The length of a path drawn around the ring road of MRU is 1.55 km (see yellow path on image). Figure T5: Using the ruler tool to measure the length of a path, rather than a simple straight line. To return to the original view press the letter. Click clear to erase the line or path you measured. You can also hold down the shift key and use the right and left arrow keys on your keyboard to rotate the view. Notice that you can change the unit of measurement by using the drop down menu. Figure T5 shows a measured path along the ring road around MRU. You can also measure the length of a path, rather than just a straight line. This example shows that the length of two soccer fields at MRU is 151.47 m (see yellow line on map). The dialogue box will tell you the length of the line you are measuring. Figure T4: Using the ruler tool to measure distances in Google Earth. What distance did you measure? In Figure T4, the length of the line measured represents a real distance of 151.47 m. Click once to start measuring and click again to stop. Google Earth Pro - This current desktop version, now free to use, has many features, including displaying satellite and aerial imagery, a growing set of layers of mappable data, the ability to display third party data, tools for creating new data, and the ability to import GPS data. Google Earth is the most photorealistic, digital version of our planet. Let’s use a line to measure the length of the two soccer fields at MRU. Google Earth Pro on desktop Create maps with advanced tools on PC, Mac, or Linux. A dialogue box should pop up (see Figure T4). In Figure T1 below, the entire length of the scale bar represents a real distance of 230 m, and each division along the scale bar represents a real distance of 57.5 m.Ĭlick on the ruler icon in the toolbar located at the top of the screen. A scale bar helps you determine the actual, on the ground, distance between points or along lines. The bar in the bottom left corner of the image shows the scale bar (inside the orange box in Figure T1). In Figure T1, north is toward the top of the image (in the direction of the blue arrow). In the top right corner, the compass shows which direction is north in the current view.The red place marker shows the name and the exact location of the place you typed into the search bar. Google Earth Pro is a flexible tool for a variety of applications thanks to the ability to import and export data as well as generate unique maps and visualizations.Let’s point out a few things you should know about Google Earth. I was looking for answers as to how accurate the Mean Sea Level reading is in the San Francisco Bay Area using Google Earth Pro (the numbers are similar, just in meters, on Google Earth), since I was calculating building and ground elevations for a drone shoot at Genentech in SFO airspace for FAA authorization. From what altitude are you looking down on MRU? Figure T1: Annotated Google Earth map view of Mount Royal University (MRU), highlighting where to find the location marker for MRU (red box), the scale bar (yellow box), and north (blue arrow and compass in upper right corner).
