GIS Topology Flashcards
1
Q
Topology
A
Define and enforce
Spatial relationships and constraints
Between geographic features
Ensuring data integrity and consistency
Within a spatial dataset.
A set of rules
On how points, lines, and polygons share their geometry,
Validates the spatial relationship between neighboring and overlapping features
2
Q
Accuracy vs Precision
A
Precision: identifies the closeness of two or more measurements to each other.
Accuracy: the closeness of a measured value to a known value
3
Q
Silvers
A
Small, spurious gaps, often a result of imprecise digitization of features in GIS
4
Q
Overlaps
A
Polygons or lines that are on top of each other which could result in double counting areas
