All of the above

Answer 1

1. = Attribute Accuracy

Stating that a map "complies with national map accuracy standards" communicates is Attribute Accuracy.

2. = True

True. Data in a spaghetti data model maintains topological integrity.

3. = Transverse Mercator

Transverse Mercator is the map projection is the "official" map projection for projecting Colorado State Plane Coordinates.

4. B and C

NAD 83

NAD 27 can be useful for datum and that is used by GPS receivers when recording/collecting GPS coordinates.

5. = False

Verifying network topology is a form of quality control often conducted on a street network database is False.

6. = True

the raster data model is characterized by points, lines, and areas.

7. = True

All state plane coordinate systems are based on the same x-axis and y-axis origins making the system relatively seamless across the nation.

8.False

Calculating snowpack over a given geographic area based on data collected at sample points is a good example of using Thiessen polygons is False.

9. = National Geospatial-Intelligence Agency (NGA)

National Geospatial-Intelligence Agency (NGA) is the  United States federal agencies have responsibilities for creating and maintaining digital spatial data.
