Field journal and offline map service

Maps for the field. Your data under your control.

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.

A complete map journey — from archive to phone

The web service prepares and stores maps, Android brings them into an offline catalogue, and the field journal keeps working where connectivity does not.

01

Private map library

Upload PMTiles, inspect boundaries and metadata, manage your quota and delete files you no longer need.

02

Historical map catalogue

Search by a point on OSM, compare coverage and samples, then add free maps to your library.

03

Offline OSM regions

Choose an area and zoom level; the server safely prepares a vector PMTiles map for offline use.

04

Raster georeferencing

Match points on a scan and OSM, preview the result over a modern map and create your own PMTiles.

05

Delivery to Android

Sign in from the app and download maps with progress indication and secure resume support.

06

Field journal

GPS tracks, quick finds, photos, the Home point and trip exports remain available offline.

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.

THS2 · web service

Prepare maps on the web. Use them in the field.

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.

Web service is live
01

Private library

Account-based PMTiles upload and viewing, protected downloads and a clear personal storage quota.

02

Map creation

Choose an OSM region or georeference your own raster scan with control points; the server prepares the PMTiles file.

03

Map catalogue

Public cards, previews and geographic search are available. Free maps can be added to a library; payments are not yet live.

Transparent development

What works today

Development moves through verified stages. Each stage starts only after the previous one is tested, so data reliability never becomes an afterthought.

01
Complete

Accounts and secure access

Email verification, password recovery, personal quotas and a protected API.

02
Live

Map library and catalogue

PMTiles upload and validation, previews, geographic search and free map acquisition.

03
Complete

Android integration

Authentication, profile, available map listing and resumable delivery into the app’s local catalogue.

04
In progress

Raster map georeferencing

Control points, result preview and server-side PMTiles generation are undergoing practical testing.

05
Next

Testing and store launch

Android field trials, stable map processing and only then payments for paid materials.

Current app stage

Validating the full path from a map to field use.

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 catalogue

No mandatory account

In 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.
