The viewshed tool can be used for detecting and calculating viewpoints, measuring distances, and analyzing a 360’ line of sight with a color code 3D view mode. Demographic data is shown on thematic maps, more specifically media age, income, and education level for your state, country, census tract or block group. Google Earth Pro enables you to research properties by zooming in to view parcel boundaries and get information about the price sold, zoning, square feet and other details. In addition, you can perform area and radius measurements, determine the height of a building, and measure viewsheds. The program allows you to calculate the distance in feet, miles, kilometers, acres and other units of measurements. Google Earth Pro comes with the same features and imagery included in Google Earth, as well as an enhanced suite of options designed for business users, more specifically distance, area and 3D measurements, multiple layers, and video recording options.
