PROGRAM:

NAME

shpproj - Reproject Shapefiles using PROJ.4

SYNOPSIS

shpproj in_shp_file out_shp_file [-i=in_proj_file | -i="in_params" | -i=geographic]
[-o=out_info_file | -o="out_params" | -o=geographic]

OPTIONS

in_shp_file
the name of an existing shapefile.

out_shp_file
the name of the new fixed shapefile that will be created.

-i Input projection. Input can come from one of three sources. A projection parameter
file, directly through parameters or geographic. If the shapefile has an associated
prj file, name the same as the shapefile but ending in ".prj" it will be used by
default ignoring all other parameters. If input is omitted it defaults to
geographic, unless the default prj file exists.

-o Output can come from one of three sources. A projection parameter file, directly
through parameters or geographic. If output is omitted it defaults to geographic.

PROJECTION DETAILS

PROJECTION PARAMETER FILE
This file MUST end with the extension ".prj". It has the form of one projection
parameter per line. Parameters can be in any order. The projection parameters are
those used to define a PROJ.4 projection.

PROJECTION PARAMETERS
Are the same as used by proj and invproj.

use: proj -lu to see available units proj -le to see available ellipsoid

Or visit the PROJ.4 web page at http://www.remotesensing.org/proj for more details.

EXAMPLE

The following example projects file rowtest to row3, moving data from Stateplane NAD83
zone 1002 to utm zone 16 in meters

shpproj rowtest row -i="init=nad83:1002 units=us-ft" -o="proj=utm zone=16 units=m"

shpproj rowtest row3 -o="proj=utm zone=18 units=m" -i="zone=16 proj=utm units=us-ft"

shpproj rowtest row3 -o="proj=utm zone=18 units=m"

This example uses a prj file and converts to geographic. note that -o=geographic can be
ommitted.

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