Can you calculate distance from latitude and longitude?
One of the most common ways to calculate distances using latitude and longitude is the haversine formula, which is used to measure distances on a sphere. This method uses spherical triangles and measures the sides and angles of each to calculate the distance between points.
How do you convert degrees to meters on a calculator?
At the equator for longitude and for latitude anywhere, the following approximations are valid:
- 1° = 111 km (or 60 nautical miles)
- 0.1° = 11.1 km.
- 0.01° = 1.11 km (2 decimals, km accuracy)
- 0.001° =111 m.
- 0.0001° = 11.1 m.
- 0.00001° = 1.11 m.
- 0.000001° = 0.11 m (7 decimals, cm accuracy)
Is there easy way to compare Lat and long?
Say I have a lat and long of a way point and a lat and long of a user is there an easy way to compare them to decide when to tell the user they are within a reasonably close distance of the way point? I realise reasonable is subject but is this easily do-able or still overly maths-y?
How to calculate the distance between two lats?
If the distances are small, you can use the linearized version: Δx = Rcos(θ)Δϕ, Δy = RΔθ, where x is east-west distance, θ is latitude (measured with zero at the equator), y is north-south distance, and ϕ is longitude. Then the distance is d = √Δx2 + Δy2 in whatever units you used for R.
Are there distance calcs for latitude and longitude?
The wikipedia entry states that the distance calcs are within 0.6m for 100km longitudinally and 1cm for 100km latitudinally but I have not verified this as anywhere near that accuracy is fine for my use. Latitudes and longitudes specify points, not distances, so your question is somewhat nonsensical.
How much is length in meters of 1° of latitude?
Length in meters of 1° of latitude = always 111.32 km Length in meters of 1° of longitude = 40075 km * cos (latitude) / 360
