How to share a KML file with WhatsApp and open it on a phone
KML often arrives through WhatsApp in the field. Opening it is easy; preserving meaning and context is the important part.
Field takeaways
- KML carries map features such as points, lines and polygons.
- WhatsApp can weaken file naming and context.
- KMZ is a packaged KML file.
- MapLab Survey can use KML as a reference layer.
- Official boundary and CRS context must be checked separately.
Send it as a document
Attach the KML as a file. Sent as an image or screenshot, the recipient gets a picture rather than data they can use.
Open it in a map app
On the phone, open the file with an application that can import it as a layer. Then it can be seen over the terrain and measured against, not merely viewed.
The ten-second check
When it opens, confirm the geometry falls where it should. A KML that appears in another country almost always comes from a coordinate problem at source.
Write what the file does not say
Add a line giving the survey date, the method and what the boundary represents.
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.
