Creating an area
The map view offers three ways to create an area:
“Draw area” is for the desk. Tap the corners on the aerial image.
“Walk the corners” is for fieldwork. Go to each corner and tap “Set corner here” there.
“Walk the boundary” is for areas with many corners. Walk along the edge. The app sets a point every 8 m.
While you walk, the screen stays on so that location tracking does not stop. Avoid switching to another app meanwhile.
Draw a hedge as a narrow strip, about 150 × 5 m.
You can move corners later in the area with “Move corners”. A walked area then loses the note “recorded on site with GPS”.
Plan planting
Which tree species suits which place is normally judged by an expert on site. The “Plan planting” button in the area reproduces part of this assessment. The app retrieves altitude, slope, aspect and climate (today and around 2050) and combines them with your information on soil, moisture and deer. From this it suggests tree species with reasons and states the number of plants, protection, planting time and collection date. You can overwrite any value.
Count survival
Under “Survival” in the area, enter during the inspection how many plants of each species are still alive, or the share from a few sample plots. From this the app calculates how much has survived and failed and, with the mean height from two counts, the growth per year. In the next planning on this area and on areas nearby, the counted share appears under the species.
Collect guards
The “Collect guards” tile in the “Tasks” tab counts the guards and stakes still standing in the forest. Material that rots in the forest is not counted.
When collecting, the app counts guards, stakes and, for fences, mesh and fence posts, each with its own counter. If you pull out guard and stake in one go, select both counters at the top. Then one press counts both.
On “Only collect guards” areas, the counter also counts the stock. Select “Stock in the forest” at the top and, as you walk the area, count the guards still standing. This gives the total.
Data server
Treemulator needs no server and no accounts. Each device stores its own data, and the app works in the forest without a network. That is why data is not synchronised automatically and two people cannot edit the same area at the same time.
Areas, guards and tasks only leave the device if you share them yourself. The map images, however, come from third-party services. These receive your device’s connection data with every request. The privacy policy lists which services they are. Links to the providers are in the legal notice.
Recommendation for a forestry operation: Each person keeps their own areas and sends them on, for example after a walk through the forest. One device collects all areas, usually that of the district manager. Everyone sends their areas there and receives the complete set back from there.
With your own server, for municipalities and forestry operations: A version with its own server is possible, for example on a server of the municipality. The devices then synchronise their areas automatically as soon as they have a network. In the forest they keep working without a network. The data is then also stored on this server. This version is developed on request. Requests to the operator of Treemulator: info@treemulator.org. The privacy policy states how long requests are kept.
