GGU-SETTLE: "Differential settlements" menu item

If settlements have been analysed in the current file, this menu item can be utilised to load the settlements from a previous analysis and to generate and visualise the difference or sum total from the old and the new data. The coordinates of the settlement points must be the same in both files. It is therefore useful to save the points of a first settlement analysis using the menu item "Evaluation/Save settlement points" to a file which is then used as the basis for a further settlement analysis. The following dialog box opens:

Select the old ".pkt" file using the "Load" button. The current data can be saved again using the "Save current" button, if this has not already been done via "Evaluation/Save settlement points". Select the type of difference or sum formation in the option box. The following options are available:

• "Current - loaded"

• "Loaded - current"

• "Current + loaded"

If a file has been loaded the "Display" button is active and the previously seen dialog box for contour type selection opens. Normal, coloured or 3D contour visualisation of differential settlements can then be generated (see description of contour visualisation).
