A web map and the map inside the Sysel mobile app for forest managers, which we designed as a team and I built: your own forest management plan (LHP), cadastre and orthophoto, drawings from the field and tasks with a deadline.

Mapy is a tool for forest managers that runs in the browser and inside the Sysel mobile app. The forester sees the stands from their own forest management plan (LHP), orthophoto, cadastre and other public maps (ÚHÚL, LČR, LPIS). They draw areas on the map and create tasks from those drawings.
We designed the map as a team and I built it, including the part of the WoodSoft backend for drawings and tasks. It is sold publicly as Sysel pro lesní hospodáře (Sysel for forest managers).

A company gets its forest management plan (LHP) as a ZIP or XML file. It is uploaded to the web, and a few minutes later the plan is visible on the phone and on the computer as a map with stands, felling and management measures. Each stand has an extract from the stand register. The map is not redrawn on every pan: the finished tiles are prepared in advance and the server just hands them out, so the plan opens quickly even on a phone.
There is often no signal in the forest, so the forester downloads the area beforehand and the map, orthophoto and cadastre keep working. The downloaded area stays in the phone, also in the map inside the Sysel app. Drawings made without a connection are sent as soon as the phone is online. The tiles are stored directly in the phone's files, because the browser storage in iOS turned out to be unreliable.
A forester in the field draws an area, for example a clearing or a fenced plantation, and the office turns it into a task with a deadline. The task is assigned to a colleague, a contact from the address book or anyone else by link or SMS. The assignee gets the place and navigation, the task status changes in the notes history, and the finished work is confirmed with a photo and a note.

The map runs in the browser and inside the Sysel app and is drawn natively in S-JTSK; the server hands out ready-made forest plan tiles from a cache, the WoodSoft backend stores drawings and tasks, and a downloaded area stays on the phone for work without signal.
I describe how I build systems like this on the How I work page.
