![[SIR-CED LOGO]](../CEDLOGO.GIF)
This CD was designed for use by students at middle schools, high schools and colleges. It contains radar images of sites all around the world as seen before and during the SIR-C missions. It also contains hand held photographs from the Space Shuttle, QuickTime movies from the missions, photographs from the ground, etc. Lesson plans are provided to help you learn about the images.
You can use this CD in many ways from just viewing pictures
to performing science experiments with real data
taken from Earth's orbit. You can learn about Earth Observation and
Imaging Radar through structured lesson plans, think up your own
experiments, and analyze radar image data from the SIR-C
missions. This gives you
the ability to do
the same kind of scientific analysis as scientists
who are using SIR-C data
in their studies. It's easiest to start by using the
Netscape browser provided with this CD.
Navigating Around The CD
You can view all the images, movies, documentation,
lesson plans and learn all about imaging radar in the
Guided Tour
using the
Netscape browser interface. This is like having part of the
Internet's World Wide Web (the Web)
on a disk! If your computer has Internet access, there are links
provided to a
companion Home Page to this CD, and to other NASA
educational resources, such
as Spacelink.
For some activities, such as image processing, you will have to go outside of the Guided Tour and traverse through the CD's directories and files. The CD Reference Section is your guide to the CD's directories and files.
System Requirements
This version of the CD was especially prepared
for the IBM-PC and compatible
machines.
However this CD is ISO-9660 compatible so
the image and text files should be readable on Macintosh and
Unix machines too.
The minimal computer hardware and operating system
you will need to run the software on this CD:
It is recommended that you have at least 10 megabytes of free hard disk space available on your machine. You will also need a sound card with speakers if you wish to hear the sound from the Quicktime movies. You can still play the movies without sound though.
Use the Lesson Guide sheets as handouts for your students, or as overhead slides to prompt classroom discussion. The Lesson Guides work best when combined with the slides materials (in the Slides directory), so that students learn a little (from the teacher presenting the slides), then think a little (by going over the Lesson Guide materials). Use the Teachers' Guide as a reference book so you can answer student questions or to supplement the presentation materials.
Select the materials that you think will work best for your class. This will depend on their grade level, ability and what kind of computer equipment is available in your classroom. In the one-computer classroom, try to do the computer exercises as a joint class effort, with students guiding your hand (or mouse). If you have a computer lab, have the students copy the data and/or software they will use for a given lesson onto their own disk. This makes finding files a lot easier.
The directory /DATA/MODS1TO5 contains all the images used in the
lesson plans, divided up into 5 modules.
Each module contains the images as described in the
corresponding lesson module.
Opening Files On The CD
You can see most of the images on this CD and learn about
imaging radar by using
the
Guided Tour.
You can also directly access the images,
text files, radar data and software from the
topmost directories on the CD labeled
/DATA,
/DOCUMENT and /SOFTWARE.
For a map of the directories and files, see the
CD Reference section
There are six basic types of files on the CD. The following is a description of the files:
| File Extension | Description |
|---|---|
| *.htm | HTML (Hyper Text Markup Language) files. These files can be read with a Web browser like Netscape which is included in the CD-ROM. |
| *.gif | GIF image files. These image files can be viewed with a Web browser like Netscape. |
| *.pic | PICT image files (Macintosh). On the PC, these files can be viewed with the Picture Viewer program which comes with the Quicktime movie package. On the Macintosh, these files can be viewed with the NIH Image or SimpleText programs. |
| *.stk | Compressed Stokes image files. Can be viewed with the Sigma0 program included on this CD. |
| *.txt | Plain ASCII text files. These files contain raw text. These files can be read with a Web browser like Netscape which is included in the CD-ROM. |
| *.mov | Quicktime movie files. Can be viewed with the Quicktime Movie Player included in this CD. |
