The map

What Oma Tienoo draws of the forest

The map always has one base map, and over it as many layers as you want. The layers answer different questions, and each has its own page saying where the data comes from and what it does not promise.

Mushroom maps

The chanterelle prediction layer on the Oma Tienoo map: suitable forest stands colored in

Six species, six kinds of forest. A layer colours the stands where a species does well.

Conditions

The conditions layer over southern Finland: the map coloured from red to green by rainfall

The whole map red to green by where the conditions are best right now.

Upcoming fellings

The felling layer on Oma Tienoo's map: forest use declaration stands coloured over the terrain map

The valid forest use declarations. A declaration is not a felling, and the page says what it is.

Registration units

A registration unit boundary drawn on the topographic map, with a panel below showing the unit number

Tap the map: the register names the unit and draws its boundary.

Base maps

The map layers sheet open, showing the six base map options as a list

A background map, a topographic map and three aerials. Choose before you download an area.

Six species

Each species is its own layer, and each has a page saying where it grows and when it is worth looking. Season weighting fades a layer where the species is out of season or the ground is dry. Most promising areas lists the best areas for a species within a drive time you choose. How the prediction is calculated and where its limits are: the mushroom maps and their limits.

The same data from the forest side

Once you are in the forest the question turns round: what is worth looking for here. Forest types gathers the same model into three types you can recognise on the ground, and names the species of each.

Every layer is in the same place in the app, behind the Karttatasot button at the edge of the map. The guide covers getting started.
