So I have a CSV with a lot of fields. The first 3 fields are the ID, longitude, and latitude. I have already converted to decimal degrees, and said to display XY data. (Is there something else I need to do before I can use these points?)
Now I need to know what Spatial Analyst tool to use to extract the elevation for each point, and how to use that tool. I tried extract by mask and Extract Multi Values to points, but neither worked.
Extract by mask left me with just one elevation for all 531 points. Extract by multi values failed to execute.
What do you think? I'm very inexperienced, so a step-by-step guide would help a lot.
