ABSTRACT
Digital Terrain Modeling, the TriangulatedIrregular Network (TIN) is a representation of asurface derived from irregularly spaced samplepoints and break line features. Paperdeals withthebasic concept of Delauney’s triangulation methodwith its practical approach in ArcGIS. The nextsection describesthe process toconvert mass pointsto TIN modelandexplores some of the basicsofTIN Model with their data structure.The lastsection gives clear idea aboutits advantages anddisadvantages over grid based model
