Folks: I have a very general comment on CF Swath related to geolocating pixels in a swath.
Level 1/2 product generation systems that output remotely sensed swath data from polar orbiting systems often have a concern/requirements related to keeping the volume of data to a minimum. If I am reading the CF swath proposal correctly, it would seem there is an assumption that lat/lon coordinates for each pixel is required to be CF compliant. This adds significantly to the size of a NetCDF-CF product file containing swath data. Has there been any thought to define some type of a polar orbiting satellite projection that includes requisite time, orbital, and sensing map parameters in addition to explicit lat/lon values in the product file ? Note that this question is not just limited to swath data coming from polar orbiting satellites. v/r randy > On Apr 30, 2018, at 1:56 PM, Charlie Zender <[email protected]> wrote: > > Dear CFers, > > We wish to draw your attention to and invite feedback on two proposals > to extend CF: > > CF Swath, for encoding remotely-sensed (a.k.a. swath) data > https://github.com/Unidata/EC-netCDF-CF/blob/master/swath/swath.adoc > > CF2-Group, for files with netCDF4 Groups > https://github.com/diwg/cf2 > > Questions/comments may be made as GitHub issues at their respective > repositories.
