Construction of isolines by surface

This mode allows to construct isolines by a surface (matrix of heights or a matrix of qualities). Formation of isolines is carried out in borders of one surface.

For construction of isolines the user should choose a file name of surface, set a name of output user map, specify names of formed objects and to set parameters of isolines construction.

When the flag is set Prompting of analytical structure the modification of the input surface is performed with the purpose of obtaining more smooth forms. The degree of updating a matrix is set by means of the corresponding element located in one line with a flag of operation. At an execution of this process the values in an initial surface are changed.

Smoothing of the metrics of isolines flag is used for giving the smooth forms to the constructed broken isolines, by adding the points of the metrics by a method of interpolation of their planned position.

The minimal value and the maximal value show real values and allow the user to be orientated in a choice of a step of building the isolines.

Into the dialog box The minimal length of isoline the value is entered which defines the minimal length of an isoline in millimeters on a map. All isolines which length is less than this value, are not written into the output file.

As a result of working the program the user map is created on which the generated isolines are located.

The task of constructing the isolines by surface is a special case of the task.

In this task the quantity of parameters of construction is less, also the control and the coordination of input matrix is not made.
