A measure is an array of numbers which represent useful information. As such, measures form the 'raw material' from which MAST reports are built

Measures are created by summarising raw data to conform with dimensions. When measures have been processed in this way, they provide users with information in a very efficient manner. Processed measures are stored in data cubes.


Measures in MAST

In MAST, a separate data cube is used to store each variety of commonly used road safety and demographic information. Each cube contains more than one useful measure.

The cubes and the useful measures they contain are:

  • Population cube
    • Sum of population

  1. Click the Series (Columns) tab
  2. Click the Measures button
  3. Clear the check box for the current measure
  4. Select the check box for the desired measure
  5. Click OK
