Ortomosaic with blank raster cells

PeterLarsen — Mon, 15 May 2023 07:34:27 GMT

Incomplete mosaic over lake. Raster cells around the hole is blurry.

I have tried to change the settings, but the blank cells appears anyway.

Anyone who had the same error and has a solution?

Lakes can be difficult, tried addressed with water body mask

Hi @PeterLarsen,

Sorry I missed your email I was out sick last week. I saw you posted here on the community forums as well and the image you shared here provides me with a bit more insight to the reconstruction issues going on with the project.

Looking at the flight lines and image collections for the flight there doesn’t seem to be any uniformity. By this I mean that the overlap between images is very erratic and there are large gaps between image collections. Is this how the flight was flown or are you missing images from the flight?

If you are missing images that Drone2Map didn’t import then we can attempt to look into why. Otherwise, my suspicion is the hole is being cause by poor overlap between images. If you look at the processing report for the project and review the graphic that depicts image overlap do you also see a hole there?

Regards,
Mark

It worked with water body mask and processing it again. Thanks for the help
