ImageStation Automatic Triangulation

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.
