11
13 in_shp_file
14 the name of an existing shapefile.
15
16 out_shp_file
17 the name of the new fixed shapefile that will be created.
18
19 -i Input projection. Input can come from one of three sources. A
20 projection parameter file, directly through parameters or geo‐
21 graphic. If the shapefile has an associated prj file, name the
22 same as the shapefile but ending in ".prj" it will be used by
23 default ignoring all other parameters. If input is omitted it
24 defaults to geographic, unless the default prj file exists.
25
26 -o Output can come from one of three sources. A projection parame‐
27 ter file, directly through parameters or geographic. If output
28 is omitted it defaults to geographic.
29
31 PROJECTION PARAMETER FILE
32 This file MUST end with the extension ".prj". It has the form of
33 one projection parameter per line. Parameters can be in any
34 order. The projection parameters are those used to define a PROJ
35 projection.
36
37 PROJECTION PARAMETERS
38 Are the same as used by proj and invproj.
39
40 use: proj -lu to see available units proj -le to see available ellip‐
41 soid

47 The following example projects file rowtest to row3, moving data from
48 Stateplane NAD83 zone 1002 to utm zone 16 in meters
49
50 shpproj rowtest row -i="init=nad83:1002 units=us-ft" -o="proj=utm
51 zone=16 units=m"
52
53 shpproj rowtest row3 -o="proj=utm zone=18 units=m" -i="zone=16 proj=utm
54 units=us-ft"
55
56 shpproj rowtest row3 -o="proj=utm zone=18 units=m"
57
58 This example uses a prj file and converts to geographic. note that
59 -o=geographic can be ommitted.

61 shpproj rowtest row3 -i=myfile.prj -o=geographic
