README.md

Data in MapComplete can come from multiple sources.

Currently, they are:

  • The Overpass-API
  • The OSM-API
  • One or more GeoJSON files. This can be a single file or a set of tiled geojson files
  • LocalStorage, containing features from a previous visit
  • Changes made by the user introducing new features

When the data enters from Overpass or from the OSM-API, they are first distributed per layer:

OVERPASS | ---PerLayerFeatureSource---> FeatureSourceForLayer[] OSM |

The GeoJSon files (not tiled) are then added to this list

A single FeatureSourcePerLayer is then further handled by splitting it into a tile hierarchy.

In order to keep thins snappy, they are distributed over a tiled database per layer.

Notes

cached-featuresbookcases is the old key used cahced-features{themeid} and should be cleaned up
