Deriving and implementing slope and aspect variables for TIN

This paper deals with Slope and Aspect variables with mathematical approach. A TIN connects a set of irregularly spaced (x,y,z) locations. In the first section it shows slope and aspect analysis method and algorithm. Then it shows the process to create slope and aspect from TIN Model. In the second section it creates a TIN model from various elevated points which becomes input to calculate slope and aspect of TIN. It explores some of the important concept of slope and aspect with its practical implementation in ArcGIS. In the last section it explains application area where this analysis is useful.
