Interpolating

Before you interpolate, you should set a sensible value for the "Scale" entry in the building property grid. See section "The Property Grid" and the extra documentation about the interpolator settings. If you have measured all you wanted and transferred the data back to the PC, open the building file with the measuring data. Then go to "Interpolation" $\rightarrow$ "Start Interpolation". The interpolation process will take a while, you may follow the process while it steps through the floors of the building. After the interpolation has finished, you will see the interpolated map of each floor. The colors may differ, but the default setting is: green - good quality, red - bad quality. The darker the color of one point is, the more reliable its interpolation is.

If you want to know the interpolated quality of a special point on the floor plan, just put the mouse arrow over it. You will see a tool tip that shows the quality of this point. You can disable this behaviour by deselecting "View" $\rightarrow$ "Interpolated Quality".

You may now save the building for later use or changes. Note: You may choose between 4 interpolation methods in the "Interpolation" $\rightarrow$ "Method" menu, which are: constant, exponentiell, linear and square interpolation. Constant is the only method which does not need any stations set on the map.
