1 Overview Many Canadian organizations that manage civic addresses require a current, accu- rate and complete standard to support their industries: emergency dispatch, disas- ter management, government services (e.g., taxation, land-use planning), postal delivery, navigation, etc. With new and sophisticated applications, address data spanning multiple jurisdictions is readily available. e National Emergency Number Association (NENA) has established the standard for emergency services—which this document supports. rough readiness assessments and consultation with Cana- dian municipalities, this document also stands as a guide for Next Generation 9-1-1 (NG9-1-1) readiness standards. At Esri Canada, we have prepared this document for mapping editors to assist them in representing address data through common standards and best practices. e goal for this document is to simplify the process of accurately configuring address data to meet the multitude of address data uses, as well as the specifications of emergency NG9-1-1 systems. 2 Civic Addressing Primary Addresses are assigned by local authorities with official street names and numbers. is includes any descriptors or other address components. Mapping edi- tors should represent these features as Site Address Points. In cases where multiple primary address points exist for a parcel or building, mapping editors should input these as individual point features, as there is no allowance for address ranges on a single, primary address, such as a range of unit numbers (i.e., 101–622). Typically for vertical buildings with a primary address, there are sub-addresses for individual residences or business units (e.g., suites, units). ese occur in apartment buildings or condominiums but may also occur in other locations such as basement suites. For NG9-1-1, this detailed address and sub-address information is critical to accurately locate a caller during an emergency incident inside a large building, such as a shopping centre. For additional locations on large properties, mapping editors may also assign site address points to accessible features, such as driveway entrances or delivery doors. ese point features are typically linked to large properties and to those properties' primary addresses (i.e., such as the Civic ID of a primary address). ese features can also serve as access points for these properties. ese additional locations are important to NG9-1-1 to accurately locate incidents where a primary or a sub-ad- dress are inaccessible. Examples of such incidents can be where a long or intricate driveway separates a building from its main road, or on a large parcel of land where the closest access may not be immediately obvious to emergency responders.
