Understanding Elevation on Google Earth
Elevation on Google Earth refers to the height of a point on the Earth’s surface above mean sea level. The elevation is critical in various fields, such as aviation, cartography, architecture, and environmental studies.
Types of Elevation Data
Google Earth uses several types of elevation data, which include:
- SRTM (Shuttle Radar Topography Mission) Data: High-resolution elevation data collected between 2000 and 2005.
- ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) Data: High-resolution elevation data collected between 2001 and 2004.
- ASTER GDEM (Global DEM): Global elevation data with a resolution of 1 arc-second (approximately 30 meters).
Tips and Tricks for Checking Elevation on Google Earth
Here are some tips and tricks to keeps in mind while checking elevation on Google Earth:
- Use the "Lock Compass" tool: The "Lock Compass" tool helps you maintain the geographical orientation, making it easier to read elevation data.
- Use the "3D Ruler" tool: The 3D Ruler tool provides accurate measurements in feet, meters, and other units.
- Use the "Elevation Profile" tool: The Elevation Profile tool shows the elevation changes along a specific route or path.
- Use the "Terrain" layer: The Terrain layer displays the 3D representation of the terrain, allowing you to visualize the elevation changes.
- Check the elevation accuracy: Different sources of elevation data may have varying levels of accuracy. Ensure you understand the data sources and limitations.
