Memory Map Elevation Data
Elevation data for Memory Map is derived from Canadian 1:250,000 scale DEM files. These files are combined into the proprietary Memory Map .QED format.
- E90001 - British Columbia Elevation Data
- E90002 - Alberta Elevation Data
- E90003 - Saskatchewan Elevation Data
- E90004 - Manitoba Elevation Data
- E90005 - Ontario Elevation Data
- E90006 - Atlantic Provinces Elevation Data
- E90007 - Yukon and Western NWT Elevation Data
- E90008 - Canada Elevation Data (Derived from 1:1,000,000 Scale Data)
Loading Elevation Data
First you need to download and then load the Elevation Data into Memory Map, unless it has already been loaded.
- From the Map drop down menu select Elevation Data... and choose the file you previously downloaded.
- To view the map in 3D simply press the 3D icon at the top of the screen.
OziExplorer Elevation Data
Elevation data is available for free download for use with OziExplorer and Ozi3D. You can download any of the available elevation data from the www.geobase.ca website.
This elevation data has the following specifications: The Canadian Digital Elevation Data (CDED) consists of an ordered array of ground elevations at regularly spaced intervals. The source digital data for CDED is extracted from the hypsographic and hydrographic elements of the National Topographic Data Base (NTDB) at scales of 1:50 000 and 1:250 000 or various scaled positional data acquired from the provinces and territories.
The coverage for each CDED file corresponds to half an NTS (National Topographic System) map sheet. CDED, is comprised of a Western and an Eastern section, for each NTS map. Depending on the latitude of the CDED section, the grid spacing (based on geographic coordinates) vary in resolution from 0.75 to 3 arc seconds for the 1:50 000 NTS tiles, and from 3 to 12 arc seconds for the 1:250 000 NTS tiles respectively. A CDED file consists of elevation data relative to Mean Sea Level (MSL), based on the North American Datum 1983 (NAD83) horizontal reference datum.
For more details about using Elevation Data please see the full list of data available at the OziExplorer Height Data Information Page.
Memory Map Gazetteer Files
Use these two Gazetteer files to quickly find topographic or place name features and load the appropriate maps.
Searching with the Canadian Gazetteer
- From the Search drop down menu select Load Database then MMI File. Choose the file that you previously downloaded.
- To do a search using the Canadian Gazetteer, from the Search drop down menu select Find Place. Within this new window you can conduct your search and then View the desired Map.
Unfortunately as the map legend was typically printed on the reverse side of the topographic maps it is not included with each map. Please use the following file to identify the features on your maps. For even more information about the topographic maps please see the Government of Canada Topo 101 - Topographic Maps, The Basics
Etopo Digital Maps Index Maps
The following index maps can be used to help you identify where the topographic maps you are interested in are located.
Polychrome (Colour) Style Map
Polychrome is the name the Canadian Government gives to the standard colour topographic maps. These maps are most commonly found in Southern Canada
Monochrome (Black & White) Style Map
Monochrome is the name the Canadian Government gives to the standard black & white topographic maps. These maps are most commonly found in Northern Canada
1:50,000 Scale Map
Each map covers an area approximately 25km by 40km. These maps are ideal for hiking, walking, cycling, hunting and much more.
1:250,000 Scale Map
Each map covers an area approximately 100km by 160km. Covers the same area as 16 of the 1:50,000 scale maps. These maps give great detail for an overall view of the area you are interested in. Ideal for travelling larger distances on backroads.
Treed Areas with mountain and glaciers
Typical map showing the details of trees, mountains and glaciers.
Typical map showing the details of prairies, coulees and gullys.
Topographic Photo Map
Photomap is the name the Canadian Government gives to the maps that show both aerial photography and topographic information. These maps are few and far between and are most commonly found in some Northern Canada areas.
Typical map showing the details of islands, water and shipping routes.
