National Levee Database
The spatial data stored in the National Levee Database are available for public use. The core mapping data can be used in Geographic Information System (GIS) desktop and web applications via the Web-GIS Service URLs below. Use these services to add NLD data to your maps, change layer styles, and export selected features. The JSON API allows users to access geospatial and tabular data.
| Resource Hyperlink | Resource Format | Description |
|---|---|---|
| Feature Service | REST ArcGIS Feature Service | NLD Core Mapping layers exposed by an ESRI Feature Service |
| Map Service | REST ArcGIS Map Service | NLD Core Mapping layers exposed by an ESRI Map Service |
| OGC Service | OGC OWS | The NLD's WMS and WFS services use the "ows_" metadata reference in lieu of "wms_" and "wfs_", which allows a single endpoint to support both mapping and feature services. The URL provided below can be used for adding both WMS and WFS services to your GIS client. |
| JSON API | REST/JSON | RESTful web service, using standard technologies like HTTP verbs, headers, and status codes. |
