Summary

How to Run

[Base Mode]

Modify the surface using the Kriging method.

[Select Terrain Surface]
Select the terrain surface to modify.
[Select Point]
Select the points to use in the terrain modification process.
[Interpolation Method]
- Kriging Method : When finding the height of a specific point on the surface after correction, it is a method of interpolation using a linear combination of values around that point. It is a statistical method that minimizes variance by obtaining the Best Linear Unbiased Estimator (BLUE) of the minimum variance. Most commonly used.
[Parameter]
- Kriging Type : Select the interpolation method for the data.
  - Ordinary : The mean cannot be determined through Kriging, but the data is calibrated assuming that it is constant.
  - Simple : The data is calibrated by assuming that the mean is constant using simple Kriging.
  - Universal : The data is calibrated by considereing the tendency of mean in normal Kriging.
- Empirical Model : Variogram Modeling is used to define the regularity of the data that will be applied to Kriging. This is a method to estimate the closest theoretical curve.
- Interpolation Field
  - Relative Level : Use the relative height of the point from the selected terrain surface as the surface interpolation value.
  - Ansolute Level : Use the absolute level of the point as the surface interpolation value.

Linear : The points are interpolated as a straight line.
Spherical : The points are interpolated with linearly increasing tendency.
Exponential : The points are interpolated by conveging to a specific value.
Gaussian : The points are interpolated less in the vicinity and greater farther away.
Power : The points increase as the distance increases.
Hole-Effect : The points are interpolated by increasing at close range and by decreasing at a distance.
Wave : The points are interpolated in a waveform trend.
Rational Quadratic : The points are interpolated using a quadratic expression.
Circular : The points are interpolated using a trigonometric function.

[Option]
- Auto Resolution : Specifies the resolution automatically. If set to Off, the value can be entered manually, and if set to On, the terrain surface uses the existing resolution value.
[Preview Surface]
Preview the ground surface that will be created.

Modifies the surface using the IDW method.

[Select Terrain Surface]
Select the terrain surface to modify.
[Select Point]
Select the points to use in the terrain modification process.
[Interpolation Method]
- IDW(Inverse Distance Weighted) Method : When obtaining the height of a specific point on the surface after correction, it is a method of interpolating by giving a greater weight to the height of a point close to that point.
[Parameter]
- Distance Weight : When obtaining the height of a specific point on the surface after modification, a point that is farther away is reflected less than a point that is nearby. Sets the degree to which the reflection level decreases with distance.
- Affecting Radius : When obtaining the height of a specific surface point after modification, specify the range of data to consider.
- Interpolation Field
  - Relative Level : Use the relative height of the point from the selected terrain surface as the surface interpolation value.
  - Ansolute Level : Use the absolute level of the point as the surface interpolation value.
[Option]
- Auto Resolution : Specifies the resolution automatically. If set to Off, the value can be entered manually, and if set to On, the terrain surface uses the existing resolution value.
[Preview Surface]
Preview the ground surface that will be created.
