JMap map imaging service
This type of service is mainly used by developers who wish to obtain map images produced by JMap.
Application options |
|
Image format |
Select the image format that will be created by JMap Server and displayed in the application. JPEG generally offers the best quality/size ratio when the map contains air photos. |
Image params |
This option allows you to specify additional parameters to be used when creating images. Currently, this option is only used with the JPEG format to specify the quality setting, which controls the quality/size ratio of the image. The default value (when the field is left blank) is 0.5. Entering a lower value will result in images of lower quality but will allow smaller sizes. Example: quality=0.6 |
Controlled access |
This option determines if access to this application must be controlled. If this option is activated, an authentication window will be displayed at application startup. Note that this option must be consistent with the permissions defined at project configuration. If anonymous access is not authorized for this project, a connection window should always be displayed. Otherwise, access will systematically be denied |
WMS Service
Web Map Service (WMS) is a standard presented by the Open Geospatial Consortium that determines how client applications must perform requests in order to obtain maps from a server that is compatible with WMS.
JMap Server can act as a WMS server. If you implement a WMS web service, other applications can query JMap Server via the WMS protocol for the selected project. Once the service has been deployed, you can click on Launch to display a page containing 2 hyperlinks: the first one is the getCapabilities request you must provide to the systems that wish to query JMap's WMS service. The second one is an example of a getMap request that allows you to obtain a map image.
WFS Service
Web Feature Service (WFS) is a standard presented by the Open Geospatial Consortium that indicates how client applications must perform requests in order to obtain vector data and its attributes from a server that is compatible with WFS.
JMap Server can act as a WFS server. If you implement a WFS web service, other applications can query JMap Server via the WFS protocol for the selected project. Once the service has been deployed, you can click on Launch to display a page containing a hyperlink towards the getCapabilities request you must provide to the systems that wish to query JMap's WFS service.
