Schedule for a 6 Hour Workshop

This is a general outline for a 6 hour workshop. You may choose items to build your own workshop following the guidelines below. In order to complete these exercises with minimal difficulty in terms of time management, you should have access to a Power Macintosh with 32 MB of RAM or a 486 PC running at 166 Mhz, with 32 MB RAM. For reference, the CASDE Education Home Page is <ois.unomaha.edu/casde>.

If you would like to participate in a CASDE Workshop, please send for a supporting CD. Following this guideline as you work with the data installed on the disc, you will be able to successfully complete tutorials, tour sample lessons and be able to observe and manipulate digital data. We would encourage you to construct your own building blocks for use in your classroom and/or share it on the CASDE Internet Server. Contact Paul Clark.

8:30 - CASDE "First" CD-ROM Review

  1. Overview: Background information and the history of the CASDE program.
  2. Perspective: An Educator's Perspective. The CASDE Program as viewed by an experienced teacher who has received a multitude of service and teaching awards.
  3. Greetings from the Senator: An Introduction by Senator Kerrey. The Senator is one of the driving forces behind a successful, innovative educational program.
  4. Load Software: (PC) Load 'Aladdin Expander' which expands on any platform, 'msjav' which allows machines to use the JAVA script and 'Snagit' which does a screen capture and saves the selection in a graphic file.
  5. Macintosh - Go to the Apple Menu and select 'Jigsaw Puzzle'. Load selected images and comment on the file format for each. Compare the pieces to image elements called pixels. Make screen captures with "Command-Shift-4' keystroke. Take some digital pictures, save and load them into :Puzzle".

9:00 - Some Space Data Activities

  1. The Nebraska Map Puzzle - Each team selects a map piece and analyzes it - Are there any distinguishing features? Lakes? Rivers? Cities? Agricultural areas? Which way is North? What are some distinguishing characteristics which will enable you to detect these features? Use a marker to place information on the puzzle piece. Can you identify the area? Does more information help define the map area? Combine the teams and place the puzzle pieces together.
  2. Examine a local poster if possible. Make identifications. An Assignment: Upon making the identifications, make of list of questions and answers designed to help with map interpretation of your poster. A dozen or so will make a good "pink sheet".
  3. 9:40 - Virtual Nebraska: Explore the history of Nebraska towns, examine their infra-red images and digital elevation models with maps of the corresponding area. Check weather maps and experience remote sensing tutorials. Posters are available of many locations in Nebraska.
  4. 10:15 - DataSlate - Load the "Current" CASDE CD-ROM. Go to 'DataSlate Documentation' for the history and development of DataSlate. Load images from the Selection Grid. Use the 'Zoom' feature, see the 'x-y' coordinate window, switch between data and text for a particular site. Each Data Set may contain different types of images.... radar, natural, infra-red, thermal....... These images may be from aerial or satellite photography.
  5. 10:20 - The Atlantis of Nebraska - Republican City, Nebraska was originally located in the flood plain of the Republican River. When Harlan County dam was built, the original site was flooded and the city was moved to a higher elevation. Can you find the original and the new locations? What evidence supports your conclusions?
  6. Where on Mars is Snoopy? - Select the proper image to find the rock named Snoopy. (10:35) Give the "x" and "y" coordinates. Use red-green glasses to examine the 'threed' image.
  7. Time Traveler - Observe some changes that have taken place in Grand Island, Nebraska as well as decide why some of these changes have taken place. Examine the rail yards in particular.
  8. Load images from someplace other than the Selection Library. (Clouds, Millard area....) Suggestions for other images?
  9. Weather Across Nebraska - Determine how rapidly a cloud front moves over a portion of the state of Nebraska. Can you predict the time of arrival of the front in other portions of the state?

11:00 - DataSlate Tutorial - Tools Version - Tools (ruler and area, angle, GPS, pushpin, magnifier) Notice that angle 0° is 'up' or 'north'. Use the "Magnifier" to show how a digital image is made of individual blocks called pixels. Select different tools, change units and 'reset' for another measurement.

11:15 - Tool Application - Make trial measurements within your data sets.

The 'Zoom' control selects a different image set with higher resolution. This will account for the 'magnification'.

Examples: Millard area and it's growth.

Comment on how the participants could select and use their own images for use in DataSlate.... "The Virtual Frog". Mention that the images are loaded into DataSlate by using images with a 'SimpleStruct' file format.

Examine a DataSlate Tutorial
Examine the CASDE Education Website. Lunch: 11:45

1:00 - Capture images. Go to 'Washington DC' on the Terraserver and capture the image around the 'Mall' area using 'SnagIt'. Be sure to capture the 'scale' in your selection. (check the map)

1:15 - File Formats - Refer to 'file formats', conversions and image capture devices. Convert a JPEG image to SimpleStruct format.

1:20 - Terraserver - Explore Terraserver, locate your own area and..... Notice that there is an option for viewing the political map beneath the images.

1:50 - NIH or Scion Image - Take the image saved previously from "Terraserver" and load it into NIH Image. Be aware of the file formats required for this. Find the scale on the image and make some measurements. Try 'stretching' the image. Sharpen, smooth..... Refer to Scion Image Tutorial.

2:15 - WebShop Tour followed by Question and Answer Session

Well, all well and good but .....what can I do with this information?

WEB site Support, Updates (CD-ROMs hold lots of information and are convenient but they are static. CASDE will be adding datasets and resources, improving software, and collecting user experiences. Additions, corrections, feed-back and further explanations, when available, will be posted on the World Wide Web),
