The Canadian Geographical Names Database (CGNDB) is the database of Canada's geographical names, maintained by the secretariat of the Geographical Names Board of Canada (GNBC), part of Natural Resources Canada. Its purpose is to store names and their attributes that have been approved by the GNBC so, that these authoritative records are available for government and public use. The subset of CGNDB data offered through the Geogratis Portal for data extraction and visualization consists of current officially approved names, and is referred to as the Canadian Geographical Names, Level 1 (CGN1) dataset. Additional attributes for this dataset as well as information on formerly approved names are available through the Canadian Geographical Names Search Service at http://www.nrcan.gc.ca/earth-sciences/geography/place-names/9170. The geographic extent of this dataset is the Canadian landmass and water bodies. The temporal extent of the data is from 1897 to present.
