geofileops 0.8.0a9

Package to do spatial operations on large geo files.

geofileops

This python library aims to make it easier and faster to develop spatial analysis on large vector GIS files.

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, Check out the API reference for a full list.

Geofileops is tested on geopackage and shapefile input files. However, geopackage is recommended as it will give better performance for most operations.

The aim is that there is no size limit on the files that can be processed on standard hardware. To make processing faster, the operations can use all available CPU's. In some cases (complex) geometries will be cut in smaller tiles to speed up processing further. For operations like buffer this won't make a big difference as it doesn't need a lot of CPU power, but calculating the intersection between two large files, dissolving large files,... will be a lot faster.

The following chart gives an impression of the speed improvement that can be expected when processing larger files (including I/O!) with 10 CPU's available. More information about this benchmark can be found here.
