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.
An identifier is not a coordinate
A block and parcel number is a record reference, not a position. It has to be resolved to geometry through a cadastral query before it can guide anyone — and the province, district, neighbourhood and numbers must be right, because similarly named neighbourhoods and outdated identifiers cause real confusion in the field. Carry the result as KML/KMZ or a coordinate reference, not as a screenshot: an image cannot be measured, a layer can.
Adding it to the project
Add the parcel data as a layer and name it plainly, for example "cadastral parcel reference". Then check roads, gates, paths, fence lines and usable entry points on the ground; if you walk the boundary, record the track and add photo notes. Download the area map and identify the entry point while you still have coverage — road navigation stops where the road stops.
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. On arrival, compare the reference outline with what is on the ground and record any clear disagreement with a photograph.
What to look at on site
- Is there a road or passage around the parcel?
- Fences, walls, ditches, tree lines or old stakes?
- Does the neighbouring occupation match the reference?
- Does phone GPS weaken under trees or in a narrow valley?
- Does the measured area differ from the registered area?
The legal line
Seeing the parcel outline on a phone is genuinely useful, but it is not an official boundary determination. Cadastral boundaries are settled by the authority's data and, where needed, the authorised technical procedure — note that the in-app parcel query covers Türkiye. MapLab Survey provides field records and checks; it does not declare legal boundaries.

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.

Only approximately.
What should I photograph?
Fences, walls, ditches, stakes, access and uncertain corners.
