At the heart of this revolutionwill be Internet Search Portals suchas Microsoft Virtual Earth, whichwill change the way we search andexplore our world, drastically reducingthe time necessary to gatherlocation-based information. Thetime-savings gained will make individuals,businesses and governmentagencies—particularly local lawenforcement, emergency preparednessand homeland security—moreefficient and effective. And, muchas the first wave of the commercialInternet created a business ‘ecosystem,’this new Virtual Earth-basedwave will as well.Vexcel’s technologies will becritical to this geospatial revolution,serving as Microsoft’s center of excellence,providing the best-of-breedimagery that will make up the VirtualEarth ‘real world’ framework. Indoing so, the company will continueto work towards enabling the visionthat many in the geospatial industryshare—the widespread availabilityand use of digital Earth informationto enhance society.w w w . i m a g i n g n o t e s . c o ms u m m e r 2 0 0 625
