Can Google maps show contours?
Google Maps now has Terrain View, which enables users to see terrain maps for an area. Topographic contour lines are overlaid on the map to show elevation levels with altitude information displayed in gray numbers.
Who makes topographic maps in Australia?
Geoscience Australia’s National Geographic Information Group
Geoscience Australia’s National Geographic Information Group is the Australian Government’s national mapping agency.
How do you read a topographic map in Australia?
Lay your map flat and hold the compass above it and then turn the map to ensure the grid lines that run north (always top of the map) line up with the north point on your compass. You need to then shift your compass about 13º east, to adjust for magnetic north.
How far apart are contour lines on a map?
A contour is a line drawn on a map that joins points of equal height above sea level. For 1:25 000 scale maps the interval between contours is usually 5 metres, although in mountainous regions it may be 10 metres.
How do I get a topographic map on Google Maps?
How to find elevation on Google Maps in a web browser
- 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.
How do I get a topographic map on Google maps?
What is the purpose of topographic maps?
Topographic maps are a detailed record of a land area, giving geographic positions and elevations for both natural and man-made features. They show the shape of the land the mountains, valleys, and plains by means of brown contour lines (lines of equal elevation above sea level).
What are the types of maps?
Types of Maps
- General Reference (sometimes called planimetric maps)
- Topographic Maps.
- Thematic.
- Navigation Charts.
- Cadastral Maps and Plans.
What Cannot be shown on a topographic map?
A word of warning: topographic maps do not show every contour line, rather they choose sample of the lines. For example every 20, 50, 200 metres – depending on the scale of the map. This is called the contour interval of the map.
What are the symbols on a topographic map?
Topographic Map Legend and Symbols
- Brown lines – contours (note that intervals vary)
- Black lines – roads, railroads, trails, and boundaries.
- Red lines – survey lines (township, range, and section lines)
- Blue areas – streams and solid is for larger bodies of water.
- Green areas – vegetation, typically trees or dense foliage.
How are contours used on a topographic map?
Unlike to the Maphill’s physical map of Australia, topographic map uses contour lines instead of colors to show the shape of the surface. Contours are imaginary lines that join points of equal elevation. Contours lines make it possible to determine the height of mountains, depths of the ocean bottom, and steepness of slopes.
Is there any warranty for the contour map?
No warranty whatsoever is given, including but not limited to functioning or correctness. Resources: This script uses the Google Elevation API, Google Maps, jQuery and the CONREC contouring algorithm by Paul Bourke and Jason Davies.

How does a terrain map of Australia work?
Terrain map shows different physical features of the landscape. Unlike to the Maphill’s physical map of Australia, topographic map uses contour lines instead of colors to show the shape of the surface. Contours are imaginary lines that join points of equal elevation.
Are there any topographic maps available in Australia?
Please note that Geoscience Australia does not have 1:25 000 scale topographic maps in its collection. For availability of these maps please check with your local state mapping agency: Coverage: Partial coverage, predominantly in northern Australia, along major transport routes, and other selected areas.
