MATERIAL USED : ArcMap 10.2
PROCEDURE
1.Open ArcMap 10.2 → click on blank template → hit ok or double click
2.To add image: Add image tab →locate image file → ok (Link for Practice Material Below)
Add the DEM DATA of TVM. (Add both DEM and boundary of TVM)
3.Shapefile → change to hollow
4.Extract tvm DEM by the mask
Spatial Analysis tool → Extraction → Extract by mask
Input – Dem Layer
Input Feature – Hollow Shapefile (Tvm_dist)
Output – Tvm_Dem
5.3D analyst → raster surface → contour
Input— DEM
Output – contour40
Contour interval 40
6.3D analyst → data management → TIN → Create TIN
Output – TIN_tvm40
Spacial reference → projected coordinate system → UTM → WGS1984 →
Northern Hemisphere →43N
Input – contour40 (Soft type = mass pint)
Input – TVM (high field -= none, SF type = Soft clip)
Ok
RESULT
