gdal_merge - mosaics a set of imagesSYNOPSIS

DESCRIPTION
This utility will automatically mosaic a set of images. All the images must be in the same coordinate system and have a matching number of bands, but they may be overlapping, and at different resolutions.
- -o out_filename:
- The name of the output file, which will be created if it does not already exist (defaults to 'out.tif').
- -of format:
- Output format, defaults to GeoTIFF (GTiff).
- -co NAME=VALUE:
- Creation option for output file. Multiple options can be specified.
- -ot datatype:
- Force the output image bands to have a specific type. Use type names (ie. Byte, Int16,...)
- -ps pixelsize_x pixelsize_y:
- Pixel size to be used for the output file. If not specified the resolution of the first input file will be used.
- -ul_lr ulx uly lrx lry:
- The extents of the output file. If not specified the aggregate extents of all input files will be used.
- -v:
- Generate verbose output of mosaicing operations as they are done.
- -separate:
- Place each input file into a separate stacked band.
- -pct:
- Grab a pseudocolor table from the first input image, and use it for the output. Merging pseudocolored images this way assumes that all input files use the same color table.
- -n nodata_value:
- Ignore pixels from files being merged in with this pixel value.
- -init value:
- Pre-initialize the output file with this value. However, it is not marked as the nodata value in the output file.
- -createonly:
- The output file is created (and potentially pre-initialized) but no input image data is copied into it.
NOTE: gdal_merge.py is a Python script, and will only work if GDAL was built with Python support.
