Geospatial Data

Canada’s economic, social and environmental well-being depends on the use of land, water, subterranean, atmospheric and human resources, for such things as farming, forestry, mining, transportation, tourism, coastal zone management, health, safety, economics and community services. Reliable access to geospatial data allows Canadian businesses, consumers, governments, academia and other non-governmental organizations to make better decisions about the products and services they provide to Canadians.

The Canadian Geospatial Data Infrastructure gives you access to geospatial information—in the form of data, maps and charts, satellite and airborne imagery, measurements, studies and publications as well as policy, standards, specifications and services.

Did you know?... The CGDI promotes the sharing and compatibility of geospatial data by defining a common set of framework data. Framework data is organized into layers, which consist of logically related geographic features and their attributes. There are three types of data layers:

  1. Alignment layers include geometric controls to position geospatial data.

  2. Land feature layers contain well-defined and readily observable natural or manmade physical features that are not subject to interpretation or speculation.

  3. Conceptual layers are the frameworks that society develops to describe and administer the country, such as municipal boundaries, federal electoral districts and ecological areas.
