E.g., station data (wx balloons) Who are the potential main service providers/users of this tool? Server – Should we? • When we put scientific data in a mosaic, we can expose this through an image service, WMS, WCS, WFS – is there a need to support OPeNDAP in the server piece? • If so, who has this requirement?
