Triangular irregular Network (TIN)

Aim:

To digitize contour points and extrapolate a Triangular irregular network map from them.  Visualization trough Arcscene  is also to be performed.

Procedure:

Step 1: Map Input

Create points of contour elevation and save them in the respective shapefile.  The contour elevation is computed from a known elevation value specified in the basemap or topographic sheet. 

Step 2: Map Processing

·         Use “Create TIN” tool to generate a TIN map from the contour point shapefile.

·         Use ArcScene, Software, to input the TIN map create through ArcMap.

·         In Z-values are not present, exaggerate vertical height through scene properties options available on scene layers of toolbar.

·         Use Animation, video options to view 3D mapping of the TIN Map layer.

Step 3: Map Display

Export Map to 2D from ArcScene and Export map to Jpeg format. 

Conclusion:

A TIN map from contour map points is generated in ArcMap and visualized in 3D format through ArcScene.
