Hello, thanks for mapping on this project.
A remark. Please focus on the objects which has to be mapped: Buildings and roads.
Grassland is not a part of the instructions. As a matter of fact, it is not usefully to map those area subjects in the tasks of a HOTOSM project. These kinds of areas are always mapped outside HOTOSM projects. A bit weird. Now you have a square tagged as grass, the surroundings, same situation, not.
I removed those mappings.
Best regards and focus on the goals of the project.
