GIS Lives in this World Imagery Lives in this World
Integrating Mapping and Imagery
Applications for Improved Decision
Making
Today’s global trends are driving the need for more information and data regarding our surrounding world.
> Climate Change
> Population Growth
> Disaster Management
> Scarce Resources
The Growing Need for Geospatial Information
The growing need for geospatial information is driving the demand for software technologies that can:
> Deliver useful information to decision makers quickly
> Be tailored for different applications
> Extract meaningful information from imagery rather than just offering a visualization
Geospatial Information Technologies
> Easily share information across a
network of users
> Key component to modern workflows that are aimed not only at the visualization task, but also the information extraction task….
Multisource Fusion for Multidimensional Analysis
Future Visualization Technologies
> More applications demand the use of
multiple data modalities
> Combining and exploiting multisource
data sets simultaneously will be the new
norm
> Integration of Radar, LiDAR, Optical,
Hyperspectral, Stereo, Thermal and more
is driving how applications consume and
process data
> These modalities will be combined to
create an even richer geospatial context
for decision making
Imagery Is At the Heart of Geospatial Analysis
Imagery is essential for
enabling people to
understand the world.
Imagery is not just a
base map, but a layer
of rich information.
What Problems Are Faced By Users Needing Imagery?
Hard to reach areas
Out of date information
Need for
automated/rapid
processing
Increasing amounts &
size of data
Great reduction
in manual digitization
How Does Imagery Solve Those Problems?
Project Results
> Up to date information
> Automated and faster processing
> Obtain actionable intelligence to make informed
decisions
> More efficient workflow to achieve results
Analysis Results
> Land Cover Analysis
> Change Detection
> Material Identification
> Object Based Analysis/Feature Extraction
> Detect Anomalies
> And many more
