- create 2 data banks, 1 for each zone system
- in each data bank, create an ensemble that will be used to define the correspondence between the 2 zone systems
- punch and read the matrices using this ensemble (further manipulations might be required)
While it is possible to increase most of the data bank dimensions by using the macro modifydb, it is not possible to increase the number of centroids. If this is necessary, the only solution is to create a new data bank with the new dimensions. Data from the previous data bank can then be imported using Module 1.31.
