It enables Agency access to its geospatial data in ARC/INFO format, integrates these data in a standardized, framework. Environfacts was developed as an enterprise data repository for Agency data systems. It is a relational database implemented in the Oracle Relational Database Management System and contains seven EPA's program system databases. Geospatial Data Clearinghouse provides a pathway to find information about geospatial data used at EPA. Although ESDLS can be accessed through several GIS applications, it is mainly for EPA internal uses. Meanwhile, Environfacts can be accessed by the public through Internet. Spatial Data Clearinghouse currently provides public access to its metadata. However, it is promised that public can access its geospatial data via the Internet in the future.
