gdal_extent.py

A command-line utility for getting the extent (bounds) of any raster as Well-Known Text (WKT), GeoJSON, or other vector formats. It is intended to compliment the library of GDAL utilities already available.

Utilities

Default behavior at CLI; to get the rectangular extent of a raster in the format expected by other GDAL utiltiies, e.g., the -te switch with gdal_rasterize:

$ ./gdal_extent.py Wayne_county.tiff
289965.0 4655115.0 346215.0 4701645.0

To get the width/height of a raster:

$ ./gdal_extent.py --size Wayne_county.tiff
1875 1551

To get a GeoJSON Polygon for the rectangular extent as a string, with 2 spaces for indentation:

$ ./gdal_extent.py --extent --as-json -i 2 Wayne_county.tiff
