NAME

6       shputils - shapefile utility
7

SYNOPSIS

9       shputils in_shp_file out_shp_file args
10

DESCRIPTION

12       The  program  will append to an existing shape file or it will create a
13       new file if needed. Only the items in the first  output  file  will  be
14       preserved.  When  an item does not match with the append theme then the
15       item might be placed to an existing item at the same position and type.
16
17       OTHER FUNCTIONS:
18
19       ·   Describe all items in the dbase file (Use ALL for  more  than  5000
20           recs.)
21
22       ·   Select a group of shapes from a comma separated selection list.
23
24       ·   UnSelect a group of shapes from a comma separated selection list.
25
26       ·   Clip  boundary  extent  or  by theme boundary. Touch writes all the
27           shapes that touch the boundary. Inside writes all the  shapes  that
28           are completely within the boundary. Boundary clips are only the min
29           and max of a theme boundary.
30
31       ·   Erase boundary extent or by theme boundary.  Erase  is  the  direct
32           opposite of the Clip function.
33
34       ·   Change  coordinate value units between meters and feet. There is no
35           way to determine the input unit of a shape file. Skip this function
36           if  the  shape  file is already in the correct unit. Clip and Erase
37           will be done before the unit is changed. A shift will be done after
38           the unit is changed.
39
40       ·   Shift X and Y coordinates.
41
42
43
44       Finally,
45
46       There can only be one select or unselect in the command line.
47
48       There can only be one clip or erase in the command line. There can only
49       be one unit and only one shift in the command line.
