Company Background: Space-Time Toolkit and Hurricane Opal
The Space-Time Toolkit was a product co-developed by the company's founder,
Ron Phillips, while working as a Senior Research Associate at the Global
Hydrology and Climate Center. The first use of the Space-Time Toolkit involved visually fusing data from multiple
satellites and ground-based products in a tool that, in real-time, geolocated and remapped
the data from the North American landfall of hurricane Opal. The combined data could
then be interactively animated and manipulated in 3D to see the visual correlations in the
radar and satellite data for this destructive storm system. The tool used the following
data sets in their "original" format, that is, with no preprocessing to put the
data into a common spatial or temporal grid:
- GOES satellite data in a Mercator map projection with 15 minute temporal resolution
- OTD (Optical Transient Detector, i.e., a lightning detector) satellite's visible-light
images in CCD (charge-coupled device) "sensor-space" with 1 minute temporal
resolution
- OTD satellite's lightning detection events in CCD sensor-space with roughly 10 msec
temporal resolution
- CONUS (continental US) radar precipitation in an equirectangular map projection with 15
minute temporal resolution
- CONUS ground strike lightning events with 1 second temporal resolution.
This Space-Time Toolkit technology demonstration was heavily used by the OTD Lightning
Team to illustrate the numerous meteorological,
military, commercial, and life-saving advantages inherent in an orbital
lightning-detection system.

North-American landfall of hurricane Opal. Shown is the visual fusion of data from
the GOES satellite (shades of blue-to-white), the OTD satellite visible-light data
(grayscale), the OTD satellite lightning data (red dots), and the CONUS precipitation
product (shades of green-to-red), all geolocated and remapped in real-time. Each
dataset has its own independent time synchronization and time display capability, allowing
the OTD products, for example, to be visually combined over a longer time range than the
other datasets, highlighting the OTD's lightning detection capabilities. |
