Approach
- Obtained a dataset of forest types (needle-leaf, broadleaf, mixed, etc.)
- Filtered out the types that are typically not suitable for mushrooms to grow in
- Obtained a list of paths and trails from OpenStreetMap and generated a distance field around them
- Superimposed the trails and distance map on the forest regions of interest
Result
The final map shows the forest regions that are suitable for mushrooms to grow in and the distance to the nearest path or trail; the idea being that the further away from the path you search, the less likely it is that someone else has already found and picked the mushrooms.
