How to query a parcel on a phone and prepare it for field measurement
Parcel query on a phone is a practical preparation step before going to the field.
Field takeaways
- Official parcel query helps locate and inspect parcel data.
- Parcel lines can be used as reference, not legal boundary declaration.
- KML/KMZ can be used as a MapLab Survey layer.
- Phone GPS helps navigate near the parcel, not set corners.
- Report the data source when measuring area and perimeter.
Finding the parcel on a phone
Search by block/parcel number, province and district, or just tap the map. The aim is usually to see the place before travelling, understand the neighbouring parcels and prepare field notes. The query returns the parcel geometry with its block/parcel and sheet identifiers; you can save the geometry as a layer and have the identifiers written into attributes automatically.
How it connects to MapLab Survey
Treat the parcel line as a reference layer: open the queried parcel as its own layer, then add your measurements, photos and notes beside it. Never mix your own measurement into the reference layer — the separation between "official reference" and "my measurement" is the insurance against every later argument.
From query to field
Query and save the parcel at the office; turn the corner coordinates into a target list if you plan to visit them; walk to the corners with stake-out guidance; record a photo and note at each. This flow turns "where is the parcel?" from an hour of wandering into a five-minute procedure.
The limit of query data
The line a parcel query returns is for viewing; it is not a registration survey. The fence on the ground may disagree with it, and that alone establishes no claim. Official boundary determination is licensed surveying work — query data is the best preparation to carry into it.
A Türkiye-specific note
Parcel query and the MTA geology/active-fault layers are available in the app within Türkiye. Working elsewhere, you build the same flow by importing that country's cadastral data as KML/DXF.

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.
