Specify AUTO-n where n is an integer greater orĮqual to 1, to select an overview level below the AUTO one. The default choice,ĪUTO, will select the overview level whose resolution is the closest to the To specify which overview level of source files must be used. The other dimension will be guessed from the computed resolution. Set output file size in pixels and lines. Xmax / resx and ymax / resy are integer values. Includes the minimum extent (edges lines/columns that are detected asīlank, before actual warping, will be removed starting with GDAL 3.8).Īlignment means that xmin / resx, ymin / resy, (target aligned pixels) align the coordinates of the extent of the outputįile to the values of the -tr, such that the aligned extent It is possible to ask square pixels to still be generated, by specifying Version, an output raster with xres=yres was always generated). Or RPC), the resolution of the source file(s) will be preserved (in previous That no reprojection is involved (including taking into account geolocation arrays Starting with GDAL 3.7, if neither -tr nor -ts are specified, General case, generate an output raster with xres=yres.

Set georeferenced extents of output file to be created (in target SRS byĭefault, or in the SRS specified with -te_srs) -te_srs If minimum_gcps is not provided, the minimum GCPs according to the polynomial model is used. The tolerance is in pixel units if no projection is available, otherwise it is in SRS units. Not that GCP refinement only works with polynomial interpolation. The tolerance is passed to adjust when a GCP will be eliminated. Outliers will be eliminated until minimum_gcps are left or when no outliers can be detected.
