I have imported an excel spreadsheet to my map and the points have fallen into certain locations. How do I add the location of the polygon that the point has landed in, to the attributes table of the point without hand jamming it all in one point at a time? For instance a table full of school locations has no county data in the table. How would I add the county to the schools attribute table?

    You're looking for "point in polygon" analysis. How you find it will depend on which GIS software you're using. – user3461 Aug 5 '13 at 16:12

    Look for a Spatial Join tool. – user3461 Aug 5 '13 at 16:18

    Can you edit your question to include details of the GIS software you are using, please? – PolyGeo Aug 5 '13 at 20:10
  • GeoRover RPF tool is what i used to import the excel spread sheet. just looking at the spread sheet i have no idea where the schools are located. But when i import the spread sheet to ArcMap with the county shapefile already in the map I can visually see where the schools land what I want to do is based on the county shape add a field to the shools attribute table and import the county the point falls with in. What programs would i need to accomplish this? – JoshJones Aug 6 '13 at 5:19

Use a Spatial Join with the school points and county polygons loaded in ArcMap.

  1. right-click the schools layer, highlight Joins & Relates, and click Join
  2. choose Join data from another layer based on spatial location
  3. the Layer to Join is your county layer
  4. each point should be given the attributes of the polygon that it falls inside
  5. specify an output shapefile or feature class name and click OK
  6. add the new layer to the map and examine its attributes to see which county each school lies in

I believe you can simply use "intersect" function in ArcGIS. Simply by intersecting your polygon layer with your DMS point layer
