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

Just what I was looking for. Easy to record data in the field, uploaded once able to and then downloaded to my own files, opened the QGIS file that was created and all the data was there. It would have been useful to have created new layers out in the field, but I believe there is a way to set this up from QGIS originally to allow this. I used the text fields for all data as the number field is integers only and the check box is true/false only... But text works well anyway. Really impressed.

Great ap very easy to use and install and compatible with many GIS systems. I am using it to survey and map extent of invasive species across a catchment. Often chatting to landowners at the same time and have been able to map and chat simultaneously. I contacted Lutra regarding licencing and had a positive response within the hour. Excellent customer service. One star lost due to occasional stability issue, always resolved by restarting the ap without any data loss.

In case of 10 or more people parallely trying to sync data. Some times it drops some data. Same with photo attachments. So if u intend to use it for a data intensive field survey, I suggest look for more robust apps with dynamic and fast data sync as normal DBMS works. However it's ease of creating mobile surveys using GIS data is really a great feature for non coders.

Great field survey app linked to a Cloud through Mergin. As a peatland restoration programme we conduct field surveys in the uplands of Autumn and Winter in the UK. We are quite frequently exposed to extreme weather conditions and gloves are required. With a stylus, I note that you can double tap the screen to zoom in, however this often highlights a layer and is sometimes intermittent. It would be fantastic if you could add in a zoom in/out function on the display. Thanks, Ollie

You can create incredibly sophisticated data collection apps that you can take offline (or online), and then sync with your QGIS project. Supports multiple users all syncing to the same project through the online interface and cloud data storage. Everything is open-source and there is a generous free tier for data storage that satisfies personal and educational projects. I've been using this app for a few years and it has proved stable and is under active development.

I have nothing but good things to say about Mergin. I am using it for a large number of projects and it is working extremely well. It is simple, easy and it really delivers. It has been an absolute lifesaver for collecting data out in the field especially with its offline capabilities. I have also had great experience with their support as they return emails very quickly providing detailed information on possible solutions to any small problems I have had.

This app has really helped our loader operators work in an area with sensitive boundaries only visible on the map. The app is extremely easy to use but can also take advantage of advanced QGIS capabilities. Whether you're new or experienced, in whatever industry, there is probably a solution waiting to be taken advantage of the usefulness of Input.

Really nice interface and features. I'm having just one issue at the moment, when typing in information longer than the box I can't see what I'm typing because it doesn't follow what was last typed. I can only see what I have typed if I scroll to the right manually, is there a fix for this?
