This mapping process of planimetric or topographic data in a 3-D environment from two overlapping images allows for the precision accuracy collection of both vertical and horizontal coordinates. After overlapping two images, vector data is collected in house by our own stereo compiler specialists in order to produce a product with real world vertical and horizontal accuracy.

This data set can then be utilized with ortho products for the use of slope analysis, hydrological studies, agriculture and land planning, urban development as well as the assessment of impervious surfaces and new infrastructure.
