3.6 Classification Code

In some past systems, classifications were assigned numeric codes. Numeric Codes have very little to do with the classifications, thereby making it very difficult to know which classification code to use with each land use. Furthermore, numeric codes limit additions to classification systems because once a series of numbers are fully exhausted the insertion of a new classification would require using an unassociated code. (See Table 3.6)

Table 3.6 Comparison of Numeric and Alphabetic Codes

Using the logical alphabetic codes, the user of the system will quickly learn to relate to and apply them. In the Nova Scotia Standard Land Use Classification System there are two letters assigned to each primary, secondary and tertiary level. These two letters when combined create a unique six letter code for the entire system. The majority of codes are easy to remember. In most cases, the code refers to the first two letters of the classification term in the primary, secondary and tertiary classes. (For example: Manufacturing - Processing - Agriculture: MA-PR-AG.) Where there is overlap, the code refers to the first two consonants. (For example: Residential : RS and Recreation: RC.) Where classifications have two or more words within each part of the hierarchy, the code refers to the first letter of the first two words. (For example: Residential - Mobile Home Park: RS-MH.) This system makes the codes easy to remember. It also makes it easier to insert new classifications at any point within the system. Subsequent levels of the classification can also be added using the same system
