# Remote Sensing Information Gateway (RSIG)
If you are having trouble running RSIG, you may nee d to clear the Java applet cache. Check the RSIG version number in the lower right corner of the applet, under the contact information. If th e version number is 2014062718, then your applet version is up-to-date. If not, follow these instructions to clear the cache: Windows instructions. Mac instructions. Mac OSX 10.8 users should use Firefox to run the RS IG2D applet.

The Remote Sensing Information Gateway (RSIG) allow s for quick and easy access to subsets of multi-terabyte, environmental datasets via an interactive, Web brow ser-based application. A file download and parsing process that typically takes months is reduced to minutes w ith RSIG.

## About RSIG RSIG also allows users to integrate their selected datasets into a unified visualization. The user can tap into a wide range of key environmental models and data, such as NASA's Moderate Resolution Imaging Spectroradiometer (MODIS), the Environmental Protection Agency's (EPA) Community M ulti-scale Air Quality (CMAQ) model output, Nationa l Environmental Satellite, Data, and Information Serv ice (NESDIS) biomass burning data, and ground stati on measurements from AIRNow and EPA's Air Quality System (AQS). RSIG will render each dataset, and then overlay the m on a map of the selected region, automatically al igning information from various spatial and temporal scale s into a unified visualization. Currently, RSIG focuses on atmospheric data, but itcan be extended to support other types of geospati al data. A list of available datasets accessible via RSIG is a vailable on this site.
The benefit to users and consumers of environmental data is fast acquisition of only the data they wan t to see and in a standard format they can save to their des ktop PC. 

## RSIG Updated with New Features June 2012: Added NEUBrew (NOAA-EPA Brewer Spectroph otometer UV and Ozone Network) ozone profile data.

## RSIG's Availability One of RSIG's key innovations is its data delivery using conventional Internet and Web network connect ions. However, additional data traffic during peak networ k usage may degrade the overall system responsivene ss or a remote host's system may be unavailable or unrespon sive. The RSIG applet will display messages signali ng data unavailability in such cases. 

## RSIG's Key Features One access point to many data sources. The RSIG provides a single Web site that serves as a selective access point to many kinds of data. Streams only the needed data. The RSIG accesses large numbers of files from diverse sources and streams the user-selected subset of data back to the user's desktop. Streaming works in the same way as streaming audio works on the Web: the data goes directly to the client computer's memory and is discarded unless the user saves it to a file. Aggregates separate data files into a single stream. RSIG aggregates the multiple files of a given data type into a single stream, reducing the download burden and simplifying data analysis. Built-in visualization. RSIG can immediately integrate multiple selected datasets into a single MPEG animation. For example, EPA AIRNow data can be layered over NASA's MODIS satellite data, or a user can compare CMAQ predicted outputs and actual ground sensor data. The user can also save the anim ation or individual images to their computer. Saves data to standard formats. RSIG integrates incoming proprietary dataset format s into standard formats the user can save on their computer. A user can save the data or visualization--or both--to th eir

MPEG and KMZ. The user can then export the selected datasets from RSIG into other applications--such as GIS tools--for further analysis Fast. RSIG accomplishes all of this far faster than a lon e user could with currently available means. For example, RSIG can capture a week of MODIS AOD data in a few minutes, compared to two months using conventional web-form ordering/ftp approaches. 

## RSIG's Architecture This poster describes in detail RSIG's flexible and extensible architecture. The architecture enables RSIG to serve many types of data with an emphasis on convenience,high-performance, data integrity, and security. De pending on the speed of your connection, the poster may take a few seconds to load for viewing.

## RSIG Video Demonstration This 26-second screen capture shows RSIG retrieving various datasets describing the passage of Hurrica ne Katrina through the Gulf region. Five days of satel lite, wind, and cloud data clearly show Katrina's p ath as it makes landfall. Atmospheric researchers can use RSI G to easily view and retrieve all datasets related to a specific event, making it possible for them to anal yze the data much closer to real-time than has beenpossible before.
