GeofileOps 0.8.1#
GeofileOps is a python toolbox to process large vector files faster.
Most typical GIS operations are available: e.g. buffer(), simplify(),
dissolve(), intersection(),… You can also run custom logic by using
apply(), select() or select_two_layers().
The spatial operations are tested on geopackage and shapefile input files, but geopackage is recommended as it will give better performance. General layer and file operations can be used on the file formats supported by GDAL.
Different techniques are used under the hood to be able to process large files as fast as possible:
process data in batches
subdivide/merge complex geometries on the fly
process data in different passes
use all available CPUs
The following chart gives an impression of the speed improvement that can be expected when processing larger files. The benchmarks ran on a Windows PC with 12 cores and include I/O.
