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.<\/p>\n

Here are the file requirements.<\/p>\n

    \n
  1. It must be in a comma-separated value (.csv) format.<\/li>\n
  2. 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.<\/li>\n
  3. The maximum number of points it can import is 5,000.<\/li>\n<\/ol>\n

    For example, the following is a very simple but properly formatted file.<\/p>\n

    \"\"<\/p>\n

    To import, choose Import Point Cloud for Surface <\/strong>from the submenu of the TIN Surface button.<\/p>\n

    \"\" \"\"<\/p>\n

    Next, browse to the .csv file which contains your points and click [Open]. Channel Studio will parse the file and display the following screen.<\/p>\n

    \"\"<\/p>\n

    Select the headers which correspond to the X, Y and Elevation values from the drop-down list boxes. Then click [Import].<\/p>\n
