A tool for mosaicking together a set of raster tiles so that the output is only provided in areas where there is data in a user-provided validity mask.
Most effective when the validity mask is a tiled sparse GeoTIFF, as the code goes through the validity mask block by block and does not attempt mosaicking at the empty blocks in the validity mask.
raster_mosaicker.exe -m [MASK.TIF] -i [TILE_INPUT_PATH] -l [TILE_LIST.TXT] -o [DST_FILENAME.TIF] [-v]
Mosaics the tiles located at TILE_INPUT_PATH based on the tile filepaths (relative to TILE_INPUT_PATH) given in TILE_LIST (whose path is also relative to TILE_INPUT_PATH). Only mosaics areas that contain a valid value in MASK.TIF raster.
Tested on VS 2019, GDAL 3.3.0dev (2020-12-15 nightly build), and PROJ 8.0, but probably works on older versions, too. The dependencies can be installed with the OSGeow4 installer; remember to change the paths if you are using CMake to build the project.
If you get the error ERROR 1: PROJ: proj_create_from_database: Cannot find proj.db, you have to set the environment PROJ_LIB to point to the build output directory. That is where the proj.db database file is copied during the build.
