If you want the sharpest satellite imagery in the world, then you should harness the power of DigitalGlobe satellite imagery.
To give you a ballpark figure: Each pixel in a Worldview-3 image is about the size of home plate on a baseball diamond. That’s about 31 cm. So instead of being far-sighted, you can see a better and clearer world with some of DigitalGlobe’s products.
There is a real need to create new, insightful information products that can be used to proactively investigate flood-prone areas across a whole range of scales – from sites to river basins to a national level. Elevation is the single most important variable in determining flood hazard levels, and we focus on this by developing three flood analysis tools. Each can be implemented at scale and is a significant undertaking. We hope these tools can provide more geographic context and shed light on some key hydrodynamic processes about flooding.
The multi-billion dollar a year activities linking aerial imagery with geospatial technologies expands more rapidly than you can blink an eye. Government and commercial contracts dominate the growth, especially for military, security, agriculture, and forestry applications.
