DESCRIPTION:
In this event, students will use remote sensing imageiv to analyse the impact of human and natural
activities such as agriculture, forestry, urbanization, mining, manufacturing, volcanic eruptions, etc.,
on the physical environment Students will also evaluate the relationship of a local area or regional
physical environment to its cultural landscape. To accomplish these tasks students may use any
combination of the following remote sensing imagery or products of remote sensing images.
Aerial photographs
Topographic maps
satellite imagery
planimetric maps
radar imagery
public records A TEAM OF: 2 APPROXIMATE TIME: 50 MINUTES
Students will be supplied with all maps, images and photographs necessary to complete the activity.
Students may bring protractors, calculators, rulers, notes, reference materials and other devices.
Students are not to mark on the maps, photographs, or images.

SAMPLE TASKS:
Lightning strikes have caused an extensive forest fire. Using aerial photographs of the burned area
ITrnM prep an overlay for a ^P^P"10 "^P ^ the region. Estimate the total number of acres
A local city council is planning to construct a new river dam to divert irrigation water to developing
agricultural lands. The site has been selected for the dam, which will have a spillway elevation of
348 feet. 1) Determine the area in square miles, which would be inundated using that level 2) How
many existing homes will be affected? 3) How many acres of forest must be cut?
SCORING:
The number of correct responses recorded determines places in the competition. Pre-identified
questions will-be used as tiebreakers. Time is not a factor.
