Geoscience Reference
In-Depth Information
supported by the OGRSpatialReference.SetFromUserInput() call, which includes
EPSG PCS and GCSes (ie. EPSG:4296), PROJ.4 declarations (as above), or the
name of a .prf file containing well known text.
-to NAME=VALUE
set a transformer option suitable to pass to GDALCreateGenImgProjTrans-
former2().
-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.
-et err_threshold
error threshold for transformation approximation (in pixel units - defaults to
0.125).
-refine_gcps tolerance minimum_gcps
(from GDAL 1.9.0) refines the GCPs by automatically eliminating outliers.
Outliers will be eliminated until minimum_gcps are left or when no outliers
can be detected. The tolerance is passed to adjust when a GCP will be elimi-
nated. Not that GCP refinement only works with polynomial interpolation. The
tolerance is in pixel units if no projection is available, otherwise it is in SRS
units. If minimum_gcps is not provided, the minimum GCPs according to the
polynomial model is used.
-te xmin ymin xmax ymax
set georeferenced extents of output file to be created (in target SRS).
-tr xres yres
set output file resolution (in target georeferenced units)
-tap
(from GDAL 1.8.0) (target aligned pixels) align the coordinates of the extent of
the output file to the values of the -tr, such that the aligned extent includes the
minimum extent.
-ts width height
set output file size in pixels and lines. If width or height is set to 0, the other
dimension will be guessed from the computed resolution. Note that -ts cannot be
used with -tr.
-wo "NAME=VALUE"
Set a warp options. The GDALWarpOptions::papszWarpOptions docs show all
options. Multiple -wo options may be listed.
-ot type
For the output bands to be of the indicated data type.
