WMS in Metamod

OpenLayers - JavaScript client for web. Uses extended WMC support library developed by

NcWMS - integrated with THREDDS. Cannot render shapes, only grids.

MapServer - used on for displaying coastlines

Perl proxy/web service. Merges GetCapabilities and WMSsetup file using XSLT. Also works as proxy to get around security limitations in JavaScript.

The OpenGISĀ® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application.

WMS example

XML document describing all available layers and styles in a single data file. Lacks projection and bounding box info.
