REACT – Rapid Environmental Assessment Composition Tools

REACT is a multi-OS network centric SW component that is part of the Decision Support Tools ACT is implementing under our Cooperative Agreement with NASA

(The overall scope of this CA is presented in the next slide)

Description and ObjectivesApplied Coherent Technology Corporation (ACT), the Naval Research Laboratory (NRLSSC) Oceanographic Division, and our NOAA partners, are under a cooperative agreement with NASA to maximize the value of NASA/EOS Earth science observations to decision makers related to coastal, marine, and ocean environments.

ACT and NRLSSC are integrating real-time ocean systematic measurements from NASA and NOAA satellites and available coastal observations along with coastal ocean model output into an automated real-time database of ocean weather in the Gulf of Mexico.

This project focuses on monitoring coastal ocean properties and it is aimed at providing new real-time support to NOAA efforts initially in the following focus areas: Harmful Algal Blooms (HABs), Coastal Flooding /freshwater discharge, and Hypoxia.

ACT in collaboration with NOAA will expand the project to other U.S. coastal areas and add additional NASA,NOAA,DOD and foreign data sources.

ApproachThe on-going effort is divided into an application component and a

and product research/development component.

• The Application Component [by ACT] – provides an architecture that addresses issues related to data ingestion, processing, distribution, access, and decision support. The key Decision Support Server and Fusion Server will be installed at NRL/SSC, followed by other servers at different NOAA sites.

• The Product Research/Development component [by NRLSSC] – provides state of the art oceanographic expertise and research addressing issues related to generation of new geophysical data products as part of a production pipe-line.

Schedule and Key DeliverablesYear 1: Application Component – a) Req. Gathering, b) Install high end HW/SW to

ingest/process/serve data, c) enhance current Fusion server & Decision Support Tool Technology.

Product R&D Component - ….

Year 2: Application Component – a) Demonstrate widely available internet access to all data levels, b) develop initial Hazardous Algal Bloom product based on satellite/model data in GIS and other compatible formats, c) add new data streams (e.g. NPP VIIRS)


Year 3-5: Application Component – a) Expand to other application areas, geographic areas, and data sources, b) identify and customize architecture to provide additional decision support tools, assist in transition of application to operation.

ACT is leveraging on an Network Centric Architecture that we have been using in a Number of NASA Planetary Missions, e.g.

•MSHELL - Image Processing Interpreter Language developed by ACT. The language has a high level syntax similar to Matlab and IDL.

•ProVIEW - Professional Windows Environment for Windows (ProVIEW). ProVIEW has extensive capabilities in image processing, analysis, and map generation.

•WIPE – WWW Information Processing Environment. Data Assimilation, Processing, and distribution system with batch and interactive capabilities.

MSHELL Provides the Computational Engine Used by ProVIEW & WIPE ProVIEW Provides Many of the Graphical Capabilities Used Under WIPEWIPE’s building blocks have been used in multiple mission critical operations

A new application called Rapid Environmental Assessment Composition Tools (REACT) has been implemented and continues under rapid development.

It captures elements of MSHELL+ProVIEW+WIPE all under an easy to deploy stand alone application, and portable GUI environment.

CORE SW Development

• As part of our NASA Cooperative Agreement, ACT has been participating in the Technology Infusion working group. The Technology Infusion has identified many capability blocks required in systems to support the EOS needs.

• REACT inherits key components of the ACT’s SW remote sensing SW tools– MSHELL - interpreter language with extensive capabilities for multidimensional data

manipulation– ProVIEW - graphical user interface around MSHELL– WIPE - provides fusion center architecture, with over 200 streams

• ACT has been using REACT and WIPE as a platform/architecture to demonstrate technology infusion from the OpenSource community, i.e.

– Qt – provides a portable library in C++ that allows GUI and system level support (A prototype version of REACT has been implemented for LINUX and Windows.)

– GDAL – the Geographic Data Abstraction Library is used by REACT to perform raster IO over many geo-graphic data formats new formats can be easily added following an OpenSource approach empowering developers to rapidly contribute in the adaptation of new formats. With Frank Warmerdam’s support extended this library with support for: CW-HDF, NRL-HDF, PCI-AUX (extended SRS support)

– gSOAP – used to SOAP enable REACT the developer needs to primarily concentrate on the core subroutine functionality. CONTINUED EXPANDING THE SOAP INTERFACE

– OpenGIS/OGC – describes protocols/methods used for the request of products (This is work in progress.)

– PROJ4 – a cartographic library with support to most of the projections used by USGS– SQLITE – a built-in SQL engine

• REACT is been configured to provide Web Services for geo-spatial data– Web Services Requirements are:

• Available over the Internet• Not tied to any operating system or programming language• Self-describing via a common XML grammar• Discoverable via a simple find mechanism

• REACT captures a WIPE like type of interface for accessing inventory queries and generating mosaics, a set of five core functions are being added to the REACT/MSHELL scripting language resulting in a LARGE space of remote computing capabilities/options! (implemented using SOAP)

– $result = rmshell_execute($server, $scriptCommandList )– Data = rmshell_getVar( $server, $variableName)– $result = rmshell_putVar( $server, $variableName)– $result = rmshell_getFile( $server, $inFile, $outFile )– $result = rmshell_putFile( $server, $inFile, $outFile)ADDITIONAL FUNCTIONS WERE ADDED TO HANDLE ASYNCHRONOUS REQUESTS

• The above functionality can be exported to other applications via WSDL (an XML grammar for specifying public interface to the web service)

• The Challenge…Decision Support Tools means different things to different users, e.g.

– Data Provider or Server need coverage and cartographic maps/mosaics with simple to use query engines

– Analyst at Fusion Center • Visualization Tools, e.g animations of layers, volumetric vis.• Implementation of a Process in the form of a Wizard• Analysis: Multivariate Detection/Estimation/Prediction/…

– Coastal Manager GO/NoGo results with access to supporting data

• ACT has been working during the last year in the above end-user categories with requirements driven by NRL, NOAA/NOS, NOAA/CW, NOAA/CSC

Summary• REACT has been under active development. The HAB analysis tools within REACT

are being tested right now. • We have just started the technology infusion of REACT to our NOAA potential

users…• The feedback of the Technology Infusion Group in terms of how to exercise this

process is very valuable to us.
