How to go from block parcel query to the field
A block and parcel number can guide you to the land, but it should be handled as a reference workflow, not a legal boundary declaration.
Field takeaways
- Use official parcel query sources for block and parcel lookup.
- Parcel KML can be used as a field reference layer.
- Phone GPS helps approach the parcel, not define legal boundaries.
- Record fences, walls and occupation evidence with photos.
- MapLab Survey organizes parcel, route, measurement and notes.
From identifier to position
A block and parcel number is a record reference, not a coordinate. It has to be resolved to geometry through a cadastral query before it can guide anyone.
The geometry is approximate
Queried parcel outlines are drawn at map accuracy. Use them to reach the plot and to orient yourself, not to identify corners.
Prepare access before you lose signal
Download the area map and identify the entry point while you still have coverage. Road navigation stops where the road stops.
Verify on arrival
Compare the reference outline with what is on the ground and record any clear disagreement with a photograph.

MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
