26 Jan 2011 04:45:30 GMT GuillemDomènech_i_Surinyach 2011-01-26T04:45:30Z Divide a raster map by maeans of a polygon https://community.esri.com/t5/data-management-questions/divide-a-raster-map-by-maeans-of-a-polygon/m-p/146399#M8305 <HTML><HEAD></HEAD><BODY><SPAN>Dear collegues,</SPAN><BR /><BR /><SPAN>I would like to know if it is possible to individualize a raster map by means of a polygon (feature).
