Orthophotos show some holes Question
« on: October 16, 2021, 09:27:23 PM »
Have a question about holes on a few orthophotos after I export Orthomosaic.

When I build an orthomosaic, I can see no problems at all  BUT...

When I review each orthophoto, I found a few holes and wonder why what can cause that ?

I have been trying to figure it out how to fix it but no luck.

When I use orthomosaic the settings I set are follow as :

Coordinate System : NAD83/ UTM zone 13N (EPSG:26913)
Rater:  Leave as Pixel Size (m)
Region : Leave as Total Size (pix)

Enable Write title Scheme:
Compression   TIFF compression as Deflate
JPEG Quality as 90
Enable as Write tiled TIFF
Enable as Generate TIFF overwrite

Use JPEG 2000 to export both orthophotos and Orthomosaic




Same area overlaps.

When I export orthomosaic and show the same as orthophoto I show you does not have holes.



Do you know what may be causing it ?

Thanks

Well well ,  Problem solved !

Had to fix the tie points in that area but most importantly to get clean is to build mesh .

This did the trick to get them the holes disappeared.

What do you mean when you say that you had to " fix the tie points"?
