Motivation• To produce a portable & simple-to-use and stereo product

– Geotagged, e-form, hardcopy

• Criterion– No use of DEM, Quick TAT, No internet, Indigenous development

• Applications– Mission planning, Field correlation, Navigation

• Problem– To process the stereo pairs for epi-polar registration

TARGET PRODUCTS / SOLUTIONS

DEM, DSM ½ arc-second posting

ORTHOIMAGE 2.5m resolution or better

OPPORTUNITIES

WORKFLOW OUTLINE

TerraBlock : Indigenous Development

• ‘Stitches' multiple scenes• Computes refined RPCs• Uses minimal control• Carto-I and II,GeoEye• Mono / stereo
