I'm trying to extract Sea Surface Temp raster (floating integer) that includes both sea temp and land surface temp. I want the data outside of a clip. I've clipped the coastline with a polygon in Arc 10.2, however, the issue is with the remaining desired data outside of a polygon. I've tried extract by mask without success as it will only return values within the polygon and not outside of it. Any suggestions would be helpful.

  • Would simply using the Erase tool in the Analysis toolbox suffice? – Jesse Nov 12 '14 at 22:17

  • Make a big polygon around your entire study area, on and offshore
  • Use the Symmetrical Difference tool to get the difference between your coastline polygon and your study area polygon to create an offshore polygon
  • Extract your raster data using the offshore polygon
  • @JenniG fantastic!!! – DPSSpatial Nov 12 '14 at 22:39
