GISP FINAL TEST 2026 QUESTIONS WITH
CORRECT ANSWERS GRADED A+
◍ A point in North America would have what values?.
Answer: Lat = Positive, Long= Negative
◍ What is an edge?.
Answer: Alternate name for a node (review definition)
◍ T or F: NAD83 State Planes are in meters, but states clarify which type of
feet should be used in their state..
Answer: True
◍ Contour Interval.
Answer: difference in elevation between contour lines
◍ CMYK.
Answer: The subtractive color system creates colors with the bases: Cyan,
magenta, yellow and black. The absence of all bases is white light.
Subtractive colors absorb parts of the light spectrum leaving the rest of the
spectrum behind. Mixing all subtractive colors creates black.
◍ What is the accuracy of a military grade GPS?.
Answer: 1mm to 1 meter
◍ When someone says "wire frame model", what are they referencing?.
Answer: TIN
◍ The raster calculator uses what syntax/language?.
Answer: Python
◍ What does SDE stand for?.
Answer: Spatial Database Engine
◍ Will a DEM pick out buildings, trees, and other distinct objects?.
, Answer: No. A Digital Elevation Model (DEM) is a representation of the
bare ground (bare earth) topographic surface of the Earth excluding trees,
buildings, and any other surface objects. A bare-earth elevation model is
particularly useful in hydrology, soils, and land use planning
◍ What is an XLS or XLSX file type?.
Answer: Microsoft Excel
◍ What is a web coverage service? What is it used for?.
Answer: For sharing raster data, can be used for analysis
◍ How much wider is the Earth at the equator?.
Answer: 27 miles
◍ What is this angle in South Azimuth? How do you measure it?.
Answer: 225Clockwise from South
◍ ASCII files are often delivered in what formats?.
Answer: .txt.dat.csv
◍ What projection is used for states that are elongated in the east-west
direction?.
Answer: Lambert Conformal Conic - TENNESSEE
◍ What units are used in US Coordinate Systems?.
Answer: Int'l FeetFeetMeters
◍ What level of accuracy is required by the 3DEP program?.
Answer: Q2
◍ Points east of the Prime Meridian have what value?.
Answer: Positive
◍ What are some examples of uncompressed raster formats?.
Answer: TIFF, GeoTIFF, Esri Grid
◍ What are the four kinds of distortion introduced by cartesian (projected)
coordinate systems?.
Answer: Area, Shape, Distance, Direction
,◍ What is ratio data? Give an example of ratio data..
Answer: Values a continuous phenomenon with a natural zero point.
Population, Distance, Rainfall - something with meaning when compared to
zero.
◍ What is a theodolite?.
Answer: a surveying instrument for measuring angles
◍ Arithmetic Operator: / means what?.
Answer: Division
◍ In a Venn Diagram of two circles, if the middle part is shaded, that
represents what function?.
Answer: AND
◍ Is State Plane a projection?.
Answer: NO, it is a Geographic Coordinate System.
◍ What is geodesign?.
Answer: Involving multiple professions, stakeholders, technology, data, and
techniques to design a solution to a spatial problem
◍ What is meant by temporal accuracy in raster data?.
Answer: Are the cell values correct for conditions during the time period it
was gathered?
◍ What is an .AUX or .AUX.XML file? What do they store?.
Answer: They are raster auxiliary files, they store information that a raster
cannot store (statistics, histogram, table, pyramid file, color map, etc)
◍ Swiss-Style.
Answer: A map style that combines various methods of terrain
representation such as relief shading, contouring, rock drawings and scree
patterns. Creates a 3D relief impression.
◍ What is the difference between signed and unsigned bits in a raster?.
Answer: Unsigned bits do not include a negative value. So a 256 bit raster
would go from 0-255A signed 8 bit raster would go from -128 to -127
, ◍ What is Galileo?.
Answer: Galileo is the European Space Agency's satellite navigation system
that is currently under construction.
◍ What is the difference between a geographic coordinate system and a
projected coordinate system?.
Answer: A geographic coordinate system (GCS) is a reference framework
that defines the locations of features on a model of the earth. It’s shaped like
a globe—spherical. Its units are angular, usually degrees.A projected
coordinate system (PCS) is flat. It contains a GCS, but it converts that GCS
into a flat surface, using math (the projection algorithm) and other
parameters. Its units are linear, most commonly in meters.
◍ Serif Fonts.
Answer: Have small lines at the end of strokes. Often used for geographic
features like mountains, ocean and lakes.
◍ Lines of equal value: A map showing thickness?.
Answer: Isopach (used in oil & gas, hydrologic survey)Shows areas of equal
thickness across a surface
◍ Arithmetic Operator: ** means what?.
Answer: Power
◍ What does == mean? What does != mean?.
Answer: Equal to, not equal to
◍ State plane is based on what spheroid?.
Answer: GRS_1980
◍ Planimetric Element.
Answer: A feature that is independent of elevation. Planimetric elements on
maps are often roads, buildings footprints, rivers and lakes.
◍ Photogrammetrists.
Answer: Find positions of features and the angles and distances between
them by measuring from photographs and analyze data to determine
