![]() Spot the second location of your choice and then left-click to place the second point. Now, hover around the global and when you spot a location you are looking for, left click on the mouse to place a point. You can confirm this if you see your cursor turn into a crosshair-like icon. Now, from the toolbar, click on the ruler button to enable the line drawing feature. Open the Google Earth application on your computer. So, if there are any operations you want to perform between any two or even three places on planet earth, this is how you set things up by drawing a line across them all – And scroll through the dates to see all the satellite images from different days of the year. Look for the date the picture was taken from the bottom left hand corner of the screen. The application itself allows you to navigate to and virtually visit any location on planet earth (except secret government locations of course), so literally, all the visitable places are accessible and available for selection, and all that remains, is to know how to draw a line between the two places in order to get the distance between them, and even an elevation profile if you so desire. To move from an aerial view to a view as if looking from the Earth, use the horizontal bar in the right hand corner. In order to calculate this length, the two things you need are the two places in question. The length of a path drawn around the ring road of MRU is 1.55 km (see yellow path on image).In one of our earlier tutorials, we showed you how to find out the distance between two places on earth using the ruler feature. Figure T5: Using the ruler tool to measure the length of a path, rather than a simple straight line. Click clear to erase the line or path you measured. 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. Let’s use a line to measure the length of the two soccer fields at MRU. A dialogue box should pop up (see Figure T4). You can measure a straight-line distance by clicking on your start point and then your end. Measure distances and areas in Google Earth. 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. Measuring with google earth - Measuring with google earth is a mathematical tool that helps to solve math equations. 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.Let’s point out a few things you should know about Google Earth. ![]() 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).
