Reliable sync
No cables needed. Field teams can push updates back in real time, with version history and cloud backup.
Mergin Maps: QGIS in your pocket
Mergin Maps is a field data collection tool built on the free and open-source QGIS. It helps your team collect, store, and synchronise field data without paper notes, manual photo georeferencing, or repeated GPS coordinate transcription.
Field GIS
Take QGIS projects into the field, then sync them back to the team.
Setting up a project only takes a few minutes: create your survey project in QGIS, connect it to Mergin Maps with the plugin, synchronise it with the mobile app, and start collecting data in the field.
Captured survey data is shown on a map and can be exported to CSV, Microsoft Excel, ESRI Shapefile, MapInfo, GeoPackage, PostGIS, AutoCAD DXF, and KML.
Capabilities
Built for real field conditions
Team collaboration
Share projects with multiple surveyors, even offline, while updates are intelligently merged.
GNSS workflows
Connect external GPS/GNSS devices via Bluetooth for high-precision surveying and metadata capture.
Offline maps
Configure offline or web-based background maps and contextual layers for work without data connection.
Forms + Data
Capture the information your operation actually needs.
Mergin Maps supports live position tracking, survey forms, points, lines, polygons, photos, checkboxes, drop-down values, date and time fields, numeric controls, and multi-line text.
It can also sync with PostGIS datasets and external media storage such as S3 and MinIO.
