Stereo Imagery products are designed for users with advanced
image processing capabilities and photogrammetric tools. This
product is ideal for Digital Elevation Model (DEM) generation, 3D
visualization, and feature extraction applications. Stereo images are
collected in-track, meaning on the same orbit, and are acquired at
angles optimal for stereo viewing and manipulation.

The Jargon and what does it mean?
•
VNIR – Visible and Near Infra-Red
- The satellites have camera filters that see beyond what human eyes can see
- There is valuable information within our visual range and beyond
- Example: Vegetation and health can distinguished clearly in Near Infra-Red as
opposed to human visual range
•
SWIR – Short Wave Infra-Red
- This the range after Visible and Near-Infra-red (longer wavelengths)
- More information is available for identifying different materials and features
21
The Jargon and what does it mean?
•
CAVIS – Our internal acronym (and we love our acronyms!)
- Sensor designed to measure atmosphere and normalize imagery to improve
image quality
- Also allows to create accurate metadata on clouds, snow and ice
- CAVIS designed to improve imagery yield especially in cloudy areas
-
C – Map Clouds
A – Measure Aerosols or Particles in atmosphere that affect image quality
V – Measure Water Vapor that affects image quality
I – Map Ice and differentiate it from clouds and snow
S – Map snow and differentiate it from clouds and ice
22
What is the unique value of WV3 VNIR bands?
•
•
•
VNIR bands will be collected at 1.2 meters
Continuity of bands from Worldview2
Useful for Forestry and Agriculture Applications
- Red Edge Band ideal for analyzing vegetation health
•
Useful for Marine Applications
- Yellow band best suited for mapping Submerged Aquatic Vegetation
- Coastal band (in addition with Blue, Green, Yellow bands) well suited for
Bathymetry

Recent Developments and Enabled Opportunities
33
Not since our ancestors domesticated the dinosaur has
there been such innovation in Precision Ag !
34
Remote sensing can detect effects before, during and after
growing season essential to productivity and efficiency
Examples:
• Directed scouting to collect non-RS ground truth and samples
• Soil surveys using site specific zones instead of uniform grids
• Moisture deficiencies/excesses detected earlier (sub-visual)
• Nutrient deficiencies detected earlier (sub-visual)
• Insect infestations detected and treated while localized
• Weeds detected and treated while localized
• Diseases detected and treated while localized
• Growth regulation to maximize fruit yield
• Harvest scheduling based on optimal natural dry down
• Yield prediction to inform in-season decisions and trading
• Potential for on-the-go combine adjustment for yield variance
35
VHR space and ground systems can address key enabling
remote sensing requirements for production agriculture
•
Necessary revisit frequency and time of day
- A few times during the soil preparation/planting periods
- At least weekly during growing season up to harvest (2x-3x per week better)
- AM orbit is essential to avoid large shadow shifts and afternoon stress shifts
•
Necessary Ground Sampling Distance (GSD)
- 25cm to 50cm GSD pan sharpened RGB is optimal for “scouting from desk”
- 1.0 to 2.0 meters GSD for Multi-Spectral (MS) bands is optimal for info
•
Necessary spectral properties
- 16 MS bands in VNIR/SWIR offer the best Ag and national security utility

species and conditions of selected species
