How do topographic maps work in Canada?
Use location tracking to show where you are on the map, your elevation, and the accuracy of the GPS signal. Flags are included with map downloads. Add flags (waypoints) to the map to mark your current location or other locations. Import flags from other sources using GPX files and geocache LOC files.
Which data are shown on topographic maps?

What does 3r mean in topography?
Answer: 3r means the relative depth or height of the peninsular well or sand dune respectively is 3 m.
How accurate is elevation with GPS?
+/-400 feet
Elevation calibrated by GPS is accurate to +/-400 feet with a strong GPS signal. Elevation is determined by the device acquiring a GPS signal, while maps will provide elevation information based on survey data. GPS elevation readings may be different than elevations on maps or marked on trails and roads.
What is an NTS map?
The National Topographic System or NTS is the system used by Natural Resources Canada for providing general purpose topographic maps of the country. NTS maps are available in a variety of scales, the standard being 1:50,000 and 1:250,000 scales.
How accurate are topo maps?
Turns out, USGS topo maps use the National Map Accuracy Standards. This means that 90 percent of the horizontal points tested by field survey teams are accurate to within 40 feet. Vertical points, to within half a contour line, or five feet, based on standard 7.5 minute, 10-foot contour lines.
How do you show topography on Google Maps?
Type https://www.google.com/maps into your web browser on a Mac or PC.
- Type your location into the search bar on the left side.
- Click the “Menu” bar, which is next to the search bar and is represented by the three horizontal lines in the top-left.
- Hit “Terrain” to show topography and elevation.
Does the NTS cover all of Canada?
The Geospatial Centre has in its collection, the most recent editions of all three series of NTS maps. The 1:25,000 and 1:125,000 series has been discontinued and limited coverage is available. Please note that at the 1:50,000 scale, all of Canada is not mapped.
How do I read a NTS map?
The numbering begins in the southeast (lower right-hand) corner and zigzags to the northeast (upper right-hand) corner. This is the final element in an NTS map number for a 1:50 000 map. Note that certain maps do not conform to the regular National Topographic System (NTS) grid.
What are NRCan topographic maps?
Topographic maps produced by NRCan conform to the National Topographic System (NTS) of Canada. They are available in two standard scales: 1:50 000 and 1:250 000. Each map in this system has a unique number, which is a combination of numbers and letters. The area covered by a given mapsheet is determined by its location in Canada.
What is the size of a topographic map?
Topographic maps produced by NRCan conform to the National Topographic System (NTS) of Canada. They are available in two standard scales: 1:50 000 and 1:250 000.

Why do we use topographic maps?
Because they represent the earth’s features accurately and to scale, on a two-dimensional surface. This section provides information to facilitate the use of topographic maps, and also how to obtain paper and digital maps.
