The Toporama Web Map Service (Toporama WMS) of the Earth Sciences Sector (ESS) at Natural Resources Canada (NRCan) is an Internet service that is intended mainly for online map application users and developers. This service is compatible with OpenGIS® Consortium (OGC) (http://www.opengeospatial.org/) Web Map Service standards and specifications, version 1.1.1. Toporama WMS can be accessed at no cost and without restrictions according to the terms of the licence (http://www.geogratis.ca/geogratis/en/licence.jsp). Registration is optional, but is highly recommended to help users be better known and kept informed, and to improve service. The registration form is available on the GeoGratis Web (http://www.geogratis.ca/) site under the Register to users list section. This service can be used to build a customized map using the best baseline data from the ESS for a given scale. These data are known for being accurate and up-to-date. They are grouped together under 15 information themes developed, depending on the scale, using CanVec 1:50,000, the National Topographic Data Base (NTDB) 1:250,000 and baseline data from the Atlas of Canada.
The Limits layer represents Geopolitical Boundaries features such as the international boundary, the inter-provincial/territorial boundaries and the exclusive economic zones of Canada along with political divisions.
The Vegetation layer represents wooded areas covered by bushes and/or trees.
Built-up areas (builtup_areas)
The Built-up areas layer represents densely populated zones where buildings are so close together that, for cartographic purposes, they are represented by a built-up area outline.
Designated areas (designated_areas)
The Designated areas layer represents areas of the landmass that have a precise use or function (examples: campground, marina, cemetery, golf course, etc.).
The Hydrography layer represents the surface water network only.
The Hypsography layer represents elevation points and continuous lines formed by peaks of equal altitude used to describe the topography. Elevation of points and lines is always calculated from mean sea level.
Water saturated soils (water_saturated_soils)
The Water saturated soils layer represents the major categories of wetlands.
The Landforms layer represents certain natural geographic features resulting from glacier and permafrost activity.
The Constructions layer represents manmade structures and buildings.
Water features (water_features)
The Water features layer represents natural or manmade features that are found in or around water phenomenons.
Road network (road_network)
The Road network layer represents road segments, including ferries, used for travel by land vehicles.
The Railway layer represents the various structures required for the movement of trains and other rail-based vehicles.
Populated places (populated_places)
The Populated places layer describes populated areas where buildings are so close together that, for cartographic purpose, they are represented by a point.
The Structures layer represents manmade structures, including bridges, tunnels and footbridges used for travel by land vehicles, trains or individuals.
Power network (power_network)
The Power network layer represents the main structures used to transport electricity, oil and gas.
Feature names (feature_names)
The Feature names layer describes the official names assigned to various topographical phenomenons.
