LTLoadXYZ
​
LTLoadXYZ[file]
imports a delimited XYZ survey point file -- easting, northing, elevation -- and grids it into a terrain Association. Options include "Delimiter", "HasHeader", "GridSpacing", the column indices "ECol", "NCol" and "ZCol", and "NoDataValue", which defaults to -9999.
​
Details and Options
▪
The delimiter, the presence of a header line and the grid spacing are all detected automatically by default.
▪
Automatic grid spacing targets roughly one fiftieth of the shorter axis.
▪
Use LTXYZPointOverlay afterwards to see the raw survey points against the gridded surface.
​

Basic Examples  
(1)
Grid a comma-delimited survey file:
In[1]:=
terrain=
LTLoadXYZ
["survey.csv"]
Read a file whose columns are northing, easting, level:
In[2]:=
terrain=
LTLoadXYZ
["survey.txt","ECol"2,"NCol"1,"ZCol"3]
