[Geoserver-devel] [jira] (GEOS-4996) Support for KML altitude modes clampToSeaFloor and relativeToSeaFloor

Rafael Lucero created GEOS-4996:
-----------------------------------

             Summary: Support for KML altitude modes clampToSeaFloor and relativeToSeaFloor
                 Key: GEOS-4996
                 URL: https://jira.codehaus.org/browse/GEOS-4996
             Project: GeoServer
          Issue Type: New Feature
          Components: Google Earth KML Output
    Affects Versions: 2.1.3
            Reporter: Rafael Lucero
            Assignee: Andrea Aime
             Fix For: 2.1.4

Currently, the altitude mode of a KML extrude can be set through format_options and the altitudeMode parameter. The altitude modes that are supported include relativeToGround (default), clampToGround and absolute. The KML specification provides two additional altitude modes, clampToSeaFloor and relativeToSeaFloor that are unsupported by GeoServer.

The request is to have GeoServer recognize these parameters in the altitudeMode parameter. For example, if a height.ftl template exists and the URL is set to geoserver/wms/kml?layers=topp:states&format_options=altitudeMode:clampToSeaFloor, the resulting KML output should be:

<gx:altitudeMode>clampToSeaFloor</gx:altitudeMode>

This feature would be of great benefit to those of us who are outputting KML that is displayed underwater.
