Web Map Service

A Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the Internet that are generated by a map server using data from a GIS database.

You can choose your server by the dropdown list or by typing it in the box. Then you have to inspect it and select the available maps.

At least there is a summary of map, after checked it you can press "Finish" button and complete procedure.

The WorldMap must be an image file stored in an image file (JPG, PNG, etc. type). It needs to be provided in Equirectangular projection. You have to choose your image map from the file chooser button and optionally a Legend image to display a map key on the map. In this example we have downloaded the following file: image

FAQ

What is a Web Map Service?

A Web Map Service (WMS) produces maps of georeferenced data. We define a "map" as a visual representation of geodata; a map is not the data itself. WMS is the production of spatially referenced data dynamically from geographic information. The map itself is an actual portrayal of geographic information presented as a digital image file for display on a computer. WMS maps are in picture formats such as PNG, GIF or JPEG . The OGC WMS specification standardizes the way in which maps are requested by clients and the way that servers describe their data holdings.

What is an Equirectangolar Projection?

This is a type of projection for mapping a portion of the surface of a sphere to a flat image. It is also called the "non-projection", or plate carre, since the horizontal coordinate is simply longitude, and the vertical coordinate is simply latitude, with no transformation or scaling applied. The equirectangular projection was used in map creation since it was invented around 100 A.D. by Marinus of Tyre.
