Mapping Residential Estate for Inventory and Management

I have searched the forums for answers but found only partial answers to my very simple question. What are the correct and best settings to map a residential estate for inventory and management. Let me explain - we need to map the estate in full (houses, roads, walkways, gardens, trees, manholes, electrical sub-station and connecting boxes, streetlights, benches, perimeter fence, cameras, stop streets etc. for the purpose of infrastructure inventory and a map for planned maintenance of the infrastructure. It will also enable estate management to identify illegal additions and structures on the estate. We don't need full 3d but we do need high resolution quality to zoom into any area for inspection purposes. The map should be able to be printed out and also uploaded to a website for promotional and marketing purposes, but also be available electronically for inspection purposes. It may seem simple but I have only flown a few Map Pilot mapping sessions and learned a lot the hard way. I don't want to screw this up as the area area is 35,2 hectares (87 acres) and will require me to fly 3 missions with my P3S, one after the other. Residents are co-operative, but it will be a problem if I fly too many missions. Highest structures are 40m AGL. What hight, speed, overlap and procession option do you suggest? Regards and Thanks

The best and easiest way to shoot something like that would be to use the Map Pilot defaults of Auto exposure and 80/80 overlap. If the highest structure is 40 meters you would need to fly 4-5X that height, which might be too high. Look into using Terrain Awareness to minimize the height you have to fly while still being 4-5X the height of the roofs. If you can't fly that high you will need to use a bit more overlap or you risk not being able to render the highest spots.

Use the DJI Specific workflow with the default settings. 

Also, the P3S isn't the right tool for the job. You can try it but that camera is almost 7 years old at this point. You will save a lot of work and get better results with a more modern aircraft/camera.

Thank you. I will fly a test area with the suggested settings. The P3S is brand new out of the box and I will have to use it and make the best of the suggested settings.
