Get the coordinates of a place. On your computer, open Google Maps. Right-click the place or area on the map. This will open a pop-up window. You can find your latitude and longitude in decimal format at the top. To copy the coordinates automatically, left click on the latitude and longitude.
Then the nominal precision of a longitude measurement at a given latitude is just determined by moving the decimal point; for example, at 40 degrees N, one degree of longitude is about 85 km and the precision of the first decimal at latitude 40 N therefore has a nominal precision of about 8.5 km.
Pour rechercher un lieu, saisissez les coordonnées GPS de latitude et de longitude sur Google Maps. Vous pouvez également obtenir les coordonnées des lieux que vous avez déjà trouvés. En plus de la longitude et la latitude, vous pouvez utiliser des Plus Codes pour partager un lieu sans l'adresse.
Using the field calculator, you can get x, y coordinates from points layer in any projection and make the conversion to longitude latitude. You can find the recipe , documented with formulas and an illustrated GIF.
Open Google Earth. In the Search box in the left-hand panel, enter coordinates using one of these formats: Decimal Degrees: such as 37.7°, -122.2°. Degrees, Minutes, Seconds: such as 37°25'19.07"N, 122°05'06.24"W. Google Earth zooms into that location and coordinates will be displayed in the lower right corner.
I am wanting to find a latitude and longitude point given a bearing, a distance, and a starting latitude and longitude. This appears to be the opposite of this question (Distance between lat/long points). I have already looked into the haversine formula and think it's approximation of the world is probably close enough.
On a non-Euclidean surface, as you point out, this cannot be the case. Nevertheless, a spherical or ellipsoidal surface can be defined by two coordinates, call them x/y or longitude/latitude as you wish. Begin at a given point on the surface, and rotate that point independently around two perpendicular axes of rotation. This yields a pair of ...
Given a latitude/longitude point anywhere on earth, I would like to assemble a polygon that roughly resembles a circle with a 100km radius around that point. It doesn't have to be pin-point accurate, just good to within a few hundred meters. I'd like to control the number of points returned (20 is probably fine).
The point layer that I am interested in is the first layer in my layer list. The coordinate values will be in the units of the spatial reference system of the layer. If your layer is in lat/lon, remember that x=lon and y=lat...
Find the fazi1 azimuth from the inverse geodesic to get the forward azimuth from p1 to the second point: p1 -> p2: 100.85701421; p1 -> MP: -2.90404662; So the absolute difference between these two azimuths should be the angle you are looking for, 103.76106083. And again, this is the angle between MP and p2 as "viewed" from p1.
