# Supported Formats

When working with Mergin Maps Input, you can keep using standard data formats you are used to in QGIS. In general, most of the data formats that QGIS can load, can be also used in Mergin Maps Input. There are however some minor differences worth highlighting.

# Vector data on Mergin Maps Input

For survey layers used on the field, we strongly recommend GeoPackage, to be able to work fully offline, benefit from automatic merging of data (collaborative editing) and versioning.

Format Android/iOS Note
GeoPackage 😍 collaborative editing and versioning by geodiff (opens new window)
Shapefile ⚠️ collaborative editing not supported
Delimited text ⚠️ collaborative editing not supported
Virtual layer ⚠️ collaborative editing not supported
PostGIS 👍 requires internet connection
WFS ⚠️ requires internet connection (open ticket (opens new window))

There are more formats supported, please see full list of supported QGIS providers and OGR drivers

# Raster data on Mergin Maps Input

Format Android/iOS Note
GeoTIFF 👍 jpg and webp compression
COG (local) 👍
MBTiles 👍 png, jpg compression
GeoPDF 👍
WM(T)S 👍 requires internet connection
XYZ tiles 👍 requires internet connection (e.g. OpenStreetMap)
COG (online) 👍 requires internet connection
ECW 🚫 proprietary license
MrSID 🚫 proprietary license

There are plenty of other raster formats we support through GDAL/OGR, please see the full list


See our guide for setting up background layers.

# Vector tiles on Mergin Maps Input

We support vector tiles just like QGIS does - in Mapbox Vector Tiles (MVT) format - and stored either in a MBTiles file (for offline use) or through a template URL (for online service) such as http://example.com/{z}/{x}/{y}.pbf.


See our guide for setting up background layers.

# How to convert between GDAL/OGR formats

To convert between various GDAL formats, you can use gdal_translate (opens new window) command-line utility.

# Support for new formats

If you find out that the Mergin Maps Input doesn't support your format, please open issue at lutraconsulting/input-sdk (opens new window).

If QGIS on desktop does not support the format of your choice, open issue at qgis/QGIS-Mac-Packager (opens new window) for macOS, or qgis/QGIS (opens new window) for other platforms.

For support of collaborative editing and versioning of vector data formats, please open issue at lutraconsulting/geodiff (opens new window).
