Private map library
Upload PMTiles, inspect boundaries and metadata, manage your quota and delete files you no longer need.
Field journal and offline map service
Choose historical maps, create offline OSM regions, georeference your own scans and send everything to Android. In the field, THS2 records routes and finds without requiring a network.

Available now
The web service prepares and stores maps, Android brings them into an offline catalogue, and the field journal keeps working where connectivity does not.
Upload PMTiles, inspect boundaries and metadata, manage your quota and delete files you no longer need.
Search by a point on OSM, compare coverage and samples, then add free maps to your library.
Choose an area and zoom level; the server safely prepares a vector PMTiles map for offline use.
Match points on a scan and OSM, preview the result over a modern map and create your own PMTiles.
Sign in from the app and download maps with progress indication and secure resume support.
GPS tracks, quick finds, photos, the Home point and trip exports remain available offline.
One ecosystem
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.
Android · 0.2.0-alpha06
You can test active trips, GPS tracks, quick finds, local PMTiles and account downloads. This is an early testing build, not a final release.
Six pinned types plus fast photo and marker actions.

Track and points take priority while critical actions stay close.

THS2 · web service
The web service at ths2.ru already works as a companion to the mobile app. It extends the autonomous field journal with a private library, PMTiles preparation and secure delivery to the device.
Account-based PMTiles upload and viewing, protected downloads and a clear personal storage quota.
Choose an OSM region or georeference your own raster scan with control points; the server prepares the PMTiles file.
Public cards, previews and geographic search are available. Free maps can be added to a library; payments are not yet live.
Transparent development
Development moves through verified stages. Each stage starts only after the previous one is tested, so data reliability never becomes an afterthought.
Email verification, password recovery, personal quotas and a protected API.
PMTiles upload and validation, previews, geographic search and free map acquisition.
Authentication, profile, available map listing and resumable delivery into the app’s local catalogue.
Control points, result preview and server-side PMTiles generation are undergoing practical testing.
Android field trials, stable map processing and only then payments for paid materials.
Current app stage
The current focus is raster georeferencing, reliable large uploads, Android map downloads and real field trials. The free map catalogue and personal libraries are already open to users.
Open catalogueIn the MVP, the database stays on your device. Exact coordinates, photos and notes are not sent to a server without an explicit action from you.
