Question

activity 9.2 map location, distances, directions and symbols

ap Locations, Distances, Directions, and Symbols Activity 9.2 Name: Date: Course/Section: What are the latitude-longitude coordinates of point B in Fig 9.2 Latitude Longitude Refer to Fig. 9.8, which describes the Public Land Survey System (PLSS) 1. Review Fig. 9.8 to understand how the location of point X in Fig. 9.8C was determined using PLSS shorthand. What is the location of point Z in Fig. 9.8C in PLSS shorthand? 2. How many acres are present in the township in Fig. 9.882 (Hint: There are 640 acres in I mi.) Show your work. S. Imagine that you wanted to purchase the NE 1/4 of the SE 1/4 of vection 11 in Fig. 9.8C. If the property costs $500 per acre, then how much must you pay for the entire property USGS 30 ×朴minute quadrangle maps have a scale of 1:100,000. 1. One inch on such maps equals about how many miles? Show your work 2. One cm on such maps equals about how many meters? Show your work. The standard base map for many regional geologic studies is the 7.5-minute topographic quadrangle. Imagine that a field uncertainty areca associated with that GPS unitif you ploted it as a circle on the 124000 scale map (ia mm)? t uses a handheld 12channel GPS receiver with a location uncertainty of 15 m. What would be the diamder of the E Refer to Fig. 9.5. 1. What is the bearing (azimuth) from point c to point d? 2. What is the bearing (azimuth) from point d to point e? F Refer to the Ritter Ridge. California, 7.3-minute topographic quadrangle map in Figs. 9.3A and 9.38. I. What are the latitude-longitude coordinates of the NW corner of the map?

Answer 1

Ans A: Latitude 40⁰  South and Longitude 20⁰ West

Ans B: (1) Point Z is located in the center of the southwest quarter of the northeast quarter of the southeast quarter of section 11.

This can be written in shorthand as : SW1/4, NE1/4, SE1/4, SECTION 11 T1S R2Wal geologic studies

Ans B: (2) Acc. to the question:

1 sqmile = 640 acres

So in Fig 9.8(b) 6x6 mile area is shown.

So 6x6 sqmile = 36 sqmile

and 36 sqmile = 36x640 acres

which comes out to be 23040 acres.

Ans B: (3) Acc. to the question:

NE 1/4 part is of 0.25x0.25 = 0.0625 acre

SE 1/4 part is of 0.25x0.25 = 0.0625 acre

So total areas of property to be purchased= 0.0625 + 0.0625=0.125 acre

Now the cost of 1 acre property is $500

So cost of 0.125 acre property = 0.125 x 500= $62.5

Ans E: Fig 9.5 is missing.

Ans F: Fig 9.3 A and Fig 9.3 B missing.
