No aerial photo? No problem.

Not every roof is clearly visible on the map. New construction, recently renovated buildings or locations with outdated aerial photos? You can always get started right away. Draw the roof yourself based on building plans or dimensions, or upload a drone image for an up-to-date overview. This way you create an accurate and clear layout plan for every situation.
