Need to rectify many old aerial photos ?

Recommended Posts

Which one do you recommend me to use ERDAS AutoSync or  Photogrammetry  to orthorectify  many old aerial photos ?  I have about 600 of them.

The aerial photos I have do not have georeferenced.

PCI Geomatics may be the way to go, as it has a module that handles old aerial pictures

first, since you have so many data, you need a batch process to do that.

erdas autosync is good since you need to make a lot of geo-referencing data also

I think you need combination of software

Thank you everyone. My employer only has ERDAS, so I have been using AutoSync lately and got to learn and dive into it and it is really great software to use.

Regards !
