Numbers on the Survey Data

[Toshi_OK]

Hi Everyone,

Could someone let me know the exact meaning of the numbers on the Survey Data?

According to the PhotoScan manual, it tells the data includes overlap statistics, as in below

• Survey data including coverage area, flying altitude, GSR, general camera(s) info, as well as overlap
statistics.

So I think the numbers would be the overlap statistics. However its unit?
For example, if the area is the blue ( > 9), is the area made by more than 9 pictures? or overlapped more than 90%? or something else?

I appreciate for any suggestion and confirmation.

Thank you!

Hello Toshi_OK,

It's about the number of images. Blue color means that the area is seen from more than 9 photos.

Hi,

I want to get clarification about the 'overlap' concept.
In the processing report, it can give you the image overlap estimation of your final ortho-mosaics. If the number of "overlap" image is 9, is that means all the points within the area have shown in at least 9 photos that have been originally taken?
Hope to get your idea and thank you for your time.
