Satellites orbiting the globe have orbit elevations and time intervals to cover and image the same area.Īerial triangulation is a method for producing maps by overlapping aerial images. Aerial triangulation scans are digital aerial photos of B.C. We describe our automatic generative algorithm to create street addresses from satellite images by learning and labeling roads, regions, and address cells.

Aerial imagery covers a smaller territory but has a better resolution. Satellite imagery is a critical tool for visualizing ground conditions. High-resolution images are useful for mapping, research, emergency planning and natural resource management.
