On my site I\'m trying to get locations nearby. I\'m trying to use the Haversine formula for this. http://en.wikipedia.org/wiki/Haversine_formula
I have an SQLite database, which does not support trig functions.I would like to sort a set of la开发者_运维问答t,lng pairs in my table by distance as compared to a second lat,lng pair.I\'m familiar w
If I have two GPS locations, say 51.507222, -0.1275 and 48.856667, 2.350833, what formula could I use to calculate the distance between the two? I\'ve heard a lot about a haversine formula, but can\'t
I get Latitude and Longitudes from Google Maps Reverse-Geocoding API and then I need something like this:
I\'ve seen a number of people ask about this on Google Maps discussion groups to productive discussion, so I thought I would try here.
I want to search nearest locations from coordinates (lat/lng) into mysql database, I use spherical law of cosines to searching these places :
I\'m using OpenLayers with an ordinary mercator map and I\'m trying to sample a bounding box by finding a grid of points in latlong.
I\'m trying to convert spherical coordinates (namely latitude and longitude from a GPS device) into Cartesian coordinates. I\'m following this simple conversion derived from the polar coordinates conv
I have used the algorithm on http://www.movable-type.co.uk/scripts/latlong.html to find the distance between two points.
I understand how to get the distance between 2 CLLocations. I need to determine the generalized compass bearing (N, NE, E etc.) from a CLLocation to another CLLocation.
