Point Clouds: Service Functionality in WCS WCS Core: access to n-D coverages & subsets format encoding on the fly subset = trim | slice WCS Extensions: optional functionality facets Future: Clustering, thinning, etc on Point Clouds? WCS Application Profiles: domain-oriented bundling of extensions EO, MetOcean, (Sensors), ... PointClouds? Large, growing implementation basis: rasdaman, GDAL, QGIS, OpenLayers, OPeNDAP, MapServer, GeoServer, NASA WorldWind, EOx-Server; Pyxis, ERDAS, ArcGIS, ...

Extensible Support by Coverages Point Cloud data: uniform embedding in one of OGC’s base structures high-level uniform handling of space + time format independent Point Cloud services: function-rich, mature service framework Harmonized with relevant other OGC standards
