How to measure land with MapLab Survey
Land measurement is more than drawing on a screen. You need purpose, accuracy, coordinate system and delivery format.
Field takeaways
- Reconnaissance, cadastre and construction stake-out require different accuracy levels.
- Define project, CRS, layers and delivery format before fieldwork.
- Parcels and fields are measured as polygons for area and perimeter.
- Critical work needs external GNSS/RTK and control checks.
- MapLab Survey keeps measurements, notes, photos, layers and exports together.
1. Decide what the measurement is for
Seeing a field's rough area, drawing a site working boundary, checking a parcel corner and doing official cadastral work are four different jobs. That is the first decision. For scouting and planning, phone positioning is usually enough; for precise boundaries, stake-out, payment measurements or engineering delivery, you need an external GNSS/RTK receiver, control points and the authorised process.
2. Set up the project and the coordinate system
Name the project, the date and the type of work clearly. In Türkiye a technical delivery may involve TM, ED50, WGS84 or UTM systems; drawing correctly is not enough if the coordinate system and EPSG information are not kept with the file, because that is what makes it open correctly at the office.
3. Split the layers by field task
Layer discipline looks unnecessary on a small job and saves the day on a big one. Layers like parcel_boundary, survey_point, road_edge, level and note reduce the rework at the office, and photos and descriptions stay attached to their points.
4. Measure points, lines and polygons
Individual details are points, road edges and line work are lines, parcel and field boundaries are polygons. Record a corner point where the boundary turns and let the straight sections run between them; the polygon must close, and since the area is computed from it, one bad corner distorts the whole result.
5. Check before you deliver
Reopen the file when the measuring ends. Is the area plausible, does any line self-intersect, is a Z value absurd, are the layers mixed, is the coordinate system right? On critical work, return to the starting control point and note the difference. Five minutes in the field saves half a day at the office.
6. Choose the delivery per recipient
KML/KMZ for a site manager who wants Google Earth, DXF for the CAD team, GeoJSON for GIS analysis, CSV for a point list — all from the same field data. Leave the source, date, coordinate system and method note next to every file; a bare number cannot be verified by anyone, including you in six months.
Try these steps on your own phone.
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 land be measured with a phone?
For reconnaissance yes; precise work needs external GNSS/RTK and control.
How is area calculated?
By closing a polygon around the boundary.
Which export should I use?
DXF for CAD, KML/KMZ for Google Earth, GeoJSON for GIS and CSV for point lists.
