The interactive mapping applications available on our web site provide a relatively easy way for you to directly view our GIS data without being a GIS expert. These applications draw data from our GIS databases and present it to you in a web browser interface. In addition to not only being able to visualize the data through a map, many of the applications allow you to query and download the data to your local machine.
Due to the graphical complexity of some of the GIS data, some maps may take a long time to load, especially over a slow connection. You are also required to have Javascripting enabled and popup blocking disabled on your web browser interface.
Published GIS Services
In addition to the interactive mapping applications, our web site hosts Open Geospatial Consortium (OGC) interfaces such as web mapping services (WMS) as well as an ArcGIS Server REST API. The OGC WMS protocol defines a simple interface for web-based mapping applications. The WMS protocol is based on a simple query syntax for posting a request for the desired layers and region to the server, which returns a map as a standard image (GIF, PNG, JPG). The capabilities of a WMS are described in an extensible markup language (XML) document. Here is an example of how to use the information provided by this document to generate a map of oil and gas pipelines, artificial reefs, and coral habitats along the Louisiana-Mississippi coastline using our WMS connector.
The ArcGIS REST API provides a simple, open Web interface to services hosted by ArcGIS Server. All resources and operations are exposed by the REST API are accessible through a hierarchy of endpoints or Uniform Resource Locators (URLs) for each GIS service published with ArcGIS Server.
For example, to get to the root directory of our ArcGIS Server services, the URL is:
http://www.ncddc.noaa.gov/arcgis/rest/services
From this base URL, you can traverse to any of the listed services and resources and operations associated with the service.
