Introduction

   This FAQ deals with imagery of Earth from Space. It aims to combine
   some very brief introductory material with a guide to the numerous
   resources available on (and off) the Internet. It is the work of
   members of the IMAGRS-L (Image Processing & Remote Sensing) LISTSERV.
   We hope it will be of value to those whose work, studies or casual
   interest involve Remote Sensing of the Earth.
   
   I have also included a couple of Remote Sensing answers. The
   philosophy here is simple: if it's somewhat relevant, and someone's
   posted (and I've seen) a good piece, then it may get included.
   
   This is an Internet document, and is generally updated monthly. If you
   have an out-of-date version (e.g. printout, CDROM), you can get a more
   up-to-date version from the addresses below.
   
   _Call for Contributions:_ There are gaps in this FAQ. In addition,
   much of the material comprises my very brief and sketchy entries to
   cover what would otherwise be gaping holes! If you can fill any (or
   all :-) of them, please help!
   
   Material I can just cut-and-paste in is most likely to be useful/used.

   This FAQ has five parts, loosely classified as:
    1. Contents & other meta-information (this document).
    2. General Questions
    3. Technical Questions
    4. List of RS satellites & instruments, with pointers to information
       on the Net. Note that this does not appear in the Table of
       Contents, but is used as html links from elsewhere in the FAQ.
    5. Further Reading (long!)
       
   For newsgroup comp.infosystems.gis, they are merged into a single
   file, to ensure the GIS-L gateway rejects it and doesn't flood readers
   mailboxes (someone please tell me if this fails!!!)
