Study Notes
Contour Lines and Elevations
- Contour interval is 50 feet, indicating the vertical distance between each contour line on the map.
- Elevation of Point A is between 755 and 780 feet.
- Elevation of Point B ranges from 670 to 680 feet.
- Elevation of Point C is between 570 and 580 feet.
Elevation Comparisons
- Point E has the highest elevation compared to other marked points.
- Point C has the lowest elevation among the lettered points.
Landscape Features
- The highest elevation feature is Rock Hill, with values ranging from 1105 to 1140 feet.
- The lowest point is where Rush Creek exits the map, between elevations of 410 and 445 feet.
- Local relief, or elevation difference between the highest and lowest locations, is approximately 700 feet.
Geographic Orientation
- Point F is on a spur or ridge on the hillside.
- Visibility: Point D cannot be seen from Point F, but it is visible from Point B.
Depression Characteristics
- Bottom of the depression southwest of Pine Hill has elevations ranging from 510 to 545 feet.
- The depth of the depression is 75 feet, measured from the lip at 600 feet to the assumed bottom at 525 feet.
Distances and Flow Direction
- Horizontal distance from Point C to B is 5800 feet.
- Rush Creek flows from north to south across the landscape.
Vertical Exaggeration Calculations
- Profile in Problem 1: Horizontal scale is 1 inch = 3000 feet, vertical scale is 1 inch = 300 feet, resulting in vertical exaggeration of 10 times.
- Profile in Problem 3: Horizontal scale remains 1 inch = 3000 feet, vertical scale is 1 inch = 150 feet, yielding a vertical exaggeration of 20 times.
Evaluation of Vertical Exaggeration
- Advantages include improved clarity in understanding the shape of hills.
- Disadvantages signify an unrealistic portrayal of relief due to scaling changes; apparent relief may seem exaggerated and misrepresent actual heights.
