| To change internal units, only SPAresabs should be changed to reflect the new numerical value of the old "real-world" distance (as represented with the previous units). Even if the application does not need to interchange data, SPAresabs may need to be changed so that the numbers used to represent distances are appropriate for the application. This shifts the dynamic range, but does not change its magnitude. | |||||
| When different systems share model data, they should agree on the "real-world" distance represented by SPAresabs. This means that they don't necessarily have to agree on the numeric value of SPAresabs, depending on the units being used. | |||||
