Question 5

Which of the following is a drawback of vector maps?
A) They become blurry when enlarged.
B) They make straight lines appear distorted and irregular.
C) Their construction requires human involvement in most cases.
D) Their features cannot be readily identified by GIS applications.

Accepted Answer

Vector maps often require human involvement for their construction, as they are created by defining points, lines, and polygons to represent spatial features, which can be labor-intensive.

Question 6

Which of the following statements is true of raster maps?
A) They consist of points, lines, and shapes.
B) They become blurry when enlarged.
C) They do not distort straight lines.
D) They have features that are readily identifiable by GIS applications.

Accepted Answer

Raster maps are made up of a grid of cells or pixels, where each cell represents a specific value or feature. When enlarged, the pixels become more visible and the overall image becomes blurry. Straight lines can also appear jagged due to the pixelated nature of the map. However, raster maps do have features that are readily identifiable by GIS applications.

Question 7

Which of the following is part of a raster map?
A) points
B) pixels
C) lines
D) shapes

Accepted Answer

Raster maps are comprised of a matrix of pixels (short for "picture elements"), each containing a value that represents a specific location or feature on the map. Points, lines, and shapes are more commonly associated with vector maps.

Question 8

Which of the following users for GIS applications is involved in capturing geospatial data?
A) field personnel
B) business intelligence users
C) developers
D) operations personnel

Accepted Answer

Field personnel are typically responsible for capturing geospatial data, such as through surveying or using GPS devices. Business intelligence users, developers, and operations personnel may use this data or work with GIS applications in other ways, but they are not typically responsible for the initial data capture.

Question 9

Which of the following best defines a map projection?
A) It is the process of converting all location identifiers to a common scheme.
B) It is a technique that involves dividing the earth into 60 north-south segments.
C) It is a geographic boundary set up within a geographic information system.
D) It is a technique for placing locations on the surface of the earth onto a flat surface.

Accepted Answer

A map projection is a technique for transforming three-dimensional locations on the surface of the earth onto a two-dimensional flat surface, such as a map. This involves making sense of the curved surface of the earth in a way that can be represented on a flat surface, which inevitably requires some distortion, resulting in different types of map projections.

Question 10

A geographic information system (GIS)is an information system that captures,stores,analyzes,and displays ________ data.
A) geospatial
B) geosynchronous
C) geological
D) geometric

Accepted Answer

A GIS captures, stores, analyzes, and displays geospatial data, which is data that has a geographic component or location referenced to the Earth's surface. This can include information such as maps, satellite imagery, GPS data, and demographic data associated with specific geographic locations.

Question 11

Which of the following users for GIS applications employs GIS to help solve a problem?
A) developers

Question 15

Which of the following statements is true of vector maps?
A) They are easy to create.
B) Once created, they scale perfectly.
C) Their construction does not require any human involvement.
D) They consist of pixels, each of which has some value.

Accepted Answer

Vector maps are created using mathematical formulas that define geometric shapes such as lines, points, and polygons. Since they are created using mathematical formulas, they are infinitely scalable without losing any quality. The other options are incorrect because vector maps require expertise and human involvement to create, and they do not consist of pixels with values like a raster map.

Question 16

To construct a map,a GIS application needs to convert all location identifiers to a common scheme: This process is called ________.
A) geocoding
B) geocaching
C) point positioning
D) project mapping

Accepted Answer

Geocoding is the process of converting location identifiers (such as addresses, postal codes, or place names) to their corresponding geographic coordinates (longitude and latitude). This is a crucial step in constructing a map in a GIS application. Geocaching refers to the process of storing data temporarily in a cache for faster access, and is not directly related to map construction. Point positioning refers specifically to determining the position of a single point on a map, rather than the conversion of multiple location identifiers. Project mapping is a term that is not commonly used in GIS applications.

Question 17
