Loss in value on a grid map

Only to be complete, this further method shall be mentioned. Calculation of facade levels and building evaluation is the same as in the examples before. To present the result as a colored map a grid must be calculated. This is necessary because the grid points must already exist before you can allocate a value to a grid point calculated for a window with Object-Scan.

To save calculation time, this is best done with all roads switched off. Calculate the grid, e.g., with a spacing of 5 m. For evaluation use Grid| Object-Scan with the parameters and adjustments as shown:

Parameter settings to calculate the reduction in rent

The reduction in value for all buildings is added up in a window of 100 m x 100 m, normalized to 100 m² and attached with the grid point in the center. Then the window is moved one grid spacing and the same is repeated. At the end, modify the level range on dialog Grid|Appearance to display all values properly on the map.
