ImageStation® Automatic Triangulation (ISAT) is an automatic image point
extraction and triangulation package that delivers the best-matched multi-ray
tie points by using robust built-in bundle adjustment during all phases of the
image matching operation. ISAT provides footprint selection that lets you
graphically select footprints of photos/models/blocks, unlimited project size
using sub-blocks, GPS/INS data processing, seamless Applanix POSEO support,
camera calibration, automatic parameter selection and analysis for self
calibration, graphical vector analysis, and more. ISAT provides fully automated
aerial triangulation from interior orientation to the determination of tie
points to the final block adjustment analysis with delivery of orientation
parameters.
ISAT is a very flexible and powerful product for today’s high throughput
aerial triangulation applications. This product is built on top of the
ImageStation Digital Mensuration (ISDM) product. All ISDM features are
accessible in this product.
