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.

You are currently browsing repository for Mergin Maps web server and web client. Our mobile app, QGIS plugin and integrations have standalone GitHub repositories, you can find them here.

Features

• 🌍 Store data - GeoPackages, QGIS project files, GeoTIFFs, pictures or any other data easily
• 📱 Mobile devices - Great for working on field surveys, thanks to our mobile app based on QGIS, for iOS and Android
• 🌟 QGIS integration - Mergin Maps plugin is available to help with project setup and seamless syncing within QGIS
• 👥 Multi-user editing - Changes to vector/attribute data from multiple users are automatically merged
• 📖 Data versioning - Keeping history of all changes, allowing to go back if needed
• 🔌 Offline editing - Clients do not need to be online all the time - only when syncing changes
• 🌱 Sharing with collaborators - Projects can be shared with other team members
• 🏰 Permission system - Decide who can read, write or manage projects
• 🌈 Web interface - Simple user interface to view and manage projects
• ⚡️ Fast - Efficient sync protocol transfering data between clients and server
• 🧑‍💻 Developer friendly - Mergin Maps is open platform. CLI tools and client libraries are available for Python and C++
• 📷 Sync images - Supporting sync of photos with common cloud storage using mergin-media-sync tool
• 💽 Sync with database - Supporting two-way sync of data with PostGIS using mergin-db-sync tool
• 👷‍♀️ 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.
