From source map to field use
Convert and validate maps in the browser, download them to Android and keep a field journal offline. An account and cloud storage are only needed for the features you choose.
Library and cloud storage
Upload PMTiles, inspect boundaries and metadata, manage your quota and add more storage only when needed.
Converter and georeferencing
Turn rasters, KMZ and XYZ/TMS archives into PMTiles or align scans to OSM with control points.
Offline OSM regions
Choose an area and zoom level; the server safely prepares a vector PMTiles map for offline use.
Historical map catalogue
Search by a point on OSM, compare actual coverage and samples, then add free maps to your library.
Android and backups
Resume map downloads, open PMTiles and KML, and create encrypted backups locally or in your account.
Field journal and feed
Keep GPS tracks and finds offline, then share selected stories in a moderated feed with likes and awards.
One ecosystem
Prepare a map on the web. Take it into the field.
The website and app handle different parts of one workflow. Heavy processing runs on the server, while the maps and field data you need remain available offline on your phone.
Catalogue maps are stored once on the server. Your personal quota is used only by files you upload or create yourself.
