Trends in Remote Sensing 1
• Historically, imagery was scarce and available to relatively few people
• Today, number of sensors, availability of imagery and variety of tools
are proliferating at unprecedented rate
• However, problems you are trying to solve are becoming more
complex, distributed
• Climate change
• Environmental management, monitoring
• Natural resources management
• Disaster response
• Etc…
• Change is a constant

GEOINT 3.0
Key Success Factor: Agility
• Goals of GEOINT 3.0: Enable better, more timely UNDERSTANDING
of challenges; DECISION-MAKING on courses of action;
MEASUREMENT of effects
• Requires AGILE collection, analysis, platform and delivery systems
to get the right information and insight rapidly to users when, where
and how they need it
• From Collect..................... to Connect
• From Orientation.............. to Understanding
• From GEOINT 1.0 (GIS).... to GEOINT 3.0 (Insight)

3D Model Creation

Improved Spatial Accuracy
with WorldView Satellites
• With Worldview, accuracy
within 4.1 meters, allowing
creation of ortho products/
maps with high positional
accuracy
•WorldView-1 & 2 CE90%
•Certified at 4.1m CE90%

Improved Positional Accuracy with
Multiple Collections Over the Same Area
GCP database
automatically generated
from WV class satellites
Multiple sensor bundle adjustment
uses multiple collections of the same
areas and overlapping strips will
reduce the positional errors from 4.1
meters to 1.5 meters, globally without
a need for GCP’s
Error: 4.1M
New error: 1.5M

Understanding – When, Where,
How You Want it
Problem: Put imagery in hands of people in field ASAP
Solution: DG Web Services:
Sample DG Web Services (via Google Earth)
• Map accurate base layer updated
quarterly
• Currency layer updated following
receipt of new imagery within:
• 18 hours (avg)
• 24 hours (worst)
• OPEN access - industry standard
interfaces:
• OGC standard WMS, WMTS,
WCS, WFS
