How does the imperial system work?
The constructs of the Imperial Map Referencing System is based upon a hierarchical system. Each imperial series fits into its “parent” system. Figure 3.3 provides an example of how the system is structured. Its naming conventions however are not completely bases upon a hierarchical system. All provincial imperial series can be referenced back to the older 1:24 000 scale imperial system. In the case of the province’s 1:4 800, 1:2 400, and 1:1 200 only the 1:2 400 and 1:1 200 series are hierarchical in nature (see Figure 3.4 for examples).
