Designations must be mapped precisely. The requiring authority and the council should provide adequate and compatible mapping systems.  

Large-scale district plan maps or low accuracy GIS data can make it difficult to determine the extent of designations in relation to property boundaries which can result in errors when interpreting the plan. This is particularly important when the designation only applies to part of a site.  

Councils should work with requiring authorities at an early stage to ensure accurate, high-quality data and mapping is provided with notices of requirement and the recommendations and decisions on designations. 

The council should decide what the required size, scope, and standard of precision is required for the planning maps and GIS/ePlan systems and should signal at an early stage the required format for all mapping data. Large-scale designations (such as those in the rural area) and complex designations such as airport approach paths often require specific maps and explanations.
