Significance of the File
contains general steering data for the program NCPLOT.
File-Contents (in Catchwords)
steering data
- Block Program_Parameters: general steering data
- Key "Language" : Language preference for labels and texts:
- DE = German,
- EN = English.
- Key "Max_Read_Storage" : max. read only memory (in bytes) for analysis
- Key "Min_Water_Depth" : minimum water coverage in [m].
- Hint: The excluding of data from the presentation in case of low water coverage is only possible, if the variable to be displayed points in a certain way to a variable associated with the total water depth.
The CF-NetCDF output of UnTRIM programs fulfills this requirement.
The page NCPLOT: Min_Water_Depth illustrates the effect of this control parameter.
- Block Normalization_Transformation: normalization transformation (NTN)
Definition of an image section and description of the link between the world and image coordinates. The coordinates of the drawing area, the so-called NDC space, range from [0.0,0.0] to [1.0,1.0]. For an undistorted view of the area the representation scale in the X direction must match the scale in Y-direction (DWC / DNDC = const). Distorted representations are also possible.
In addition to the positioning of the map windows NTNs be used for legends and text windows. Legends can be arranged either horizontally or vertically.
- Key "Name" : unique name of this normalization transformation.
- Key "Transformation_Number" : unique number of this normalization transformation.
- Key "EPSG" : EPSG code of the data coordinates in the file.
- Key "EPSG_Window" : EPSG code of the plot projection.
- Key "Left_Lower_Window_Coordinates" : World coordinates (according to EPSG) the lower left corner of the projection window.
- Key "Right_Upper_Window_Coordinates" : World coordinates (according to EPSG) the upper right corner of the projection window.
- Key "Left_Lower_NDC_Coordinates" : Picture coordinates (NDC within [0.0,1.0]) the lower left corner of the projection window.
- Key "Right_Upper_NDC_Coordinates" : Picture coordinates (NDC within [0.0,1.0]) the upper right corner of the projection window.
