geofileops 0.8.1a0

Package to do spatial operations on large geo files.

geofileops

Geofileops aims to speed up spatial analysis on large/complex vector datasets.

It provides an easy to use API that can accomplish a lot with few lines of code. Most typical GIS operations are available: e.g. buffer, dissolve, erase/difference, intersection, union,...

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.

The full documentation is available on readthedocs.

Performance

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.
