a) false northing

b) false westing

c) false easting

d) translational shift

5.When the overlapping area between two feature classes is identified and stored in a new file where the attributes of only one of the feature classes is maintained, this function is called:

a) intersection

b) union

c) clip

d) dissolve

Explanation / Answer

1. a) their location on the surface of the earth has been determined.

Explanation : Spatial reference means georeferencing and describing where in the real world the features are exactly located.

2. c) Numberically.

Explanation : Human brain has the ability to perceive numerosity or the number of items or features in a map more accurately and precisely.

3. d) All of the above.

Explanation : Each font has an unique typer style and a definite type size and they belong to a specific type family. For example - a font of Arial type family has a 12 pt type size and a bold typer style.

4. d) Translational shift.

Explanation : Translational shift is the graph which is equivalent to shifting the base graph to the left or right in the direction of the x axis.

5. d) dissolve.

Explanation : The dissolve tool helps us to merge adjacent and overlapping polygons or lines or even multipoint feature classes of same type into a single class where only the attributes of only one of the feature classes is maintained.
