Interpolate Land Survey Data using St. Line Method - Help


Interpolates value with weighted average method,means interpolation is done with respect to distance of points from reference values.
All methods are seen in the menu: ESUrvey CADD->Interpolate using Straight Line Method

Interpolation Using Straight Line Method
1. Interpolate values at Mid Point of selected texts

Using the ‘ISM’ command, you can interpolate a point at the midpoint of the two selected elevation texts. The newly interpolated text value will be created in a layer called ‘Layer1’.

2. Interpolate values at given Point

Using the ‘ISP’ command, you can interpolate values i.e. elevations at a given point depending on any two elevation texts.

3. Interpolate N values between given points

N number of values can be interpolated in between selected texts using ‘ISN’ command. If you have two elevations at around 20 M distances and you wish to create 3 interpolated values between these two elevations. Use 'ISN' command and specify 3 as the number of elevations and ISN command will interpolate 3 elevations in between these selected reference elevations.

4. Interpolate values at a given Distance

ISD’ works similarly to ISN command.Here instead of number of items you need to specify the distance between interpolated values.
