The scanned images are currently being transferred from tape to CD-ROM and uploaded to the workstation's mass storage. Aerotriangulation will be completed by November 30, 1996. The digital photogrammetric system will automatically produce very dense grids of elevations in the overlap area of each pair of photographs. These must be edited to correct errors and resolve ambiguities encountered by the image correlation algorithm. Features of interest will be extracted from the stereo models by operators with some assistance from line-following algorithms.
Fieldwork is currently underway to obtain precise coordinates and elevations of selected features.
This will enable early fine-tuning of the compilation process and ensure quality control throughout our procedures and products. The orthophotograph will be completed by June 30, 1997. The project's final report will be available shortly thereafter. Ever since, project status has been a frequent topic of discussion in that seminar. The project has been presented to a variety of potential technical stake holders and professional organizations.
