Question

true or false

1. maps generally use an oblique view to show as much of the earths surface as possible.
2. a map scale of 1:50,000 is larger than a scale of 1:300,000.
3. north, south, east, and west are always the same, no matter where you are on earth.
4. great circles on a globe do not have to pass through the north and south poles.
5. a position fix is a pair of geographic coordinates.
6. if the north arrow on a map points to the left, you would expect longitude lines to be vertical and latitude lines to be horizontal.
7. all map projections can show the true shape of countries and their true sizes.
8. the terms gnomonic, cylindrical, and conic refer to the shapes of the projection surfaces for each kind of projection.
9. the steepness of a slope on a topographic map is indicated by the angle that a contour makes with the horizontal.
10. a map that shows the location of all the geysers in yellowstone national park is a thematic map.
11. geographic information system (gis) applications can be used only by specially trained persons.
12. gis mapping is more effective for complex analysis than standard maps because layers of thematic data can be displayed as needed.

Explanation:

1. Maps use various projections, not just oblique view for maximum coverage. So false.
2. A map scale of 1:50,000 means 1 unit on map represents 50,000 units on ground, while 1:300,000 means 1 unit on map represents 300,000 units on ground. So 1:50,000 is larger. True.
3. North, south, east and west are relative to the Earth's axis and are consistent globally. True.
4. Great - circles on a globe pass through the North and South Poles or are perpendicular to the equator. So false.
5. A position fix is indeed a pair of geographic coordinates (latitude and longitude). True.
6. If north arrow points left, the orientation of the map is changed and longitude and latitude lines won't be in the standard vertical - horizontal orientation. So false.
7. No single map projection can show true shape and true size simultaneously. So false.
8. Gnomonic, cylindrical, and conic are named after the shapes of the projection surfaces. True.
9. The steepness of a slope on a topographic map is indicated by contour line spacing, not the angle with the horizontal. So false.
10. A map showing the location of geysers in Yellowstone National Park is a thematic map as it focuses on a specific theme. True.
11. GIS applications can be used by a wide range of people with different levels of training. So false.
12. GIS mapping is more effective for complex analysis due to the ability to display thematic data layers as needed. True.
