Don’t have a LandXML-based TIN Surface? No problem. Channel Studio will make one for you. All you need is a simple comma-separated file containing X, Y, Z (or Easting, Northing, Elevation) points and the software will generate a TIN Surface. It uses a popular and well-known method called “Delaunay Triangulation”. The details of this procedure is beyond the scope of this user guide.
Here are the file requirements.
- It must be in a comma-separated value (.csv) format.
- It needs three columns containing X, Y and Z (Easting, Northing and Elevation) values. The first row should contain the column headers, followed by the X, Y Z values. The columns can be in any order, for example, Y, X, Z. The headers must be labeled as X or Easting, Y or Northing, Z or Elevation. Upper or lower case.
- The maximum number of points it can import is 5,000.
For example, the following is a very simple but properly formatted file.
To import, choose Import Point Cloud for Surface from the submenu of the TIN Surface button.
Next, browse to the .csv file which contains your points and click [Open]. Channel Studio will parse the file and display the following screen.
Select the headers which correspond to the X, Y and Elevation values from the drop-down list boxes. Then click [Import].
