When points are imported into AutoPlotter, DTM surface is created. Using this surface, it is possible to obtain elevation value for any point on or near the surface. To know the elevation values, Analyze DTM points option under DTM menu is used. Northing and Easting of the points for which elevation is to be generated, can be given in multiple ways.
i. By selecting the points from editor
ii. By selecting the polyline from editor
iii. Directly by entering the values of X & Y in the sheet
After X & Y values are entered, Z value is generated based on its position. If the point lies within the surface, elevation value is interpolated and if the point lies outside the surface, nearby elevation value is displayed.
