titan polygonize

Command line tool to convert classification (i.e. integer) rasters to vector polygons.

titan polygonize [-h] [--srcnodata value] [-b band]
                 [--of vector_format] [--four]
                 input_file output_file

Converts raster files to cloud-optimized geotiffs.

positional arguments:
  input_file          Input raster file path.
  output_file         Output vector file path.

optional arguments:
  -h, --help          show this help message and exit
  --srcnodata value   Input nodata value
  -b band             Band(s) to process
  --of vector_format  Output vector driver.
  --four              Use 4-neighbor connectivity instead of 8.

This scripts reads the full raster array into memory and creates polygon features for clusters of adjacent pixels sharing the same value. If you try and run this with a continuous floating point raster you're gonna have a bad time.
