For Arc/Info users, use the IDENTITY command to capture that information in one coverage, which lies inside the features of another. The resulting coverage has all the features of the identity_cover> plus those of the <in_cover> which are inside the <identity_cover>.

NOTE: With the IDENTITY command, the <identity_cover> must be a polygon cover.

The <in_cover> can be point, line, or polygon.

Arc: identity

Usage: IDENTITY <in_cover> <identity_cover> <out_cover> {POLY | LINE | POINT}

{fuzzy_tolerance} {JOIN | NOJOIN}

Arc: identity usfsland proj_coqds proj_coqdsfed poly

Arc: identity usfsland proj_coqds proj_coqdsfed poly

Use the dropitem command to drop unnecessary .PAT items:

Arc: dropitem proj_coqdsfed.pat proj_coqdsfed.pat va_cnty#

TIP: When dropping several items from a .PAT, typing:

dropitem proj_coqdsfed.pat proj_coqdsfed.pat

Brings up a Arc prompt which allows to to specific many items:

Arc:dropitem proj_coqdsfed.pat proj_coqdsfed.pat

Enter item names (type END or a blank line when done):
