it is GIS lab. if u are familiar with it, it will be really easy. Every chapter’s first 5 question
Exercises
Use the data in the BlaCkHIlls folder and SturgI883 geodatabasc to answer the lollowmg questions.
1. The Madison Limestone is an important aquifer. Citizens are concerned about gas or A
chemical trucks overturning on roads and causmg contamination. What is the total length 0!
roads crossing the Madison, in kilometers?
2. The infiltration rate of the geological substrate is a strong factor in evaluating the spill
I hazards for roads. Create a map of all the roads based on the infiltration capacity of the
geology, using appropriate symbols to indicate hazard. Capture your map.
3. The use of a road is another factor in evaluating spill hazard. Create a field containing a
hazard rating for each road based on both infiltration and use. For use, give primary roads a
value of 3, secondary roads 2, and primitive roads 1. What is the range of values for the
index? Create a map of the roads based on the hazard index. Capture the map.
Rangeland can cause significant impacts on surface water quality. Using the Iulc and
a 5 ‘ ‘wsheds2b feature classes, create a table showing the area of rangeland in each watershed.

places for fishing. Create a map showing these areas. Capture your map.
