Tour: An
Exercise in Vector Addition
DataSlate and Interpretative
Questions
Possible Questions and Answers Relating to This Image
( Image Analysis
Tutorials are available from the UNL site.)
- Do you find evidence of any agricultural regions in this part
of California? What is the evidence? In which
locations? You
may decide to check the following Informational Modules at UNL:
A
Guide to the Practical Use of CIR in Agriculture
and Agri-Sensing;
"Precision Ag".
- Record the x - y coordinates and the
latitude - longitude values for the middle of a center
pivot.
- Compare different regions of the image in terms of topography
and give evidence to support your conclusions.
- Locate Highway 101. Describe its path.
- Lake Cachuma is located just east of Solvang. Give the 'x-y'
coordinates of the lake, record the latitude and the longitude of
the lake, find the perimeter and the area of the surface. Measure
the length of the dam on the west end of the lake. How do you set
the scale for this measurement?
- Refugio Road may be a possibility for a trek over the Santa
Ines Mountains toward Solvang. (The name of the town is Danish for
"Summer Field".) Examine the area for possibilities for a mountain
pass. Try CIR, radar, dems.......
- Ocean Meadows and Sandpiper are golf courses just off Hwy 101
not far from Glen Annie Road. Can you find them? Locate the Santa
Barbara Municipal Airport (east of the golf courses) and record
the 'x-y' coordinates. What is a good image to use for this
exercise? Be sure to record the name of the image and the "Zoom"
level.
- Record the vector from Santa Buenaventura to Santa Barbara.
(as the crow flies) Record the vector from Santa Barbara to Santa
Ines. Notice that the results will be different if you measure
from city to city or from mission to mission. Does it depend on
the detail of the map?
- Use the AREA tool to find the distance from Santa Barbara to
Santa Ines: a) across the Santa Ynes Mountains, along the shore of
Lake Cachuma and on to Santa Ines; this route is generally current
Highway 154, b) along the beach to the end of the Santa Ynez
Mountain chain and back up the valley along the Santa Ynez River
to Santa Ines, and c) along the beach to Refugio Road and across
the mountains to Santa Ines. Such mountain roads sometimes follow
old game trails because wild animals will pick the easiest path to
travel.
- Examine the image for temperature contrast. Why are there such
wide temperature ranges?
- Where is the highest elevation point? What is the best image
for deciding on the highest point? Give the x-y values for this
point.
- Which way does the Santa Ines River flow? Give clues for this
reasoning.
- Record the GPS for the Santa Ynez Mission.
- Compare distance and "degree of difficulty" for the suggested
path for the Indian boy. You may make allowances for vegetation,
topography...... Contrast views using: radar, CIR, thermal,
natural.....
- Finally, What is your recommendation? Which path should the
Indian boy take? Your reasons?
