ACT-REACT Workstation
 This screen capture shows
ACT-REACT in action during an Earth/environmental
decision support session. The user is able to accesses
data from multiple disparate sources and ACT-REACT
fuses the data into a multi-layered map projection --
enabling visual analytics and direct interrogation of
the underlying data values. During this session,
ACT-REACT accessed satellite-based sensor data along
with model, in-situ and higher level data products from
multiple sources such as: local hard disk, FTP,
OGC/WCS&WMS, OPenDAP, and WIPE servers.

 This image
(click image) shows a QuickMap mosaic created by a
work-flow in ACT-REACT, which the user can modify in a
simple manner. The work-flow used accesses data
from multiple servers at NOAA+NAVY/NRL+ACT, and creates
value added layers, including map-reprojection.
The mosaic contains derived chlorophyll
temporal mean and anomaly layers, overlayed on
MODIS cloud free data. It also shows water sample
results around the coast of Florida. This is
part of a joint ACT, NAVY (NRL), NASA and NOAA
environmental analysis initiative, where ACT
provides the geospatial data management and analytic
architecture to support this environmental assessment
project. <Details>
 ACT-REACT is being leveraged in
several NASA planetary missions. Scientists and mission
teams use the system for: (1) collaborative
planning/targeting -- to view and interrogate historical
lunar/planetary data to identify, geolocate, describe,
and share potential sensor targets; (2) work with new
sensor data products -- visualize new data and mosaics,
interrogate data values (e.g. mineralogy maps, spectra
ratios, altimetry, etc.); and (3) monitor mission
progress -- view mission progress through sensor
coverage maps and visualize coverage vs. targets, etc.

 This image replays an ACT-REACT user
zooming in on MARS at high latitude to a location with a
MRO hyper-spectral CRISM observation. In the process
ACT-REACT fuses multiple data sets to guide the users’
navigation and interpretation process.
The CRISM
team is using ACT’s PIPE and ACT-REACT software to
compile a global map of Mars at approximately 200 meters
(660 feet) per pixel. The map is acquired as thousands
of individual strips, each about 10 kilometers (6 miles)
wide. Over the Mars Reconnaissance Orbiter's two-year
primary science phase, these mapping strips will cover
nearly the entire planet, in a manner similar to
covering a beach ball with many thousands of pieces of
string <Image> (note: large, animated gif
image). ACT-REACT is also used by MRO-CRISM
to create web accessible maps of MARS and CRISM spectra
via ACT-REACT-QuickMap ( see_overview
).

Interactive access to MERCURY's
maps from NASA's MESSENGER
Mission
ACT has customized
ACT-REACT-QuickMap to monitor mission progress
of NASA's MESSENGER Satellite in
Mercury. This version of
REACT-QuickMap provides rapid access to
footprints of instrument observations,
access to global
mosaics, search of observations within
an area of interest, and simple download interface
to NASA's Planetary Data System.

Interactive access to
Lunar maps from NASA's LRO/LROC
Mission
In support to NASA's
Lunar Reconnaissance Orbiter
Camera (LROC) operations
team, at Arizona State University
(ASU), ACT has customized ACT-REACT-QuickMap
to let the public :
-
Perform Target
Observations Requests , i.e the public
requesting the satellite high resolution camera
to capture images over specific locations on the
Moon surface.
-
Navigate multiple Lunar global
and regional map products using LROC
REACT-QuickMap. The
interface allows to navigate over
multiple map projections and up to very
high resolutions, i.e. 0.5
meters/pixel.
REACT-QuickMap
leverages direclty in ACT's PIPE and
ACT-REACT. |

This interactive quick-map product was
created using ACT-REACT and allows simple
web-browser access to map data. It
depicts the use of surface currents
model products from NRL/SSC and
Chlorophyll Anomaly products from
NOAA/NESDIS. Also shown is the value
added product of
predicted surface
drifts over a period of 72
hours. The start time is
12/09/2009. This is part of a
case study where an analyst create this
product to assist a search/rescue operations
team. (click image to

This animated gif is automatically
generated by an ACT WIPE server every 30 minutes.
The server accesses recent data from NOAA/GOES
satellite and fuses it with terrain elevation and
bathymetry data (ocean depth) and automatically
generates a new animated .gif file. WIPE server
can access, fuse and create new products on a
scheduled basis, or access data, apply algorithms
and serve data/images "on the fly" for an area and
temporal period
requested. |
