Description This function writes a GeoTIFF file. The input data must be a structure from read_geo() This function relies on GDAL > 1.8.
Arguments and Return Values Arguments: A Geo-Struct and file name Return Value: none
Usage Syntax: write_geotiff(Geo-Struct, filename [,force=BOOL][,subdata=INT][,a_srs=STRING]) Geo-Struct - the davinci Geo-Struct filename - full path to data force - force the creation/overwrite of the specified file a_srs - source projection argument (either a proj string or wkt), assigned by default values in Geo-Struct subdata - write out only the subdataset specified. Currently we only support the writing of 1 subdataset.
Examples dv> a=read_geo($DV_EX+"/I01001001.cub")
