PHOTOMOD 5. Project ManagementPHOTOMOD 5. Project Management

Large block support (over 20 000 images)

Speed up global block operations

Integration of AT and Solver to speed up aerotriangulation, locating and correcting blunders

Several graphical modes No graphics—for huge blocks

(recommended for blocks over 5000 images) Limited graphics—for large blocks

(recommended for blocks of 1000—5000 images) Full graphics—for medium size and small blocks

(recommended for blocks up to 1000 images)

Override of fixed stage sequence while retaining clear workflow

Ability of stereoprocessing before completing triangulation

Stereoprocessing of any two overlapping images
