I'm on a steep learnig curve here, so aplogies if my question is a one-banana problem.
In ArcGIS 10 I have a contour layer that was generated from an ESR ASCII raster file (batyhmetry of the South Pacific). I also have a point layer (indicating certain seabird breeding locations). For each point I produced 20km buffer zones. So far so good.
What I need to do now, is clip the circular buffer zones so that only the buffer regions between two contour lines remain (in my the case 0m and 150m isolines).
Is there a way in ArcGIS to clip/remove the buffer zones that are outside the 0-150m contours?
