| vector data |
Vector
data type uses geometries such as points, lines (series of point
coordinates), or polygons, also called areas (shapes bounded by lines),
to represent objects. Examples include property boundaries for a
housing subdivision represented as polygons and well locations
represented as points. Vector features can be made to respect spatial
integrity through the application of topology rules such as 'polygons
must not overlap'. Vector data can also be used to represent
continuously varying phenomena. Contour lines and triangulated irregular networks (TIN) are used to represent elevation
or other continuously changing values. TINs record values at point
locations, which are connected by lines to form an irregular mesh of
triangles. The face of the triangles represent the terrain surface.
