TDS Data screen
Use the TDS Data screen to import data collector files that were generated by surveying lasers or GPS systems so you don't have to digitize the existing elevations from the drawings.
You can import data collector files that are in the following formats:
Binary data, with a CR5 file extension
ASCII data, with an ASC file extension
ASCII data, with a TXT file extension
ASCII data files are comma-delimited files with 5 columns: Point number, Northing, Easting, Elevation, and Description.
An ASCII data file might look like this:
1,91873.060,1437.810,14.188,DEsc1
2,91864.670,1450.160,13.786,DEsc2
3,91857.470,1454.500,13.990,DEsc3
