Mapping Services

Description

WATERS exposes several mapping services that provide access to numerous datasets. This web page describes the content and purpose of each mapping service.             

Each service is provided in ESRI proprietary formats Exit EPA Disclaimer and Open Geospatial Consortium Exit EPA Disclaimer open standards formats to enable the display and query of spatial WATERS data. Non-developers can utilize these services using a variety of mapping and GIS applications. Using such tools, the WATERS mapping services can be used as a data source, transparently integrated with other data sources such as shapefiles or geodatabase layers. For developers, custom html-based web applications can be created that use standard web and mapping service syntax to make requests for data in order to display maps or tabular information.

ArcMap Based Map Document 

For convenience, WATERS provides a preconfigured ArcMAP based map document that contains pointers to the available ArcGIS based WATERS datasets. The MXD utilizes the Web Mercator MapServer services and requires the use of ESRI ArcMap 9.3.1 (or greater). WATERS also offers the WATERKMZ files that are KML (Google Earth) based documents.

 

Download
