Getting <strong>Map</strong>s<br />

The primary reason to use or establish a <strong>Web</strong> <strong>Map</strong> <strong>Server</strong> is to obtain or serve maps. Use the Get<strong>Map</strong><br />

request to obtain images from a WMS server. Get<strong>Map</strong> requests are always sent as HTTP strings and<br />

the response is a map image with well-defined geospatial and dimensional parameters in the image<br />

format specified in the request.<br />

Inputs and Behaviors<br />

When invoking Get<strong>Map</strong> a WMS query can specify:<br />

Input<br />

VERSION=version<br />

SERVICE=WMS<br />

REQUEST=Get<strong>Map</strong><br />

LAYERS=layer_list<br />

STYLES=style_list<br />

SRS=namespace:identifier<br />

<strong><strong>Map</strong>Info</strong> <strong>Spatial</strong> <strong>Server</strong> <strong>Web</strong> <strong>Map</strong> <strong>Service</strong><br />

Description<br />

Request version. <strong><strong>Map</strong>Info</strong> <strong>Spatial</strong> <strong>Server</strong> WMS supports both<br />

version 1.1.1 and 1.3.0 of the OGC specification.<br />

<strong>Service</strong> type. This is always WMS.<br />

Request name. For a Get<strong>Map</strong> request this is always Get<strong>Map</strong>.<br />

The layer or layers to be included in the map image. Each<br />

layer should be separated by a comma. For example:<br />

LAYERS=Layer1,Layer2,Layer3<br />

Comma-separated list of one rendering style per requested<br />

layer. A style is required for each layer requested. If no style<br />

is requested, the attribute must be present but without a value.<br />

If requesting multiple layers, the styles listed should be in the<br />

same order as the layers. For example:<br />

STYLES=Style1,,Style3<br />

Chapter 3: <strong>Web</strong> <strong>Map</strong> <strong>Service</strong> Capabilities<br />

In the above example the second style (for the second layer<br />

requested) is left blank, allowing the default style defined for<br />

the layer to be used.<br />

The spatial reference system used in the map (numeric representation<br />

of the projection of the map, also known as the<br />

coordinate reference system). This parameter is only used<br />

for 1.1.1 versions of the OGC specification. If this is not specified,<br />

the default spatial reference system, as defined in the<br />

default style of the layer, is used.<br />

The coordinate reference system used in the map (numeric<br />

representation of the projection of the map, also known as<br />

the spatial reference system). This parameter is only used<br />

for 1.1.1 versions of the OGC specification. If this is not specified,<br />

the default coordinate reference system, as defined in<br />

the default style of the layer, is used.<br />
