Current Market Trends
• Managing geospatial imagery remains problematic. Despite cheaper storage and
increasing processing power, imagery is continually captured
• At higher resolution and bit depth
• Over larger coverage areas
• More frequently
• With more spectral bands
• IT Departments have not maintained the velocity of Geospatial Imagery in increasing
storage allocations
• Storage is still a constraint
• End users now demand like never before
• Fast end-to-end delivery of imagery. Time is critical
• Direct access to historical imagery
• Web service delivery
• Everything has to be fast.
