Description

Syntax for lod poi
lod poi [range] [zerocenter] [point_size] [contour_increment] [contour_values] [contour_aml] [color_filling_method] [solid_color] [show_all_points]
Arguments">Arguments
range min max
Specify data range to be used for color lookups. When not specified the range of the data is used.
zerocenter
Setting the data range to +- the maximum absoulute range of the dataset:
range_min = -max(abs(data_range_min), abs(data_range_max))
range_max = max(abs(data_range_min), abs(data_range_max))
point_size size
Size of the points to display. The default value is 1.0.
color_filling_method "solid" | "continous" | "discreet"
Specify the coloring method to be used for the grid surface.
"solid" - The same color everywhere. See the "solid_color" argument for how to specify the color.
"continous" - A color lookup table is used for coloring based on depth.
"discreet" - A single color is selected from the color lookup table for each region between the contour lines. The color is taken from the color lookup table.
contour_increment distance
Display evenly spaced color regions with distance in meters between regions.
contour_values num_values value1 .. value32
Explicitly specify the color regions.
num_values is an integer, valueXX are floats representing depth in meters.
contour_aml
Display color regions according to the Additional Military Layers specification:
For depths less than 100 meters the color regions are 5 meters tall.
For depths between 100 and 400 meters the color regions are 10 meters tall.
For depths greater than 400 meters the color regions are 20 meters tall.
solid_color r g b
Specify the color to be used with "solid" color display.
The RGB values should be between 0.0 and 1.0.
show_all_points
Always show all the points in the dataset.
Syntax for lod map
lod map [range] [zerocenter] [showfullresmesh] [contour_increment] [contour_values] [contour_aml] [color_filling_method] [solid_color] [show_contour_lines] [contour_line_color] [textures]
Arguments">Arguments
range min max
Specify data range to be used for color lookups. When not specified the range of the data is used.
zerocenter
Setting the data range to +- the maximum absoulute range of the dataset:
range_min = -max(abs(data_range_min), abs(data_range_max))
range_max = max(abs(data_range_min), abs(data_range_max))
showfullresmesh
Explanation-bla-bla with range [1, 2, 3 ..].
arg1
Explanation-bla-bla for arg1
arg2 red | blu | gre | pin | tur | yel | whi | bla | bro
Explanation-bla-bla for arg2 in color red / blue ...
arg3 [PointSize]
Explanation bla-bla- PointSize is a number larger than 0, relative to 1 (default), giving bla-bla.
Examples
Ex.1: Title-of-example
# read any grid xxx arg1 ;# Example bla bla pol ;# Display as polygon
Result of xxx on grid
