High Quality and Complete 3D Coordinates

- Perfect 3D coordinates achieved by 3-way observation

PRISM data acquired by 3-way optical system (Forward, Nadir, Backward) makes highly accurate data of various types of terrain, even sharp slope of Mt. Everest. True Ortho is orthorectified imagery made from nadir image without angle view. Highly accurate 3D coordinates information is available using 3-demensional information (DEM and orthorectified imagery) including horizontal information.

- High Geolocation Accuracy without GCP Correction

The product offers high geolocation accuracy without any ground control points, thanks to the precise position/attitude data of the sattelite and well calibrated sensor models. Moreover, it is equipped with high data quality which does not include any systematic noise derived from the satellite observing system such as an attitude jitter by using high-frequency attitude data exclusively used for this product.

2m resolution Enhanced 3D Topographic Data

Enhanced 3D Topographic Data with 2m resolution is our newest and highest resolution product. It achieves 2m spatial resolution with 2m vertical and horizontal accuracy (with GCP) using DigitalGlobe imagery. Enhanced 3D provides terrain models with such high resolution that detailed variations in building heights can be determined.
