About:
osmcoastline is a command-line tool designed to extract coastline data from OpenStreetMap planet files. It processes large OSM datasets to generate coastline geometries in formats like Shapefile or GeoPackage. This tool is essential for creating accurate marine boundaries for cartography and GIS applications.
Key Features:
  • Processes large planet files efficiently
  • Outputs to standard GIS formats (Shapefile, GeoPackage)
  • Handles OSM data inconsistencies and errors
  • Generates both lines and polygons for coastline representation
Use Cases:
  • Generating basemaps for marine navigation systems
  • Creating coastline data for GIS analysis and cartography
  • Preparing OSM data for rendering in map servers
Alternatives:
  • osm2pgsql – Imports full OSM data into a PostGIS database; requires more setup and is heavier than the focused extraction of osmcoastline.
  • Imposm – Another OSM importer focused on PostGIS, offering more customization for schema mapping.
