Chapter 7 - Cartometry
Azimuths range from:( 7.4-5 ) 0 to 2 PI 0 to 90 0 to 100 0 to 360 0 to 6400
0 to 360
A map is: - A scaled model of all or part of the earth's surface - Features are converted to symbols - Involves simplification - Is very critical for spatial reasoning - All of the above
All of the above
Distances on the ground can be measured with: - Pacing - A tape - A surveyors wheel - A chain - All of the above
All of the above
To follow a bearing to a target in the field: - Use a compass or map to select a target on the right bearing - Calculate how many paces to take - Carefully count down the paces - Walk around obstacles, using side-steps out and then back when you are around the obstacle - All of the above
All of the above
We need to account for magnetic declination because: - It changes over time - It changes depending on where you are - It can vary both east or west of True North - It can be accounted for on a compass - All of the above
All of the above
What should be true of a map legend? - All the symbols used in the map should also be on the legend - The symbols set should contain none that are unused on the map or map series - There should be an explanation of how the map deals with missing or unavailable data - The text should be clear and worded unambiguously - All of the above
All of the above
To measure map distances directly off the map, use: - A map wheel - The paper strip trick - Calculate from coordinates - Use the TerraGo toolbar - Any of these
Any of these
The bearing 325 degrees uses which measure of direction? - Azimuths - Clock face - Compass points - Common bearings - Mils
Azimuths
Making measurements from maps is called: - Mapology - Cartography - Cartosophy - Cartology - Cartometry
Cartometry
The bearing N25W uses which measure of direction? - Azimuths - Clock face - Compass points - Common bearings - Mils
Common bearings
Which is the third and last cartographic transformation? - The scale transformation - The projection transformation - The choice of coordinate system - Convert features to symbols - Printing the map on paper
Convert features to symbols
An example of a mixed feature shown on USGS topographic maps is: - School - National Park Boundary - Railroad yard - Coral Reef - USPLSS Section Numbers
Coral Reef
To convert radians to degrees: - Multiply by 180/PI - Add 90, 180 or 270 depending on the quadrant - Multiply by 0.3048 - Pick any number between 0 and 10 - Convert both to mils first
Multiply by 180/PI
An example of a line feature shown on USGS topographic maps is: - School - National Park Boundary - Railroad yard - Coral Reef - USPLSS Section Numbers
National Park Boundary
Coordinates can be used to compute the distance between two points by using: - estimation - Eratosthenes' theorem - Pythagoras' theorem - the strip of paper trick - stadia
Pythagoras' theorem
An example of an area feature shown on USGS topographic maps is: - School - National Park Boundary - Railroad yard - Coral Reef - USPLSS Section Numbers
Railroad yard
An example of a point feature shown on USGS topographic maps is: - School - National Park Boundary - Railroad yard - Coral Reef - USPLSS Section Numbers
School
A method used in surveying that reads values from a pole where two horizontal cross hairs fall on the scale is called: - Meters and bounds - Leaps and bounds - Gunter's Chaining - Stadia - Electronic distance measurement
Stadia
To calculate the length of a line with 10 straight segments given by 11 coordinates: - Plot the line on a map, and use the paper strip trick - Take the average of the x and y values - Calculate the length of the line from the first point to the last - Use Pythagoras' theorem on each segment individually, then add the lengths together - Use Pythagoras' theorem on each segment individually, then multiply the lengths together
Use Pythagoras' theorem on each segment individually, then add the lengths together
With which of these can you determine south, given a sunny day? - Observing Polaris - Using an analog watch - A strip of paper - A slice of pizza - Noticing which side the bark grows on trees
Using an analog watch
