Creation of a cost surface

Previous Top Next

ic_0261 This mode allows to build a cost surface (matrix of qualities). The value selected from semantics of area objects is put into a matrix element.

The semantics name should be selected by the user from the list of semantics numeric of map objects. At superposition onto a matrix element of several objects it is required to indicate the value which must be put into a matrix in the Select of semantics value mode: in centre of an element, minimum, maximum or in overall dimensions of an element. It is possible to fill objects absence on a map by numerical values for this purpose it is necessary to select fill the objects string in the appropriate mode and to enter the data in the Value of semantics window.        

The result is saved into the matrix map. The parameters of displaying are set in the dialog window: the number of displaying colors, their gradation in a given range are installed.

The accuracy of a matrix is indicated in meters in the Size element window.

Area of creation can be:

- all region held by a map;

- rectangular fragment.

 

The name of an Output file (matrix of qualities) is set automatically and consists of a map filename on which one the building was produced with addition of the extension *.mtq. The filename can be changed by user.

At successful completion of the building process it is offered to set a values range of a minimum and maximum really appropriated to the resulting data.
