About GEOSPAN

GEOSPAN is the provider of the technology leading spatially accurate GEOVISTA® Multi-Angle Imagery™ and GEOVISTA® 3D Spatial Imagery™ products. GEOSPAN patented technology offers fully integrated high-resolution 360º oblique aerial and street-level GEOVISTA® imagery. GEOVISTA® panoramic imagery solutions support a variety of state and local government GIS applications including E9-1-1, emergency management, homeland security, law enforcement, planning, property assessing, infrastructure inventory, pavement analysis, and transportation. GEOVISTA® solutions also serve a variety of private sector markets including real estate buying and selling, visual mapping, insurance, mortgage lending and micro marketing.

The use of multiple data sources also overcomes shortcomings of single source solutions. Data collected from different sources can be cross-referenced that will significantly reduce the uncertainty on data quality and eliminate inconsistency when data are collected from uncoordinated data acquisition activities. The multi-technology solution can also reduce the need for field surveys, which has safety benefits not only to data collection agencies, but to the traveling public. Different vantage points using multiplatform remote sensing, particularly the combination of overhead views and terrestrial views, can address data collection problems associated with limitations of a single view point. That is, satellite imagery and aerial photography can provide images from 7 overhead that cover areas far beyond roads, while vehicle-based mobile mapping systems can bring out images behind trees or under bridges.
