negative outcomes enabled with current data -ASTER: Low resolution
pixels. Archive only - SWIR failed in 2008. -Airborne: Weather
delays, remote sites, complex permitting. Limitations and
Consequences of Current Methods over come by WV3 Misinformed
decisions with economic consequences Delayed Exploration Delayed
Exploration Costly Programs Missed Opportunity

DigitalGlobe Proprietary and Business Confidential WV-3 Science
and Theory Radiance and Reflectance - Data normalization Material
Identification - Spectroscopy
Slide 12
DigitalGlobe Proprietary and Business Confidential Whats
Radiance? radiance vs reflectance Radiance is what a satellite
measures. It is how much energy; light or heat as reflected by
something -Things look different when they are brightly or dimly
lit. -This is radiance. 12
Slide 13
DigitalGlobe Proprietary and Business Confidential Why
Reflectance? radiance vs reflectance Reflectance is a constant,
predictable property of the material. -Reflectance is a ratio.
OUT/IN = reflectance -This is reflectance. In Out Percent of light
that is reflected! 50% 13

Slide 16
Hydrocarbon (HC) Spectral/Geochem Model A - Trapped HC in
subsurface (can be either structural or stratigraphic trap) B - HCs
migrate upward along micro fractures, fracture systems, and fault
zones. The presence of HC molecules tend to generate a reducing
environment, thereby liberating metal ions. This is particularly
applicable in clastic rocks containing detrital Fe and Mg C - Metal
ions near the surface are washed away by groundwater. The resulting
outcrops and residual soils appear anomalously altered or bleached

Definitions Digital Terrain Model (DTM) = Earth surface without
vertical objects. Digital Surface Model (DSM) = Earth surface with
vertical objects (e.g. trees, buildings). Digital Height Model
