Exporting Orthophoto

[Elaigwu Oseni]

Dear all, kindly assist. I have been trying for hours to export a built mesh model to orthophoto in geo-tiff format. At the end of processing, I get the message "Can't export orthophoto". Although there's  a .tif file on my photoscan project folder but the file is not readable on ArcMap. Thanks in advance

Hello Elaigwu Oseni,

Do you have Console pane information related to the export process saved?

Probably the reason of the problem is the file size, as at the moment PhotoScan cannot export individual TIFF file with the size greater than 4 GB.

Thank you Alexey for the quick reply. I do not have screenshoots of the export process but the total size (pix) is about 60000x57000 and the existing .tiff file created has a size of 3.9G. From experience, to have minimum number of mosaics, which block size will be best to split orthophoto. Thank you

Hello Elaigwu Oseni,

For TIFF file such resolution seems to be larger than 4 GB (for minimal empty area).

I can suggest to use blocks of 25 000 x 25 000 size or something about that.

In principle, you can try to generate 4 blocks for the existing data, taking half from each dimension.
