GeoBase is a

geospatial data for Canada. Through the GeoBase, users with an interest in geomatics have access to quality geospatial information at no cost and with unrestricted use.[1]

GeoBase Principles

These are the fundamental principles that GeoBase operates under and that direct the decision making process on a regular basis:

  1. Source, regional and—where practical—national data all share the same geometry.
  2. GeoBase provides national data coverages.
  3. Source data is collected once and used by many.
  4. Source data is collected and maintained closest to the source.
  5. The cost of maintenance and update is shared among the levels of government.
  6. All GeoBase data is available at no charge.
  7. GeoBase data has no restrictions on its subsequent use.
  8. 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. These 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.[2][3]

All GeoBase data must conform to the following technical characteristics:

  1. GeoBase data elements carry a unique and singular ID.
  2. GeoBase data comply with a standard data model and meet or exceed a minimum standard for accuracy, resolution, and currency.
  3. standardized at the entity
    level.
  4. GeoBase data and all associated tools adhere to
    international standards
    .
  5. GeoBase data is seamless across Canada.
  6. GeoBase data is consistent across layers.

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.[4] 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).[5]

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.[7]

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).[8]

Geopolitical Boundaries

This data layer contains the international, inter-provincial, and territorial boundaries, as well as the boundaries of Canada’s

cartographic purposes only. The dataset is composed of three files: an administrative boundary file, an administrative areas file, and a metadata file.[9]

Partners

The authoritative data source providers for this data layer are:

National Hydro Network

The NHN focuses on providing a quality geometric description and a set of basic attributes describing Canada’s inland surface waters. It provides geospatial digital data describing hydrographic features such as lakes, reservoirs, rivers, etc., as well as a linear drainage network and the

toponymic information (geographical names) associated to hydrography.[10]

Partners

GeoBase is joined by the following provincial/territorial partners for this data layer:

British Columbia Integrated Resource Operations - GeoBC
Quebec Ministère de l'Énergie et des Ressources naturelles Archived 2014-08-08 at the Wayback Machine
Yukon Highways and Public Works - Geomatics Yukon
Ontario Ministry of Natural Resources

Geodetic Network

The Canadian

Geodetic Network data has created a dynamic infrastructure to serve both present and future needs for positioning. As well as being a GPS control network, the Geodetic Network can serve as a monitoring network for deformation studies of the Canadian landmass.[11]

Satellite Orthoimages

GeoBase Orthoimage 2005–2010 is made from

orthoimages covering the Canadian landmass.[12]

The GeoBase SPOT 4 and SPOT 5 orthoimagery can be used in a wide variety of applications including:

intelligence, and security
.

GeoBase SPOT orthoimagery is aligned with, and can be integrated with, other GeoBase data layers. It can also be used in combination with other remotely sensed data.[13]

Partners

With funding support from GeoConnections, the following federal and provincial/territorial agencies jointly contributed to the production of the orthoimages:

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:

  1. Ensure that any theme added to GeoBase will meet the requirements of most Canadian geomatics data clients.
  2. Ensure that the data for the theme to be added is or will be available with some long term certainty.
  3. Ensure that data custodians and coordinators will adhere to the GeoBase principles.
