Geographic Information System (GIS) - correct answer A computer system for capturing, storing, querying,
analyzing, and displaying geospatial data.
Geospatial data - correct answer Data that describe both the locations and characteristics of spatial features on
the Earth's surface.
Vector data model - correct answer A spatial data model that that uses points and their x-,y-coordinates to
construct spatial features of points, lines, and polygons.
Raster data model - correct answer A data model that uses a grid and cells to represent the spatial variation of
a feature.
Georelational data model - correct answer A vector data model that uses a split system to store to store
geometries and attributes.
Object-based data model - correct answer A data model that uses objects to organize spatial data and stores
geometries and attributes in a single system.
Topology - correct answer A subfield of mathematics, that when applied to GIS, ensures that the spatial
relationships between features are expressed explicitly.
Triangulated irregular network (TIN) - correct answer Composite vector data that approximate the terrain with
a set of nonoverlapping triangles.
