This repository contains a bash script that splits and optionally inverts polygons in a spatialite database in a regular grid pattern with overlaps.
It is written for use for generating coastline polygon files on openstreetmapdata.com.
requires the following to operate:
- GDAL/OGR
- spatialite
- polysplit from https://github.com/geoloqi/polysplit.git (unless used with 'n'-option)
- tile_grid.py (should be included with this script)
