Cartographers and earth scientists solve problems differently, even though their domains and representations
have similarities. In both cases, there are spatial domains, visual representation, huge data and continual visual
and computational analysis.
The cartographer's canvas is the earth's surface, naturally diverse in form, differentiated by man's uses, dominion
and constructions. The diversity of resulting mixture of entities is daunting. However, while maps result from
dynamic processes, they are not usually dynamic: although that is changing.
Earth science plays in a four dimensional arena containing spatially and temporally continuous phenomena.
Historically, ways and means to acquire, analyze, transform, model, and visualize four dimensional data have
been limited. New polar orbiting smart sounders like AIRS and AMSU-A acquire high resolution, 3-dimensional
retrievals of water vapor, temperature and trace gases. This puts pressure on the rest of the process to deliver the
data in useable form.
Satellites orbit relentlessly creating new instrument footprints and geophysical parameters, as the earth rotates.
This creates a geometrical shape called "The Swath". The shape is geometrically straightforward. Just imagine
wrapping a bowling ball with duct tape. However, it is new to cartographers because it is temporal:
Nonetheless, a swath can be projected, and footprints and parameters can be transformed into cells, points,
bins, objects, volume features and curtains (read layers). These entities are familiar to cartographers. However,
fully incorporating time is a big challenge.
That's where we are now. In a combined JPL/Redlands Institute/ESRI effort we use
simulated visualization to probe ahead, but at the same time, prototype tools to enable basic interoperation
between EOS data and ArcGIS: selecting AIRS/AMSU-A L2 granules and transforming them into point features
and raster layers. We will move to modeling and visualization tools. (The presentation will contain some of our
visualizations and descriptions.)
