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
and
Open Geospatial Consortium
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 (MXD) 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 9.2 (or greater). WATERS also offers the WATERKMZ files that are KML (Google Earth) based documents.| Download |

ArcGIS Usage Notes
- WATERS data is served in both the NAD83 (_NAD83) and Web Mercator projections (_WMERC). Services are postfixed with either _WMERC or _NAD83 to indicate their purpose.
- Caching - WATERS services utilize caching to optimize server performance. Caching is a process whereby cartographies are prerendered at specific scales and stored as small images or tiles. These small images may be provided to web clients much faster than rendering the cartography on demand. Both on demand and pre-caching strategies are used for Web Mercator based services. WATERS will continue to enhance and build out the cache in strategic areas.
-
Symbology - WATERS is continually reevaluating WATERS dataset styles.
The cartography of the services is still a work in progress.
Efforts are underway to resemble the cartography of both the
USGS NHD SLD
and ESRI's upcoming NHDPlus base map.
-
Keyhole Markup Language - Some _WMERC services contain Layers with a (KML) postfix.
These layers are specifically configured to serve KML clients by working around symbology limitations inherent in the format.
See the KML specification
for more information on the types of symbology available using KML services.
