Does Google Earth show topography?

Google Earth isn’t a topo map. The elevation is built in. It is a digital representation of the real earth. Google Maps does have a Terrain layer that is like a topo map.

What do the colors on Google maps mean?

The Google maps traffic color legend means green has no traffic delays, orange medium traffic, and red means traffic delays. A darker red shows an even slower traffic speed or stationary vehicles.

How do I view terrain in Google Earth?

Explore the slope, elevation, and distance along a path.

1. Open Google Earth Pro.
2. Draw a path or open an existing path.
3. Click Edit. Show Elevation Profile.
4. An elevation profile will appear in the the lower half of the 3D Viewer. If your elevation measurement reads “0,” make sure the terrain layer is turned on.

Where can I find large scale contour data for the US?

Large scale contour intervals are variable across the United States depending on complexity of topography, and as contours are generated per US Topo quadrangle, lines may not match across quad boundaries. The National Map download client allows free downloads of public domain contour data in either Esri File Geodatabase or Shapefile formats.

What is USGS elevation contours service?

Service Description: The USGS Elevation Contours service from The National Map displays contours generated for the United States at various scales. Small-scale contours were created by USGS TNM from 1 arc-second data with 100-meter contours, and are visible at 1:600,000 and smaller scales.

What is a large scale contour on Topo?

Large scale contours are updated every quarter, and are created by USGS TNM for the 7.5′ 1:24,000-scale US Topo digital map series. These contours are derived from 1/3 arc-second or better resolution data, and are visible at scales 1:50,000 and larger.

What is the range of medium scale contours?

Medium-scale contours were created by USGS EROS from 1/3-arc-second data with 100-foot intervals, and are visible between 1:150,000 and 1:600,000. Additional medium-scale contours were created by USGS EROS from 1/3-arc-second data with 50-foot intervals, and are visible between 1:50,000 and 1:150,000.
