Mapping

How are mapping and land measurement done with drone, RTK, phone and CAD/GIS

Mapping and land measurement are not one method. Drone, RTK, phone and CAD/GIS each solve a different part.

Field takeaways

  • Drone collects imagery; accurate mapping needs control and processing.
  • RTK is strong for field points and control.
  • Phone GPS is useful for reconnaissance and notes.
  • CAD/GIS delivery needs CRS, layers and formats.
  • MapLab Survey helps connect field control, KML/DXF and reports.

Choose the method

Before any instrument comes out, answer three questions: what tolerance the job needs, what the environment is like, and what format has to be delivered. Those answers decide the method better than any preference.

Combining is usually right

Many projects use a drone for coverage, RTK for control and a total station for detail under trees or against facades. What matters is that everything ends in the same coordinate system.

Ground control is not optional

Aerial work without measured ground control produces a model that looks convincing and sits in the wrong place.

Delivery decides

A perfect survey handed over in the wrong coordinate system is a lost survey. Write the EPSG code in the report from day one.

In the field · MapLab Survey

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

Is drone enough?

Not by itself for controlled accuracy.

Why use RTK?

For ground control and checks.

Why use phone?

For notes, photos, KML and reconnaissance.

Is MapLab Survey a drone app?

No, it supports field control and GIS delivery.
