I have a raster polygon. I need to avoid certain area (another raster) from that raster. I need to avoid a watershed sub basin area that has its area on other basin also. How can I remove that basin?

For example:

I have the raster or shapefile of a country and I also have the shapefile or raster of a state in that country. I need to get the shapefile or raster of the country without the state I have.

I need to mask, but if I extract by mask, it gives the output as the boundary of the layer that we specified, but I need the rest of the area from the input.

  • Would you be able to edit your question to explain what you mean by "avoid" and "remove", please? I think your question must be about masking and that including a diagram would make what you are asking much clearer. – PolyGeo♦ Feb 16 '15 at 6:20

  • There is an edit button beneath your question that you can use to improve it with additional details and clarifications like this. – PolyGeo♦ Feb 16 '15 at 9:57

In ArcGis this is done through the environment setting of your analysis. See the mask explanation on the link.
