Wise Arc/Info users will guess that the IDENTITY command could be used to capture those data points within the project's area. It might be useful, however, to retain those points as a separate point coverage (the IDENTITY command would combine the sites with the poygon <identity_cover> so that data base ready files can be easily extracted. For this section, use the CLIP command:

Arc: clip

Usage: CLIP <in_cover> <clip_cover> <out_cover>

{POLY | LINE | POINT | NET | LINK | RAW} {fuzzy_tolerance}

Arc: clip sites_cctp proj_coqds proj_sites point

Clipping sites_cctp with proj_coqds to create proj_sites.

The resulting point coverage contains the following items:

In a later section the "proj_sites" coverage is combined with "proj_coqdsfed" to assign useful attributes (such as county, USGS quad, etc.) to the sites.
