![]() Raster menu > Conversion > Rasterize (Vector to Raster) or in Processing Toolbox it is found in. If you don't have access to Spatial Analyst and can't install QGIS, GDAL or similar FOSS GIS, then the buffer-debuffer trick works reasonably well. You can use the Rasterize (Vector to Raster) tool to convert a polygon layer to raster layer. This sounds legitimate for your use case. Then when you have it reclassed, you can convert that to a shapefile and reassociate the raw information summary with the polygons. BUT just taking the int of the layer is going to yield you want too many classes. Again this depends on your licence but you could change the resolution of your raster and then use nibble or clean as per my suggestions in the previous thread cited above. you have to reclass it to an integer raster. Caution is needed here so as you don't do something that invalidates any statistics, but it looks like you are just wanting to extract features. If the field is integer, the output raster will be integer if it is floating point, the output will be floating point. The input field type determines the type of output raster. You will reduce your polygon count and raster 'look' of your data but at the expense of an increased vertex count.Īlternatively you can look at pre-processing the raster. Any feature class (geodatabase, shapefile or coverage) containing polygon features can be converted to a raster dataset. You need to use your judgement on how much to buffer by to avoid joining polygons that should remain separate. Usage The input raster can have any cell size and must be a valid integer raster dataset. ![]() One simple approach is to buffer your polygons and then de-buffer the result by the same or similar amount. Resource Center Summary Converts a raster dataset to polygon features. this question) and the answer depends very much on the tools you have available and the degree to which you can accept loss of precision and generalization. Polygons generated by raster to polygon arent multipart unless the OP has dissolved at some stage.
