EstimateElevation()

Summary

Calculates a spot elevation using a TIN.

 

Syntax

spot_height = EstimateElevation(tin t, coord point)

 

Argument	Contents
t	A TIN
point	A coord

 

Returns

A real value for the spot elevation.

 

Notes

• The elevation is estimated based on where the point falls in the triangulation.
• If the point doesn't fall within a triangle, the return value is null.
• The elevation is in the same units as used to create the triangulation.

 

Example

SetLayer("Airports")

airport_tin = CreateTriangulation("Airports|", {{"Field","Altitude"}})

spot_height = EstimateElevation(tin t, coord point)

ShowMessage("The spot height is " + String(spot_height))

 

Error Codes

Error Type	Meaning
Error	The TIN compound variable is null
