Basic Information
The TRI.NET application is focused on capabilities a user needs to analyze TRI data effectively, such as a robust ad hoc query capability and the ability to integrate with mapping. In addition, the application uses the latest mapping technologies of Virtual Earth, Google Earth, and Google Maps for Mashups.
TRI.NET is consistent with EPAs interest in "Web 2.0" applications as it leverages current technologies to create a more agile environment that takes advantage of the capabilities of modern computing platforms on the user side and Internet capabilities to serve up data and provide geospatial services.
Architecture
The data engine is developed in the Microsoft .NET framework for querying large enterprise databases. The software uses the Firebird embedded Relational Database Engine, a high-performance open source data engine. The application is also tightly integrated with the latest mapping technologies in the Web 2.0 space.
Data Application
EPA TRI data and other data layers have been ported over to the application. The TRI data has been enhanced with several value-added data layers including Environmental Justice, Tribal Lands, and U.S Mexico Border. In addition to pounds-based TRI data, TRI.Net also includes Toxicity x Pounds based Hazard information to assess toxicity.
Automatic Updates
To ensure users will have easy access to the latest versions of TRI data and software, this application uses auto-updating by deploying software and data updates automatically. Data and software updates are handled by an auto-update feature that connects with a Web server to download the latest data and software. The software automatically checks for updates when it starts and notifies the user if new data or software is available.
Maps
Virtual Earth, Google Earth, and Google Maps technologies are leveraged to provide Mashups that connect EPA data to maps. The application renders maps in both Google Maps and Google Earth dynamic mapping environments. Once an ad hoc query of TRI facilities is completed the facilities can then be mapped and EPA reports can be run. The application is synchronized with the latest FRS locational reference data for mapping.
My TRI Neighborhood
The software also allows users to get a micro picture of TRI releases by showing TRI releases in small communities and mapping those TRI facilities releasing chemicals in their neighborhood. The software has the ability to geocode addresses so that the user can base queries on the ad hoc neighborhood.
