Question
What are the latitude-longitude coordinates of point B in Refer to FIGURE 9.8 (PLSS). Review FIGURE 9.8 (o understand Sow the location of point x in FIGURE 9AC was determined using PLSS shorthand. What it the location of point z in FIGURE 9.8C In PLSS shorthand? How many acres are present in the township in FIGURE 9.8B? Imagine that you wanted to purchase the NB 1/4 of the SE 1/4 of lection 11 in FIGURE 9.8C If the property corn $500 per acre, then how much mini you pay for the entire property? USGS 30 times 60 minute quadrangle maps haw a scale of 1: 100.000. One inch on such maps equals about how many miles? Show your work. One cm on such maps equals about how many meters? Show your work. Most handheld 12-channel parallel GPS receivers haw an error of about 5 m when they fix on their position, and most geologists plot their data on 71/2-minute topographic quadrangle maps that haw a ratio scale of 1:24.000. If an object is 5 meters long in real life, then exactly how long (in millimeters) would it be on the 1:24.000 scale map? Refer to FIGURE 9.4. What is the bearing from point C to point D? What is the beating from point C? . Refer to the Ritter Ridge. California. 71/2-Minute topographic quadrangle map in FIGURE 9.3. What are the latitude-longitude coordinates of the NW corner of the map? What is the UTM zone and designator letter for the location of this map? In what year was this map originally made? In what year was it photorevised? What is the magnetic declination for this region according to the map? What is the PLSS location of section 21 in the southwest corner of the map?Explanation / Answer
Answer:A
The latitude is the horizontal axis line on the map and longitude is the vertical axis line, where these both the lines intersect one can find out the values of their longitude and latitude.
Answer: B
There are shorthand term which are used to locate point as follows :
Ranges: These are the area between two meridian lines.
Survey township: It is the area of land about 6 square miles, which contains sections.
Sections: Each section contains 640acres.
Answer: C
The given format of scale is RF(representative fration) 1:100000
1:100000 means 1 inche(map) = 100000 inches (ground)
1mile= 63,360 inches
Therefore, 1 inch= 1.57 mile
Now, 1:100000 means 1 cm (map)= 100000 cm (ground)
1 meter= 100cm
1cm= 1000 meters.
Answer: D
1: 24000 means 1 mm(map)= 24000mm(ground)
1 meter= 1000mm (for 5m = 5000mm)
The object of 5 meter would be of 5000mm on the map, therefore this object would be very small on the map.
