Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information

Purpose

The file represents the areas in the province in a Regional District, Municipality, Electoral Area, First Nation Reserves, Communities or parts thereof where an Evacuation Order or an Evacuation Alert has been issued. It is an aggregated product of these active orders and alerts issued by the Local Governments or First Nations in order to provide a Provincial overview of the extent of these in the Province as a whole.

Data Quality

The database is updated on an as needed basis where Geographical Information is required at a Provincial scale in order to support an emergency event. The Local Governments and First Nations are the custodians of these boundaries and where possible users should always consult them first for the information as there may be a lag time between when this database gets updated and when the Local Government or First Nation issues the order or alert. Data is obtained either through digitization of the information found on a printed document or it is consumed from a web mapping application into this single provincial overview of the data.

Lineage Statement

Data is updated on an as needed basis during an emergency event where a Provincial overview of the situation is required.

Dec 19, 2018: The model has been updated so that areas under the same order or alert are combined to display as a single area.
