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. <Learn More>
 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. <Learn More>
 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
).

This interactive quick-map product was
created using ACT-REACT and now access from a
simple web-browser. 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 image shows lunar targets
overlaid on a composite Lunar basemap. ACT
has implemented a web interface that allows the
general public to select and submit targets of
interest for possible observation by NASA's Lunar
Reconnaissance Orbiter Camera
(LROC ). This work was done
in support of the LRO/LROC
operations team at Arizona State University
(ASU). The interface leverages direclty
in ACT PIPE™ and ACT-REACT™.

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. |
