Building of a regular grid of vector characteristics

Previous Top Next

ic_0267 The given mode is used for building a regular grid of the vector characteristics presented by vector or dot objects of the specified kind. Construction is carried out with use of matrix data - matrixes of heights (MTW) or matrixes of qualities (MTQ).

The kind of created objects is set by pressing the button «…» or by pressing onto a window of display of object in group: Kind of created vectors.

The initial matrix of lengths (modules) of vectors and numerical semantics corresponding to length is set in Length of vectors group. The initial matrix of directions of vectors and the corresponding numerical semantics is set in Direction of vectors group. For construction of a regular grid of vector characteristics it is enough to set one initial matrix and semantics corresponding to it.

The regular grid of vector characteristics can be constructed onto region or onto the site of district specified in region. For building a regular grid onto region it is necessary to switch on All region mode in Output area group. For construction onto the preset rectangular site of district it is necessary to press the Select button in Output area group and to choose a site of district on a map by two click of the left mouse button. For change of borders of output area it is necessary to press the Change button and to execute change by mouse. For building a regular grid onto the site of district limited by the closed contour, it is necessary to press the By contour button in Output area group and to set a contour by clicks of the left mouse button. The termination of a mode of the specifying a contour and a mode of change is the double click of the left mouse button. For building a regular grid onto the site of the district limited by closed object, it is necessary to press the By object button in Output area group and to choose object by double click of the left mouse button. The quantity of created vector or dot objects (number of nodes of a regular grid) is defined by the specified output area and by the size of a step of the regular grid specified in Grid step (m) window.

The specified semantic characteristics of created objects are selected of corresponding matrixes by coordinates of nodes of a regular grid. Values of semantic characteristics at placing into created object can be transformed. The kind of transformation and used factors are set by pressing the Parameters of entering button in corresponding group.
