For example “Canterbury Buildings Crop Tutorial Aug 2017.jar” (quicker) or “Canterbury Buildings.jar” (takes longer)
A filter decision tree is used to modify the asset data.
Construct a Modification Decision Tree
Drag an attribute (like “Floor Height”) to the filter box
Specify the parameters for example:
Enter “0.8” into the upper bound box for Floor Height. This creates two subsets of the data: • data with Floor height less than 0.8m ( from –ve infinity to 0.8m) • data with Floor height greater than 0.8m ( from 0.8m to infinity)
For the floor height greater than 0.8m specify no modification by dragging “no modification” to the decision box.
Drag “New modification” to the decision box for the floor height less than 0.8m
The asset modification tool will offer modification options.
Modify Attribute Values
Select “Floor Height” from the new modification drop down
Select the “Adjust Values by” toggle
- Enter 100 into the proportion field
- Enter 0.5 into the Mean
- Enter 0 into the Standard Deviation
The 100% only applies to the subset of the data that you have specified. for example: For the "adjust Values by" criteria using a criteria of "less than 0.8" and applying the above "new modification" to any buildings with floor heights less than 0.8m will add 0.5m to 100 percent of the buildings that meet this criteria.
If you select the "Set values to" toggle then 100 percent of the buildings with floor heights less than 0.8m will be set to have floor heights of 0.5m.
Select the filter that appears and click “OK”
Click the orange “Continue” button
