NAME
       gdaltransform - Transforms coordinates.

SYNOPSIS
       gdaltransform [--help-general]
	   [-i] [-s_srs srs_def] [-t_srs srs_def] [-to "NAME=VALUE"]
	   [-order n] [-tps] [-rpc] [-geoloc]
	   [-gcp pixel line easting northing [elevation]]* [-output_xy]
	   [srcfile [dstfile]]

DESCRIPTION
       The gdaltransform utility reprojects a list of coordinates into any
       supported projection,including GCP-based transformations.

       -s_srs srs def:
	   source spatial reference set. The coordinate systems that can be
	   passed are anything supported by the
	   OGRSpatialReference.SetFromUserInput() call, which includes EPSG
	   PCS and GCSes (i.e. EPSG:4296), PROJ.4 declarations (as above), or
	   the name of a .prj file containing well known text.

       -t_srs srs_def:
	   target spatial reference set. The coordinate systems that can be
	   passed are anything supported by the
	   OGRSpatialReference.SetFromUserInput() call, which includes EPSG
	   PCS and GCSes (i.e. EPSG:4296), PROJ.4 declarations (as above), or
	   the name of a .prj file containing well known text.

       -to NAME=VALUE:
	   set a transformer option suitable to pass to
	   GDALCreateGenImgProjTransformer2().

       -order n:
	   order of polynomial used for warping (1 to 3). The default is to
	   select a polynomial order based on the number of GCPs.

       -tps:
	   Force use of thin plate spline transformer based on available GCPs.

       -rpc:
	   Force use of RPCs.

       -geoloc:
	   Force use of Geolocation Arrays.

       -i  Inverse transformation: from destination to source.

       -gcppixel line easting northing [elevation]:
	   Provide a GCP to be used for transformation (generally three or
	   more are required)

       -output_xy:
	   (GDAL >= 2.0) Restrict output to 'x y' instead of 'x y z'

       srcfile:
	   File with source projection definition or GCP's. If not given,
	   source projection is read from the command-line -s_srs or -gcp
	   parameters

       dstfile:
	   File with destination projection definition.

       Coordinates are read as pairs (or triples) of numbers per line from
       standard input, transformed, and written out to standard output in the
       same way. All transformations offered by gdalwarp are handled,
       including gcp-based ones.

       Note that input and output must always be in decimal form. There is
       currently no support for DMS input or output.

       If an input image file is provided, input is in pixel/line coordinates
       on that image. If an output file is provided, output is in pixel/line
       coordinates on that image.

Reprojection Example
       Simple reprojection from one projected coordinate system to another:

       gdaltransform -s_srs EPSG:28992 -t_srs EPSG:31370
       177502 311865

       Produces the following output in meters in the 'Belge 1972 / Belgian
       Lambert 72' projection:

       244510.77404604 166154.532871342 -1046.79270555763

Image RPC Example
       The following command requests an RPC based transformation using the
       RPC model associated with the named file. Because the -i (inverse) flag
       is used, the transformation is from output georeferenced (WGS84)
       coordinates back to image coordinates.

       gdaltransform -i -rpc 06OCT20025052-P2AS-005553965230_01_P001.TIF
       125.67206 39.85307 50

       Produces this output measured in pixels and lines on the image:

       3499.49282422381 2910.83892848414 50
