I’m new to DD. Today I got a question of a potential client (large real estate investment company). They will compare walls, roofs, … over multiple years. To reduce inspection/maintenance cost, it would be very interesting to get differences in time marked on the picture/map. So, I’m searching for a good solution.
Hi @DrPa,
Welcome to the DroneDeploy Forum. I hope you’ll find this space useful as you continue learning about and using the product.
Currently, this feature is not available but we do plan on implementing change detections in the near future. However, we have a free app available in our App Market called Side by Side that will allow you to compare differences that occur over time in maps that are of the same area.
Hope this helps. 
Cheers,
Christina
