- WHAT IS THE TIN SURFACE
The triangular irregular network (TIN) surface is a consisting of triangular faces of the triangular surfaces in the digital formate. The vertices of the triangles are created from field recorded surveying data. The survey is done by like as Total station survey, GPS RTK, PHOTOGRAMMETRY, etc.
In this article, I describe methods of creating a TIN surface from two software.
HOW TO CREATE TIN SURFACE FROM AutoCAD CIVIL 3D.
Open the AutoCAD civil 3d > Go to the new > Select in the file name- Autodesk Civil 3D (Metric) NCS.
> Select in files of type- Drawing Template(* DWT) > open
Go Home tab>Create ground data panel>Surface>Create surface.
A creation surface dialogue box is open, In the creation surface, the dialogue box changes the name in the dialogue box. like as surface OGL then OK.
After the surface is created, the surface name is displayed in the surface collection in the prospector tree, So that you can perform other operations, such as adding data and editing the surface.
Go to in the prospector tree.
Click on surface>Surface OGL>Click on the surface OGL> Definition>Click on definition>Right click on point files> ADD
After clicking on the ADD an Add point file dialogue box opens. Click the +Add file and select your file in the .csv format.
Then OK.
A tin surface is shown in contour type.
Go to surface OGL in prospector.
Right-click on Surface OGL >Select on edit surface style
In surface style dialogue box>Display
Then OK
HOW TO CREATE TIN SURFACE FROM ARC MAP
Open the new template of the Arc map.
Go to File>Add Data>Add XY data
Open an Add XY data dialogue box.
Select the field > OK
Open the Arc toolbox
Arc Tool box>3D Analyst tool>Data Management>Tin>Create Tin.
Create Tintable open to fill the requirement.
Then OK.
