Generation and mutual conversion of ArcGIS tin ground surface and grid ground surface

establish TIN surface ：
First save as CAD Loading contour and elevation point data in format ：


1： Find and create TIN Tools for .
2： Find the output address , And create an appropriate name .
3： Load contour data , And set the contour properties .
4： The height field is set to elevation,SF_type Set to hard_line（ Hard disconnection ）.
5 and 6： The height field is set to ：elevation,SF_type Set to mass_points( Discrete multipoint ).

As shown in the figure , Generate surface map , Very nice, huh .

Create grid ground surface （ Use elevation points and grid interpolation to generate ）：

1： Find the feature tool （ Under data management ）.
2： Find the feature break point to point tool , Then open the .
3： Belong to CAD Line data for .
4： Output address and naming .
5： Point type selection ALL.

As you can see from the diagram , The line has been converted to a point , Good graphics .

1： Find the merge function under the geoprocessing tool ( Compare the contour break point data with CAD Point data merge ).
2： Combine contour break point data with CAD Add in the data .
3： Output address and naming .
4： Delete some fields from the field map , Leave only elevation And elevation fields .

You can see the merged elevation point data , Picturesque .

1： Select tools through attributes , hold elevation Li Wei 0 Both equivalents are screened out .
2： The formula .
3： The highlighted points in the figure are the screened results .

1： View the selected features .
2、3： Pay the value of the elevation to elevation.

View results （ Yellow area ）.

1： Find the spline function method （ be located 3D Analysis tools ）, This step is to generate the original ground surface for grid interpolation .
2： Spline function method .
3： Enter point features ： High level .
4： Elevation value field ：elevation
5： Output address and naming .
6： Output pixel size ：10.
7：1.
8:12.

The results are as shown in the figure above , If you don't like the color, you can change it （ For example, below ）.

TIN Turn the grid to the ground surface ：

1： Find the conversion tool （ be located 3D Analysis tools ）.
2：TIN Turn grid , open .
3： Belong to TIN data .
4： Output address and , name , Other settings can remain the default .

As shown in the figure, the generated results .
Below is the surface rotation of the grid TIN：

1： Find the conversion tool （ Or in 3D Under the analysis of ）.
2： Out of the grid .
3： The grid turns TIN.
4： Input the original grid ground surface data .
5： Output and naming .
6:1.

Still picturesque .
