The Remote Sensing Information Gateway (RSIG) is a tool for selecting, downloading, assembling, and visualizing atmospheric data. After the data has been assembled, it can be stored on the user’s workstation, if desired. RSIG is developed by the US Environmental Protection Agency (EPA).

The RSIG application is operated by selecting from among fifteen or so variables available from the following data sources:

  • NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) data
  • AIRNow and Air Quality System (AQS) ozone and particulate-matter observations
  • EPA's Community Multiscale Air Quality (CMAQ) model output
  • National Environmental Satellite, Data, and Information Service (NESDIS) biomass burning data

More details on RSIG's data sources can be found at http://rtpmeta.epa.gov/portal/datainventory.html.

The application then assembles the data from local files or by submitting requests over the Internet to data repositories at NASA, Sonoma Tech, etc. RSIG then presents a visualization of the data on a latitude-longitude map, automatically locating the data in correct geographic position.

RSIG uses program code that runs on NASA and NOAA servers to select and subset large datasets at the source computer center. Transmission over the Internet to the EPA is thereby accelerated compared to conventional techniques.

RSIG can save the collected data in the following formats:

  • Binary External Data Representation (XDR) format
  • NetCDF format
  • ASCII spreadsheet
  • MPEG or PNG format files for visualized images


Access and Status

The RSIG application is operable but is still in the final stages of development. The application can be accessed two ways:

  • All workstation users connected to the EPA network can access http://rtpmeta.epa.gov/portal/rsig2D.html.
  • Users outside the EPA can request access to the EPA Portal at portal.epa.gov. RSIG can be accessed from the Environmental Science Connector on the Portal.

Java Requirements

RSIG is a Web browser-based application that runs as a Java applet. Therefore, RSIG carries the following Java requirements:

  • Java Runtime Environment (JRE) 1.4 or better
  • a .java.policy file saved to your Home directory. The .java.policy file is a simple text file that ensures you can save data from the RSIG applet to your computer.

The RSIG web sites listed above contain full information on installing the .java.policy file for Linux, UNIX, Mac OS, and Windows systems.

Access to RSIG Data

In addition to the Web browser-based Java applet, RSIG offers additional ways for researchers or applications to access data.

Streaming access. Applications with specific information needs can use RSIG's CGI scripts to enable streaming access to RSIG's data. This can effectively automate access to any data that RSIG can access and deliver the data to your application in the desired format. These scripts are in the review process, but are accessible from within the EPA intranet.

Web server scripts. Assuming your application is running on an EPA computer inside the EPA firewall, then the application should access http://maple.rtpnc.epa.gov, which is the internal computer containing the web server scripts. (Tthe MODIS script is on a public NASA computer.) The scripts will eventually be hosted on external EPA computers for external/non-EPA clients. The server scripts are OGC-WCS-compliant. For more information, see http://rtpmeta.epa.gov/portal/webscripts.html.

Sponsorship and Contacts

The RSIG application has been sponsored and managed by ORD’s National Exposure Research Lab (NERL). The Principal Investigator is Jim Szykman. The application is being developed by the EPA Environmental Modeling and Visualization Laboratory (EMVL).
