geosplit 0.1.0

Split GeoJSON by feature count or file size and convert GeoJSON to and from GeoPackage

GeoSplit

A focused command-line tool that:

• splits a GeoJSON FeatureCollection by feature count;
• splits it by a strict maximum file size; and
• converts GeoJSON to GeoPackage, or a GeoPackage layer back to GeoJSON.

The splitter has no runtime dependencies. GeoPackage support is optional.

Install

Requires Python 3.10 or newer. Download or clone the project, open a terminal in its folder, then run:

pip install .

Include conversion support:

pip install ".[gpkg]"

Split GeoJSON

By feature count:

geosplit split world.geojson output --features 1000

By maximum file size:

geosplit split world.geojson output --size 10MB

Sizes accept B, KB, KiB, MB, MiB, GB, and GiB. Each resulting file is a complete, compact GeoJSON document whose on-disk size does not exceed the requested limit. If one feature cannot fit by itself, the command stops with a clear error.

Use --prefix countries to customize output names or --force to replace matching files. A source collection's top-level bbox is omitted because it would no longer describe each split collection; other top-level metadata is retained.

Convert formats

# GeoJSON to GeoPackage
geosplit convert roads.geojson roads.gpkg

# Choose the new GeoPackage layer name
geosplit convert roads.geojson map.gpkg --output-layer roads

# GeoPackage to GeoJSON
geosplit convert map.gpkg roads.geojson --layer roads

If a GeoPackage contains exactly one layer, --layer is optional. Existing destinations are protected unless --force is supplied.
