Delete or Moved a or few markers AFTER you orthomosaic ?
« on: August 21, 2020, 09:09:27 PM »
Question.

Whenever you deleted or moved a  or few marker(s) after you build an orthomosaic, do I need to go back to Workflow  again from the beginning ?

or do I need to start from one of these following ?

Build Dense cloud
Build Mesh
Build Texture
Build DEM and finally
Build Orthomosaic ?

So if I am correct or not ?



Sorry I am not explaining myself clearly on why I am asking is because  I am still working on old aerial photos from 1930's and sometimes
I need to fix some bad markers that need either move or delete...

These aerial photos I have are within the national forest boundary and they do not have metadata and it lacks the information when it was flown.

They were scanned from one of our contractors that did for our forest....


Thanks

As markers (GCPs) affect the tie-points and internal and external parameters of the images, which in turn affects the dense cloud, which affects the mesh and thus the orthomosaic - it is necessary to go back to the Build Dense cloud after adjusting the markers. It is also necessary to either update or optimize your project after making any adjustments to the GCPs.
