System Introduction
- Provisioning Data over San Diego |
| |
 |
Runtime:
90 seconds. This first demonstration provides an overview
of how a user provisions data with EarthWhere using
the interactive map interface. The custom data product
created in this demo is a mosaic formatted with the
user specified projection and datum from several sources
of imagery (satellite, aerial and scanned maps) that
were each stored in their various datum, projection
and file formats.

Data Element
Access Control |
| |
 |
Runtime:
120 seconds. This demonstration shows how EarthWhere's
security system restricts access to licensed or confidential
datasets. The built in gazetteer is used to navigate
and define an AOI. The custom data product provisioned
with this demo is a "3D topographical map"
by blending a scanned map (USGS DRG) with 5 meter
shaded relief licensed from Intermap.

DOQ Histogram
Matching |
| |
 |
Runtime:
60 seconds: This demonstration shows how EarthWhere
improves the consistency of processed data. The single
point (GPS) search function is used to define an Area
of Interest (AOI). This AOI requires 4 color USGS
DOQ's with inconsistent tonal and radiometric qualities
to be combined to make a new product. The different
combining options as well as the histogram matching
functionality is used to provision a new data product
with constant tonal quality.

Provisioning
Raster Data for Supporting Wildfire Management |
| |
 |
Runtime:
90 seconds. EarthWhere can be integrated to work with
a wide variety of third party applications. This demonstration
shows how ESRI ArcIMS can be used to capture the necessary
information and passed to EarthWhere for provisioning.
This demonstration shows the ArcIMS application being
used by the US Department of Interior in the 2003
firefighting season to automatically provision standard
raster data products to expedite wildfire containment
in the western United States.

Provisioning Raster Data directly for Desktop Applications |
| |
 |
Runtime: 120 seconds. EarthWhere can be accessed by desktop applications via the EarthWhere API. This demonstration shows how ESRI ArcMap (part of ArcGIS) can be used to capture the necessary information and passed to EarthWhere for provisioning. This demonstration shows the power of the EarthWhere API by provision raster data products on the fly and directly placing them in the end users application.

you just defined. EarthWhere™ updates the map with
footprints showing where data exists, and the data is color-coded
on the map to match the source of the data listed in the
Available Data Elements table. The numbers
in the middle of the footprints correspond to the ID for
that particular record in the Available Data Elements
table.
