shpproj - Man Page
Name
shpproj — Reproject Shapefiles using PROJ
##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 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 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
