Orthoimagery Mapping

Good evening everyone,

I have a few questions regarding a recent flight planning. Due to a planning error, some areas were left without photographic coverage. I believe that only a small number of images are missing.

My question is: is it possible to plan an additional flight to capture only those specific missing areas? If so, does Maps Made Easy allow reprocessing the orthophoto by adding only the new images, or is it necessary to perform a completely new flight and reprocess the entire orthophoto from scratch, losing the existing one?

I have a second question related to flight planning and image processing. I am planning a flight for a relatively small property that is divided into two separate blocks. The first block is close to the house and covers approximately 6 hectares. The second block is within the same property, but the drone must travel about 1.3 kilometers to reach it, covering the remaining 60 hectares.

My question is the following: when using a DJI Air 2S, all images are stored on the microSD card and later downloaded for processing. When creating a new map, will the software automatically process all images together correctly, even if the distance between both blocks is significant? Or would it be recommended to process each block separately to avoid alignment or accuracy issues?

Thank you very much for your support and recommendations.

It is REALLY hard to patch an area with images taken at another time. The only way to get it to work is to revisit the spot at the same time of day with the same lighting conditions. You would also need a few passes of extra overlap to help tie it in. 

Another option is to just do the area that was missed and then combine the images using a Location Map or GIS software. 

If the two sections you are trying to cover are not actually touching (contiguous) they should be run separately. If you run them together one of them will be deemed out of the allowable error spec and the images will be dropped.
