Spatial Analysis Exam 1 UPDATED Exam
Questions and CORRECT Answers
Cartographic rules of thumb - CORRECT ANSWER - 1. know your audience
2. understand what you are addressing
3. keep it simple
4. use design elements for emphasis
What are the two major types of maps? - CORRECT ANSWER - 1. General Reference:
large amount of spatial info, many different themes, emphasis on displaying a large amount of
data
2. Thematic Map: small amount of info, emphasizes one point, illustrates spatial relationships
What is the most powerful cartographic tool available? - CORRECT ANSWER - Color:
should have a relationship with the features it represents
When would you want to use labels instead of a legend? - CORRECT ANSWER - When
using points, polygons, or lines (labeling towns, counties, or rivers)
What are the basic components of a map layout? - CORRECT ANSWER - 1. title
2. map
3. legend
4. north arrow
5. source information
6. scale bar
Spatial Data Model - CORRECT ANSWER - a method of presenting real world objects in
GIS
, what are the two common types of Spatial data models? - CORRECT ANSWER - 1.
Vector: data represents discrete features (things on the ground with boundaries) with inherent
geometry such as points, lines, and polygons
2. Raster: a series of square cells ideal for representing a continuous surface characterized by cell
size or pixel value type
inherent geometry of a point - CORRECT ANSWER - X&Y coordinates
inherent geometry of a line - CORRECT ANSWER - made up of connected points, length,
nodes, and vertex coordinates
inherent geometry of polygon - CORRECT ANSWER - line/series of lines that encloses
an area, area, perimeter, centroid
fields - CORRECT ANSWER - (Column) store specific info for all features
records - CORRECT ANSWER - (row) store all information for each feature
implicit topology - CORRECT ANSWER - the origin of each raster layer is the upper left
most pixel
cell size - CORRECT ANSWER - the ground based dimension of a cell
three types of raster data layers - CORRECT ANSWER - 1. continuous
2. thematic
3. image
continuous raster - CORRECT ANSWER - pixel values represent a continuous pixel value
measurement across a surface, no attribute table (ocean temp map)
