Description
Mergin Maps is a field data collection tool built on the free and open-source QGIS which allows you to collect, store and synchronise your data with your team. It removes the pain of writing down paper notes, georeferencing photos and transcribing GPS coordinates. With Mergin Maps, you can get your QGIS projects into the mobile app, collect data and synchronise it back on the server.
Mergin Maps is a mobile GIS app designed to support a wide range of field mapping and GIS survey tasks. It is used by professionals across industries such as agriculture, telecommunication, fiber optics, construction and engineering, environmental protection, forestry, utilities, and local government and municipalities. Whether you're working in remote areas or connected environments, Mergin Maps enables efficient, accurate, and collaborative GIS data collection and management of geospatial datasets in the field.
Setting up your project with Mergin Maps only takes a few minutes. First, create your survey project in QGIS, then connect it to Mergin Maps with a plugin and synchronise it with the mobile app to start collecting in the field.
The data you capture in the field survey is shown on a map and can be exported to a wide variety of formats including CSV, Microsoft Excel, ESRI Shapefile, Mapinfo, GeoPackage, PostGIS, AutoCAD DXF, and KML.
Mergin Maps allows you to do live position tracking, fill out survey forms and capture and edit points, lines or polygons. You can also connect external GPS/GNSS devices via Bluetooth for high-precision surveying. Map layers look the same as in QGIS desktop so you can set your layer symbology how you want it on the desktop and it will appear that way on your mobile device.
Mergin Maps supports offline field data capture for situations where a data connection is unavailable. It can be configured to use either offline or web-based background maps and contextual layers.
Perks of the Mergin Maps sync system: - No need for cables to get your data on/off your device - Share projects with others for collaborative working, even offline - Updates from different surveyors are intelligently merged - Push data back from the field in real time - Version history and cloud-based backup - Fine-grained access control - Record metadata such as EXIF, GPS and external GNSS device information - Sync with your PostGIS datasets and external media storage such as S3 and MinIO
Supported field types for forms are: - Text (single or multi-line) - Numeric (plain, with +/- buttons or with slider) - Date / time (with calendar picker) - Photo - Checkbox (yes/no values) - Drop-down with predefined values - Drop-down with values from another table

Comments on Mergin Maps: QGIS in pocket for Android
★★★★★Edip Ahmet TAŞKIN· Apr 14, 2019
Very stable and usable for field works. The app can open and visualize GİS data faster compared to other GİS apps.
★★★★☆Joshua Gottdenker· Mar 19, 2022
The app is simple and easy to understand, that's great. And it's free, but the description promises export and interoperability with qgis. This seems to ONLY be possible via the open source online mergin service. I expect the app itself to be able to export the field data without synchronizing it through a service. (My apologies to the team for assuming that mergin was proprietary, and thanks for your generosity to release it open source! )
★★☆☆☆Mark Glover· Nov 11, 2024
Unable to load layer files on device Mergin is not compatible with QGIS
★☆☆☆☆Marie Geneste· Nov 18, 2022
Authentication critical bug. Can't sign in as log in password created on web app doesn't work on native app.
★★☆☆☆Scott Hawken· Aug 6, 2025
I misunderstood what the creators meant when they said built on the free and open access QGIS - the app isn't free. If it was I'd give it 5 stars as it is it's not a pass for me - I'd have tried something that advertised accurately.
★★☆☆☆Dylan Clark· Jun 16, 2025
Can't upload a GeoTIFF from the device which is pretty basic stuff.
