TIN, the surface modeling package used to create, store,
analyze and display surface information. The acronym
TIN stands for Triangulated Irregular Network - a set
of adjacent, non-overlapping triangles computed from
irregularly spaced points with x, y coordinates and
z values. The TIN model stores the topological relationship
between triangles and their adjacent neighbors (i.e.,
which points define each triangle and which triangles
are adjacent to each other). This data structure allows
for the efficient generation of surface models for the
analysis and display of terrain and other types of surfaces.
The TIN software package consists of specialized Arc
and ArcPlot commands and AMLs which are completely integrated
with the entire Arc/Info Geographic Information System
