Notes for GIS users

SPAN (School Property Account Number, 'TTT-CCC-NNNNN') is the statewide-unique id. Polygons with PROPTYPE other than 'PARCEL' (e.g. ROW_ROAD, WATER) are rights-of-way etc. with no grand list data; filter PROPTYPE = 'PARCEL' when a point lands on a road.

How to use it

QGIS: Layer > Data Source Manager > ArcGIS REST Server, add a connection with the service URL (the endpoint above without the final /0), then add the layer. Filter to your area before exporting.
ArcGIS Pro: Add Data > Data From Path, paste the endpoint.
Direct query: append /query?geometry=LON,LAT&geometryType=esriGeometryPoint&inSR=4326&spatialRel=esriSpatialRelIntersects&outFields=*&f=geojson to get the parcel at a point.
CAD: see getting a parcel into AutoCAD or Civil 3D.

Assessor parcel lines are for taxation and are often 5 to 50 ft off the legal boundary. Why.

Basesheet uses this to draw the parcel line on a base plan for any Vermont address, with LiDAR contours, soils, flood zones and wetlands.
