New Software Bundles for Workshops in 2008
Mac OSX versions:
Color Basics Software 2008
Digital Image Basics Software 2008
Analyzing Digital Images Software 2008
PC Windows versions:
Color Basics Software 2008
Digital Image Basics Software 2008

Measuring Vegetation Health Software and Guides
Programs are listed in the following sequence of concepts: color, basics of digital images, and visualization and analysis tools. Utility programs are also available and are listed at the bottom of the list.
For each concept grouping, software is bundled for one-stop downloading. Or consider downloading all of the programs at once.
Download the proper version software for your computer: OSX (Mac), Mac "Classic" (OS9 and earlier), and Windows (PC). Several programs are being rewritten to Java for interactive web activities (no downloading needed) by Tom Whittaker at the University of Wisconsin-Madison's Space Science and Engineering Center. These applet links are marked by "Java."
Software Requirements
Programs that manipulate images require Quicktime 5 or later to be installed.
If not installed, download for free: Mac PC/Windows.
All software programs are "zipped". You will need the proper freeware utilities installed on your computer.
Many programs, except the color programs, require a screen resolution of at least 1024 x 768.

| TriColor |
Explore the colors created by mixing varying intensities of red, green, and blue light.
Current Version: 4 –– Mini Tutorial |
OSX OS9 PC
Java |
| GameTriColor |
Test your ability to identify the intensities of the red, green, and blue components of a color on the computer screen. Play another person or against the computer.
Current Version: 6 –– Mini Tutorial |
OSX OS9 PC |
| ReportTriColor |
Measure how well you can identify the intensities or red, green, and blue for 10 random colors. A report is generated on-screen and in a text file.
Current Version: 7 –– Mini Tutorial |
OSX OS9 PC |
| Bundled Basics of Digital Image Programs |
PixelView (both versions) , ColorPicture, LeafAnalysis, SplitColors, FalseColor, SurfaceType, and SurfaceTypeRGB that are described below. |
OSX OS9 PC |
| PixelView |
Study the effects of changing the size of pixels for any digital picture (jpeg, gif, tiff, png, pict, pdf)–called pixelation.
Current Version: 4 –– Mini Tutorial and See Examples of the Impact of Pixels |
OSX OS9 PC |
PixelView
for
Demonstrations
and
Science Centers |
Same basic functions as PixelView but 10 "mystery" pictures are available in the window by clicking on their 2x2 pixel icon. Download includes pictures and text file (see details below). Requires 1024 x 768 screen setting.
Notes: Menu bars toggles on/off with control-M.
Place your own pictures into the folder with the software and when the program opens, these pictures are used. Size of pictures must by 512 x 512.
Names of pictures must be "mystery#.jpg". Put names of pictures (or clues up to 32 characters) in "mysterynames.txt" with the first line of text corresponding to mystery1.jpg.

OSX
OS9
PC |
|
Separate the red, green, and blue color components of any digital picture (jpeg, gif, tiff, png, pict, pdf).
Current Version: 6 –– Mini Tutorial |
OSX OS9 PC |
|
Designed for use in science centers, load two images (jpeg, gif, tiff, png, pict, pdf) and explore the red, green, and blue intensities at any pixel in either image. When used with pictures of plants, goal is for users to discover plants absorb most red and blue light and reflect more green light.
Current Version: 6 –– Very basic version of ColorPicture (use this Mini Tutorial for basics) designed for young children and/or science centers. Compare the colors in two pictures displayed in one window by clicking anywhere within the pictures. |
OSX OS9 PC |
|
More advanced manipulation of the red, green, and blue color components of any digital picture (jpeg, gif, tiff, png, pict, pdf).
Current Version: 4 –– Mini Tutorial |
OSX OS9 PC |
| FalseColor |
Similar to ColorPicture, manipulate the color display components of a Landsat image from USGS Earthshots.
