About

Mergin Maps is a web platform for storage and synchronisation of geospatial projects across multiple users and devices (desktop and mobile). The platform is especially useful when you need:

• Mobile data collection. If you need to capture location of assets (and their attributes) or update an existing database.

• Data sharing. No complicated setup of access by IT admins to get your data to colleagues or clients. Set up permissions and send invites with few clicks.

• Offline access. Work with data with no interruption even without constant Internet connection - sync any changes when you are back online.

• Collaborative editing. No more problems dealing with multiple copies of the same dataset in different versions - all changes are automatically consolidated in one place.

• Audit changes. Knowing who has changed what and when in a database is often important - Mergin Maps keeps track of the history and allows to go back if needed.

• No coding required. Everything can be set up with no knowledge of programming.

Mergin Maps organises all data in projects. A project in Mergin Maps is a directory containing various data files - GeoPackages, QGIS project files, documents, pictures and more. As soon as a project is uploaded to Mergin Maps, it can be easily accessed directly from the web, from QGIS or from iOS/Android via our mobile app.

• 👷‍♀️ Work packages - Split main database to smaller chunks for teams using mergin-work-packages tool

Mergin Maps offers a unique combination of features that other tools do not provide out of the box:

• relational databases (such as PostGIS or Oracle) are great for keeping a central repository of spatial data, but offline access, versioning and sharing outside of a single organisation are complicated to set up.

• traditional storage products (like Dropbox or Google Drive) are great for storage of large amounts of data (pictures/videos) and offering offline access, but concurrent access to data (e.g. a single vector layer) is not going to work well.
