On startup the base data is loaded and a spatial index is built and persisted using rtree. On next startup (if disk is persistent), it will only do an incremental update.
Spatial matching is done using bounding box intersection.
Transit decoding is supported.
This example matches lines to lines (bounding box is then a square around the line).
Example system config:
{
"_id": "my-spatial-mapper-transformer",
"type": "system:microservice",
"docker": {
"environment": {
"SOURCE_PROPERTY": "geometry",
"TARGET_PROPERTY": "matches",

"BASE_DATA_PROPERTY": "geojson"
},

}
