Roy, >From this page: http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.3/reference/collections/FeatureCollections.html It looks like the only "featureType" values currently allowed in a FeatureCollection are TDS 4.2: FMRC, Point, and Station TDS 4.3: FMRC, Point, Station and GRIB We've been doing FeatureCollection FMRC featureTypes with netcdf files and it works fine. But I don't think you can use FeatureCollection for joinNew or joinExisting aggregations of netcdf files yet. -Rich On Sun, Feb 17, 2013 at 10:26 AM, Roy Mendelssohn - NOAA Federal <roy.mendelssohn@xxxxxxxx> wrote: > Hi Rich: > On Feb 17, 2013, at 4:10 AM, "Signell, Richard" <rsignell@xxxxxxxx> wrote: > >> "If you have joinExisting Aggregations, coordinate information will be >> written to a cache directory....Every scour amount of time, any item >> that hasnt been changed since maxAge time will be deleted.
