GeoBase Principles

These are the fundamental principles that GeoBase operates under and that direct the decision making process on a regular basis: # Source, regional and—where practical—national data all share the same geometry. # GeoBase provides national data coverages. # Source data is collected once and used by many. # Source data is collected and maintained closest to the source. # The cost of maintenance and update is shared among the levels of government. # All GeoBase data is available at no charge. # GeoBase data has no restrictions on its subsequent use. # GeoBase data uses a common license.

Data Layers

Provincial, territorial, and municipal stakeholders agreed to work together to ensure the availability of high-quality geospatial data covering the entire Canadian landmass. This data is collected once and maintained closest to the source and provided free through the GeoBase with no restrictions for users. GeoBase has partnerships with federal, provincial, territorial, municipal government, and private companies, with the dual goals of eliminating data duplication and optimizing collectively available resources. GeoBase partners are involved in different levels of the data production process such as project funding, sharing of source data or by working on data collection and data processing.GeoBase - Partners List

Geographical Names Data Base

The purpose of this layer is to store names and their attributes that have been approved by the Geographical Names Board of Canada (GNBC) and to make these authoritative records available for government and public use. These records include the names of over 70,000 populated places and administrative areas; 300,000 water features; and 115,000 terrain features (e.g., mountains and peninsulas).

National Road Network

Since 2003, GeoBase has provided a consistent, accurate, and current NRN. The first edition of the NRN depicted the centerline of over 1.1 million kilometers of non-restricted use roads in Canada. In the fall of 2007, the second edition of the NRN was launched. NRN 2.0 includes place names, street names, and address ranges between intersections. Road network data provides the framework for many geomatics applications such as mapping, geocoding, geographic searching, and area delineations. NRN data can be used in a wide variety of activities, including managing road operations, business development and marketing, transportation, and government services delivery (e.g. census and elections).

New Data Layers

A process is required for the acceptance of a new data theme into GeoBase. The objectives of having such a process are: # Ensure that any theme added to GeoBase will meet the requirements of most Canadian geomatics data clients. # Ensure that the data for the theme to be added is or will be available with some long term certainty. # Ensure that data custodians and coordinators will adhere to the GeoBase principles.
