Statistics onto surfaces |
|
|
To calculate statistics it is possible by clicking the Execute button. At change of the calculation area the statistics is calculated automatically. For entering into semantics of map objects of average, maximal or minimal value it is necessary to enable the option Record values in semantics of object (selected objects) and to choose a code of semantics for each value. Writing into the objects is carried out at calculation of statistics. By area of calculation it can be: - all area held by the initial matrix; - rectangular fragment; - arbitrary fragment; - contour of selected object; - fragment set by coordinates; - contours of selected objects.
The mode is available at presence of the open matrixes of qualities or heights. |
In the given mode the statistics of qualities matrix is calculated or matrixes of qualities(calculation of the absolute sum, sum of positive and negative values, of middle, of minimum and maximum values) and the histogram of a surface is building, where on a horizontal axis the quantity of ranges (equal to the number of colours in the graphic palette of a matrix) is marked, and on vertical axis the number of values in the given range is marked.
