Which of the following are GIS geoprocessing operations? Select all that apply
A. merging features layers based on common attributes
B. assigning attribute data to features.
C. intersecting multiple feature layers.
D. Creating a buffer along a liner feature. - correct answer B. assigning attribute data
to features.
C. intersecting multiple feature layers.
D. Creating a buffer along a liner feature.
Map ________ is the practice of showing different features at varying map scales.
A. Scaling
B. Cartographic design
C. layout
D. generalization - correct answer D. generalization
Map generalization is the art and science of varying feature density based on scale.
The larger scale the map, the more detail depicted; the smaller the scale the more
abstracted.
If a section borders a river, what do the red integers in the fraction aliquot parts
designate? - correct answer Their fractional aliquot identification by Lot number.
What is the angular field-of-view for a single lens camera with a 12" fixed focal length
and 18"x18" negative format?
A. 106Deg44'
B. 23Deg21'
C. 93Deg22'
D. 46Deg41' - correct answer C. 93Deg22'
alpha=2*Tan^-1((csqrt(2))/(2f))
c=negative format
f=fixed focal length

B. fractals
C. bare-earth raster grid
D. a series of non-overlapping triangles. - correct answer C. bare-earth raster grid
What are the arc and chord definition of the degrees of curvature for a curve with a
1000ft radius? - correct answer Arc definition: D=5729.58/R
Chord definition: R=50/(sin(D/2)) or
D=2Xsin^-1(50/R)
On an original subdivision plat, the north line of each lot in block one is 100.00 feet
long. A resurvey of the north line uncovers original monuments only at the block
corners and the distance between them is 398.60 feet. How is the deficiency handled? -
correct answer Make each lot (398.60/4)=99.65ft
Subdivisions are created simultaneously so are in equal standing. Since they are all
the same width, they lose the same amount.

A. Witness
B. Grantor
C. Grantee
D. Recorder - correct answer B. Grantor
Only the grantor is required to sign the deed.

affected due to curvature and refraction for the sight? - correct answer 3.086"/1000M
distance
or approx. 71mm
What's the radius of the Earth? - correct answer 6371KM

R=450'
A. 55
B. 110
C. 70
D. 35 - correct answer The central angle is the deflection angle between the two
tangent lines.
55+55-180=70
How do you find the central angle when given the radius and chord length? - correct
answer Central angle= I
LC=2Rsin(I/2) or I=2*sin^-1(LC/2R)
Each row of an attribute table: (select all that apply)
A. Consists of one or more fields, each field representing a specific attribute type/
B. Corresponds to a specific feature
C. Defines a features metadata.
D. Contains a feature's position info.rmation. - correct answer A. Consists of one or
more fields, each field representing a specific attribute type/
B. Corresponds to a specific feature
Features are spatial objects depicted in the graphic window. Attribute data is non-
spatial information about the features. These are arranged in a table with each row
corresponding to a particular feature.
Aerial photography incorporated into a GIS project generally uses
a(n)______________data structure.
A. Raster
B. Analog
C. Vector
D. attribute - correct answer A. Raster
Aerial images are scanned using a raster structure based uniformly sized grid cells.
Each cell is assigned a single color value representing the feature. The smaller the
grid cell the higher the resolution.
