wmsdump

A library and command-line tool for extracting vector layer data from OGC services (WMS, WFS).

Note: This tool only supports vector layers. Raster layers are not supported.

Checkpoint compatibility in 0.3.0

Breaking change: Saved checkpoints must contain output_bytes. Older checkpoint formats without this field are unsupported in every retrieval mode. They are rejected without reading or modifying the output; there is no automatic migration or recount fallback. Finish those downloads with the version that created them, or start a new extraction.

OFFSET recovery uses the saved byte boundary and record count without rescanning the output. Use --verify-record-count when an explicit recount is needed. EXTENT modes still read the output to rebuild their deduplication index.

Features

  • Supports WMS and WFS: Extracts data from both Web Map Service (WMS) and Web Feature Service (WFS) endpoints.
  • Flexible Retrieval Modes: Offers OFFSET (paged retrieval) and EXTENT (bbox splitting and drilling down by spatial extent) retrieval modes for…
