I have a huge text file of points (1 million) with latitudes and longitudes.
Is there a fast way to identify the points inside the U.S. and keep them?
Thanks.

First, you should have a US map (Polygon shapefile),
then, import your point data into ArcGIS, create a point shapefile,
then, clip the point shapefile by the US polygon shapefile,
you get a a clipped US polygon shapefile.In this map, the points in US have
been merged into the US map. Go to the dbf file associated with the clipped
file, you get the points in the US. You can import data into Excel or SAS
to do future analysis.
