mapfile_writer library

A library for writing and creating Mapsforge .map files.

This is intended for advanced use cases where you need to generate your own map files from other data sources. It provides the tools to construct the header, index, and data blocks required for a valid .map file.

It exports:

  • MapfileWriter: The main class for orchestrating the map file creation process.
  • SubfileCreator: A helper for creating the various sub-files within a .map file.
  • SubfileFiller: A helper for populating the sub-files with data.
  • WayHolder: A data holder for way information during the writing process.
