The link two sections above accesses the NASA GLOBE Visualization server (see ), which provides comprehensive information on the world's environment and is updated daily. The maximum temperature is one of the many maps available from institutions that receive raw data and process it into geographic information displays. These two request types are the only ones you need to achieve all the functionality described in this tutorial. You'll find that you use the first two almost exclusively. The WMS specification defines three request types: GetCapabilities, GetMap, and GetFeatureInfo. There's a link to a WMS FAQ on that page, too.Ī WMS request is an HTTP-GET message sent to a WMS server. It contains information essential to using WMS, and it's free! A WMS discussion list exists at /mailman/listinfo/wms-dev. Give it a look when you're done reading this article. As standards go, the WMS standard is not hard to read, and it's blessedly short.
The next version, 1.3, (version number 1.2 was skipped) is in development as of April 2004.

The full WMS specification is available at The most commonly implemented version is version 1.1.1, but there are still some servers stuck at version 1.0. Data providers and application developers are increasingly adopting WMS. WMS is a web protocol created by the OpenGIS Consortium as a standard way to request and deliver geographic maps and associated information over the web.

This article gives an overview of WMS, and it presents C# code to retrieve maps and perform other operations necessary when working with WMS servers and information. There are additional parameters possible, but the ones above are the required ones.

Each element of the URI is a defined parameter of the WMS protocol: The base path of the URI identifies the WMS server the query sting specifies the desired maps and how to represent them.
The URI you just followed is an example of a Web Mapping Service (WMS) GetMap request. The map you saw in your browser should have looked something like this, which shows the world's maximum temperatures on April 23, 2004: Come back here afterwards to learn how it works.Įditor Note - Spaces inserted into URL to avoid horizontal scrolling For example, follow the link below to retrieve a world map of today's highest temperatures. IntroductionĪn amazing number of free, interesting, and just plain beautiful geographic maps are available on the web, and they can be easily retrieved programmatically using the Web Mapping Service protocol developed by the OpenGIS consortium ( ). Several utility classes for accessing WMS servers and information are provided and described. The tutorial provides C# examples of progressively increasing complexity to illustrate use of the protocol and programmatic access from Windows.
This tutorial introduces the Web Mapping Service (WMS) protocol standardized by the OpenGIS Consortium for retrieving geographic maps over the internet.
