Glossary for Geospatial Science

element: (vector) A vector object is made up of three different types of elements: 1) points, which are single coordinate pairs (or triplets) that define a point (such as a well); 2) lines, which are curvilinear strings of coordinates which define a curved line (such as a stream) and which have nodes at the ends and intersections of lines; and, 3) polygons, which are collections of lines which inscribe an area (such as a lake).
