Intro to GIS Final Exam
questions fully solved &
updated 2025
location errors - answer refer to the geometric
inaccuracies of digitized features and can be
examined by referring to the data source for
digitizing
topological errors - answer Violate the topological
relationships either required by a GIS package or
defined by the user
Topological Errors with Geometric Features -
answer undershoot, overshoot, dangling node,
pseudo node, direction error, label error
topological errors between layers - answer
boundaries not coincident, lines not connected at
end points, overlapping feature lines
Topological editing on coverages - answer editing
ensures that digitized spatial features
follow the topological relationships that are either
built into
, a data model or specified by the user
causes for digitizing errors - answer tracing, when
digitizer has unsteady hand
cluster tolerance - answer A geoprocessing
setting that forces nearby vertices to be snapped
together if they fall within a user-specified
distance.
Spatial data accuracy standards - answer 1.U.S.
National Map Accuracy Standard, revised and
adopted in 1947
2.Accuracy standards for large-scale maps
proposed by the American Society for
Photogrammetry and Remote Sensing in 1990
3.National Standard for Spatial Data Accuracy
established by the Federal Geographic Data
Committee in 1998
use of color - answer 1.Color has the visual
dimensions of hue, value, and chroma. Hue is the
quality that distinguishes one color from another.
Value is the lightness or darkness of a color.
Chroma refers to the richness, or brilliance, of a
color.
