I am a beginner in ArcGIS. I have a query regarding merging many polygons to form one big polygon, and then rasterizing it. The polygons are from varied datasets and represent different environmentally protected areas, and I want to make them into one raster.
This can be done in a two step process...
- Use Merge to combine all your polygons into one polygon (tool found in the Data Management / General toolbox)
- Use Feature to Raster to change the polygon into a raster (tool found in the Conversion / To Raster toolbox).
These are both straightforward tools. The most complicated part with Feature to Raster is figuring out what cell size you should use (balancing accuracy and spatial resolution against the file size of the resulting raster).
