The resolution of arrows can vary according to the size of the site, as well as the topography file being used. This resolution depends on the area of the topography mesh extracted from the source.
For Google Earth data, the resolution of the arrows is:
- 5 meters if the mesh area is less than 20 ha
- 10 meters if the mesh area is between 20 & 50 ha
- 15 meters if the mesh area is between 50 & 500 ha
- 20 meters if the mesh area is between 500 & 1000 ha
- 30 meters if the mesh area is between 1000 & 2000 ha
- 60 meters if the mesh area is between 2000 & 3000 ha
- 90 meters if the mesh area is more than 3000 ha
The resolution of the arrows for custom data is:
- 2 meters if the mesh area is less than 20 ha
- 3 meters if the mesh area is between 20 & 50 ha
- 5 meters if the mesh area is between 50 & 100 ha
- 10 meters if the mesh area is between 100 & 200 ha
- 15 meters if the mesh area is between 200 & 500 ha
- 20 meters if the mesh area is between 500 & 1000 ha
- 30 meters if the mesh area is between 1000 & 2000 ha
- 60 meters if the mesh area is more than 2000 ha
