Explanation
Kriging Method
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.

IDW(Inverse Distance Weighted) Method
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.
