Inside the triangle is your approximate current location. You should now have three lines drawn on your map, creating a small triangle where they cross one another. Repeat the steps you took to obtain a single back bearing for all three features you can see. It is possible to use just two features, but this will severely affect the accuracy of your pinpointing. The three features should be spread out, ideally with 120º between each (for example, one in front of you, one if you look over your right shoulder and the other over your left shoulder). If there are no man-made features use natural features such as the crests of hills, but be careful with trees and water, as these can change size and shape over time, making it easy to mis-identify them. You need to begin by taking the bearings of three features in sight, which are also on your map. TriangulationĪ resection is similar to a back bearing, but can be used if you are in the middle of open countryside or on an unknown track. Where the line crosses the track you are on is your approximate current location. If possible, draw a line along the base plate. Now carefully slide the compass across the map so one of the edges of the base plate crosses the feature you spotted on the landscape on the map. ![]() Line the orienting lines up with the eastings (the grid lines running north–south) on your map. The magnetic variation is currently 0º to 5º throughout Great Britain (this amount changes annually, so check your OS map to work out the most current value). To start, launch the Google Maps app on your phone. The app uses your phone’s location in conjunction with other data points to pinpoint your location on the map. You need to deduct magnetic variation from the compass reading to convert it. 01:13 View Your Location Now in Google Maps on Mobile On your iPhone, iPad, or Android phone, use the Google Maps app to find your whereabouts. I would also like that when I input the drivers location, the block (100-500) highlights or shows a pin of. Provide up to 26 locations and Route Planner will optimize, based on your preferences, to save you time and gas money. Right now it is very generic and I have the locations that I select to turn the color of the respected block. Identifying the degrees by 45 degree increments gives us the eight principal points of direction namely North (O or 360 degrees), North East (45 degrees), East (90 degrees), South East (135 degrees), South (180 degrees), South West (225 degrees), West (270 degrees), and North West (315 degrees). Route Planner can optimize your route so you spend less time driving and more time doing. ![]() This bearing is a magnetic bearing rather than a grid bearing, which your map uses. I am trying to show on a map the location of my drivers on a flight line when I input their location. On top of that, you can add as many layers as you wish by clicking on the Add layer option. And you can use the Base map button at the bottom to switch between different layers. You can use different layers to personalize the appearance of the map.
