Mergin Maps: QGIS in pocket APK

Mergin Maps is a powerful, open-source field data collection tool built on QGIS—designed for surveyors, environmental scientists, engineers, and GIS professionals. 

Seamless Operation

Setting up your project is quick: create your survey in QGIS, connect it using the Mergin Maps plugin, and sync it to your mobile device. You're then ready to collect data on points, lines, and polygons, complete forms, and track your live location in the field.

Easy QGIS Integration

Mergin Maps lets you transfer your QGIS projects to your mobile device with just a few steps. Your layers, symbology, and forms remain intact, so you see your map exactly as it appears on your desktop.

Offline Field Data Collection

No internet? No problem. Mergin Maps supports offline data capture and offline basemaps, ensuring you can still work in remote areas without a network connection.

Real-Time Sync and Collaboration

Push data back to the server as it’s collected or sync later when you're online. Multiple surveyors can collaborate on the same project, and updates are merged intelligently with version control and cloud-based backup.

Advanced Survey Capabilities

Capture data using customizable form fields including text, numbers, checkboxes, date/time pickers, dropdowns, and even photos. Mergin Maps also records metadata like EXIF and GPS details for precise documentation.

High-Precision GPS Support

Need accurate positioning? Connect an external GPS/GNSS device via Bluetooth and enhance your data quality for professional-grade surveys.

Export to Multiple Formats

Data can be exported to CSV, Excel, Shapefile, GeoPackage, KML, PostGIS, AutoCAD DXF, and more—making it simple to integrate into your existing workflows.
