We have purchased a large >amount of GOES-8 data at NCDC that dessiminated these data under the >McIdas format. I am trying to read these files. I use a routine found on >the web written in IDL.

I am not familar with the use of IDL for GOES imagery data in McIDAS AREA format. >More generally, I have read the block of navigation data in the AREA file >but I can not figure out how to deduce the pixels postions from the values >find in this data block like reference latitude, reference longitude, >reference yaw..... I did a quick Google (tm) search using 'IDL +GOES' as a search key and found the following site at the Cooperative Institute for Research in the Atmosphere (CIRA) at Colorado State University: Usage of IDL http://www.cira.colostate.edu/special/csuidl/tips.htm Reading McIDAS AREA files - Tips... http://www.cira.colostate.edu/special/csuidl/IDLMcIDAS.htm The Site Index for the above: http://www.cira.colostate.edu/special/csuidl/index.htm lists several IDL applications developed at CSU/CIRA for displaying GOES GVAR imagery stored in McIDAS AREA format. In particular, one called 'GVAR View' (or GVIEW) appears like it would be useful to you: http://www.cira.colostate.edu/special/gview/gview.htm >Have you an idea of where to find the necessary informations to retrieve >the navigation data of GOES-8. I think that the CSU/CIRA site should get you going. >Thanks a lot for your help. No worries. >Gilles > >Gilles Molinie >NIS-1 Group Office (Space and Atmospheric Sciences) >TA-3/1888/01U >Bikini Atoll Rd., SM-30 >Los Alamos National Laboratory >P. O.
