- This FAQ is the work of several authors, without whose valuable
- contributions, suggestions and encouragement it would not have been
- possible.

- 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- have an out-of-date version (e.g. printout, CDROM), you can get a more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.

- _Note: the satfaq address is an autoresponder. If you are offering new
- material or commenting on the existing contents, you should start your
- subject line with keyword "submit" or "comment" respectively, which
- will be filed for my attention when I do the monthly updates. All
- other mails will generate automatic replies._
- _________________________________________________________________
-
- 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!!!)
