Suggested data set specifications for a warp destination

val suggested_warp_output : Data_set.t -> _ Transform.t -> warp_output_t

suggested_warp_output ds transform will suggest dimensions and Geo_transform.t parameters for a destination data set to warp ds into based on the dimensions of ds and the parameters defined in transform.

reproject_image ?memory_limit ?max_error ?options ?src_wkt ?dst_wkt ~src ~dst alg reprojects the image src to dst, overwriting dst in the process.

parameter memory_limit
is specified in bytes.

parameter max_error
is the maximum error allowed between the src and dst. Defaults to 0.0.

parameter src_wkt
may be used to override the projection information in src.

parameter dst_wkt
may be used to override the projection information in dst.

parameter alg
specifies which resampling algorithm to use.

raises Warp_error
if the operation can not be performed.

create_and_reproject_image ?memory_limit ?max_error ?options ?src_wkt ?dst_wkt ?create_options src filename driver alg reprojects the image src to filename.

parameter memory_limit
is specified in bytes.

parameter max_error
is the maximum error allowed between the src and dst. Defaults to 0.0.

parameter src_wkt
may be used to override the projection information in src.

parameter dst_wkt
specifies the projection to use when creating filename. Defaults to the same projection as src.

parameter filename
specifies the file to write the result to.

parameter driver
specifies the driver to use when creating filename.

parameter alg
specifies which resampling algorithm to use.

raises Warp_error
if the operation can not be performed.

auto_create_warped_vrt ?src_wkt ?dst_wkt ?max_error ?options src alg creates a virtual dataset warped from src.

parameter src_wkt
may be used to override the projection information in src.

parameter dst_wkt
specifies the projection to use when creating filename. Defaults to the same projection as src.

parameter max_error
is the maximum error allowed between the src and dst. Defaults to 0.0.

parameter alg
specifies which resampling algorithm to use.

raises Warp_error
if the operation can not be performed.
