TIN (through DEM Data)

Aim:

 To create a TIN Map  using DEM data sourced from public domain.

Procedure:

Step 1: Map Input

A Digital Elevation Data from USGS.GOV website. For this session SRTM data was chosen

The boundary shapefile of the location

Step 2: Map Processing

·         Confine the extent of the SRTM DEM Data to that of the location boundary, using Data Management -> Raster Processing -> Clip (Tool).

·         Create elevation Contours of the SRTM DEM data using Contour (Spatial Analyst) tool.

·         Create TIN (Spatial Analyst) from the Contour Map created in the previous step.

Step 3: Map Display

 The final Output map can be displayed with Map Elements and grid properties of Layout. For smoothing, remove Hard Edges from symbology of map layer.

 Conclusion:

A Triangular Irregular Network Map from DEM Data is created on ArcMap.
