v0.1.0

First tagged release.

▶ Live demo

The map is one JSON document. The core diffs two versions of it and emits a list
of operations; an adapter applies them to MapLibre. Swapping the basemap does not
destroy your layers, and undo is sixty whole documents deep.

In this release

• Data in — GeoJSON, zipped Shapefile, GeoPackage, KML and GPX, by upload or
  by URL, reprojected into PostGIS and served back as vector tiles. WMS layers
  picked from GetCapabilities.
• Imagery — GeoTIFFs converted to COGs and indexed by footprint, mosaicked on
  demand with band selection, stretch and band maths as query parameters.
• Symbology — single, graduated and categorised, with markers, labels and
  per-layer scale ranges.
• Filters — one filter structure compiles to both a renderer expression and
  parameterised SQL.
• 2D, 2.5D and 3D — three projections including a real globe, terrain and
  hillshade, and OSM buildings at their real height.
• 3D models — glTF placed by position, height, bearing and scale, standing on
  the terrain and lit by the real sun.
• Live assets — positions over a WebSocket as an ordinary layer; assets that
  go quiet are drawn hollow rather than deleted.
• Drawing — geodesic measurement, buffers, snapping and vertex editing, with
  export and import in GeoJSON, KML, GPX, CSV and WKT.
