Create TIN

TINs or Triangulated Irregular Networks are three-dimensional planar items. A TIN is made of many triangular surfaces which connect adjacent points containing height attributes.

Each surface contains graduated height values (or a slope). Thus contour and/or flow themes can be superimposed on TINs. Smaller triangles give you greater detail.

TIP: TIN basically represents a surface model. It converts point data into a surface capable of displaying 3D visuals. You can handle large amounts of point data better as a TIN in 3D.

TINs can be created in one of three ways:
