Re: Point data netCDF example & description

I have updated our service

CF-1.5,  CF:featureType = "point"
http://webapps.datafed.net/ogc_EPA.wsfl?SERVICE=WCS&REQUEST=GetCoverage&VERSION=1.0.0&CRS=EPSG:4326&COVERAGE=AIRNOW.pmfine&TIME=2008-12-19T15:00:00&BBOX=-130,24,-65,52,0,0&WIDTH=-1&HEIGHT=-1&DEPTH=-1&FORMAT=NetCDF-table

CF-1.5,  CF:featureType = "stationTimeSeries", 5.8.2.1 Multidimensional 
representation
http://webapps.datafed.net/ogc_EPA.wsfl?SERVICE=WCS&REQUEST=GetCoverage&VERSION=1.0.0&CRS=EPSG:4326&COVERAGE=AIRNOW.pmfine&TIME=2008-12-19T15:00:00&BBOX=-130,24,-65,52,0,0&WIDTH=-1&HEIGHT=-1&DEPTH=-1&FORMAT=NetCDF-sts

In the website, "point" was spelled with lowercase, so I used it.

The format names in query, NetCDF-table and NetCDF-sts I have just made 
up, WCS spec should standardize them.
