How to query a parcel and add it as a layer in MapLab Survey
A common field question is how to find a parcel, add it as a layer and measure around it.
Field takeaways
- Parcel query helps locate official parcel information, but field checks are still required.
- MapLab Survey can use queried or map-selected parcels as layers for drawing and measurement.
- Satellite imagery may have offset and should not be treated as legal boundary evidence.
- Official property decisions rely on authorised records.
A queried parcel is a reference, not a boundary
Parcel geometry pulled from an online service shows roughly where the registered boundary sits. It is drawn at map accuracy and should be treated as a guide layer, not as corners to build against.
Load it as a layer, not a picture
Import the geometry so you can see it under your own measurements and compare the two on site. A screenshot cannot be measured against.
Compare, then explain the gap
Differences between the reference layer and what you measure are normal. Old cadastral work, walls built by eye and datum differences all contribute.
Keep the source and date
Note where the parcel data came from and when. Services update, and last year's layer will not match this year's.

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.
Frequently asked questions
Can a queried parcel be added as a layer?
Yes, the parcel can be used as a project layer for drawing and measurement.
Is parcel query a legal boundary decision?
No. Use authorised records and procedures for official decisions.
