Hello, On February 22, I sent a message that had a few questions in it, but I've gotten no response. Here are the questions (plus 1 or 2 new ones): Regarding transfer of data from RCs to NSIDC: 1. Would anyone object to scrapping the Parameter Value Language file and instead using shapefiles to transfer attribute data (see Feb 22 mail)? 2. If you think doing the above is a good idea (or a bad one), please let me know your vote. 3. Hugh, Rick, Jeff: What is the status of the software you're developing to aid in image analysis (and does it have a name?)? 4. Luke: Since it was your suggestion to use shapefiles for all attributes, do you have ideas about how to improve the scheme I outlined in my Feb 22 message? Maybe you could add detail? The PVL/shapefile decision will affect everyone doing analysis, so we need input soon.
