Interpolation with one position (constant values for a region)
Graphic
Legend
Explanation

Pictured above is the water level distribution according
to the specifications of an ipds file as per margin.
The default value is set to 1.0 m except for the whole region Schiermonnikoog.
For this region the position Schiermonnikoog sets the water level to 5.0 m. No interpolation is needed.

Interpolation with four positions

Explanation

Pictured above is the distribution of the sediment fraction
clay according to the specifications of an ipds file
as per margin. The default value is set to 0.2 (this means 20 percent)
except for the region Borkum. For this region the four positions
BorkumWest, BorkumEast, BorkumNorth and BorkumSouth
overwrite the default value. The values between the four positions
are interpolated.Please note that the position BorkumNorth makes no
specification for the sediment fraction clay, because clay doesn't occur at this position.
