Question 1

10 pts

One distinguishing characteristic of geographic data is that phenomena like terrain elevation,

soil type, and even property value tend to be similar among neighboring locations. This property

allows us to estimate unknown attribute values from nearby known values. What is the property

called? (10 pts)

Scale independence

Spatial dependence

Spectral reflectance

Sheer coincidence

Question 2

10 pts

One of the following statements is true. Which is it? (10 pts)

The most accurate coordinates take into account the Earth’s complex shape.

Angles and distances calculated using plane coordinates are more accurate than

angles and distances calculated with geographic coordinates.

Geographic coordinates are more precise than plane coordinates.

The only distortion-free way to transform geographic coordinates into plane

coordinates involves a set of mathematical formulae called map projections.

Question 5

10 pts

We studied three coordinate systems in this course: geographic coordinates, UTM coordinates,

and State Plane coordinates. Which, if any, of the three coordinate systems involve map

projections? (10 pts)

All three coordinate systems involve map projections.

The UTM and State Plane coordinate systems involve map projections.

The UTM coordinate system involves a map projection; specifically, the Universal

Transverse Mercator projection.

None...
