Thematic Data Earth Sciences Sector Natural Resources Canada Slide 10 Find a Place Database All official names in Canada are stored in the Geographical Names Section of Canada database (CGNDB). Each official name (place or physical feature) is assigned a unique identifier, e.g. Pictou County CBDUD.This identifer is used to obtain the feature extent from the WFS, based on the official name queried. This unique identifier is the primary key that relates the tables in the Find a Place Database (FAPD) together. Each table represents a feature type (e.g. river, census division) which contains the thematic attribute information from the Atlas of Canada database. The thematic

data is derived from Atlas thematic shapefiles. Earth Sciences Sector Natural Resources Canada 24 Feb 2020 Slide 11 Find a Place Next Steps ... 24 Feb 2020 Content Perspective: Add secondary names. Secondary names are non-official names, such as health districts, ecozones, etc.

Resolve issues of labelling/symbology. Add more thematic layers, e.g. drainage basins. Eventually, allow users to locate any place/feature on a thematic map. Locate places on different and appropriate scales, such as the 1: 1 million, and possibly topo-maps (1:250 000/1:50 000). Continually add more thematic data to FAPD.
