I'll be doing a webinar next week on mosaicking, which was just announced on the ERDAS web-site yesterday. The main focus will be planning considerations for frame photograph mosaicking, processing techniques (radiometry, image manipulation, seams, output considerations), and final mosaic product generation. This may be of interest to both LPS and ERDAS IMAGINE users (along with anyone generally interested in mosaicking), since I'll be using MosaicPro for the processing: an add-on module to both LPS and IMAGINE.
The registration page is here. We'll be hosting the webinar at both 3AM and 11AM EST, so please feel free to join us for either session!
