When developing android lbs positioning, you can get a point (longitude and latitude) that requires businesses to be located one kilometer nearby. All these businesses are in the local database and are marked with longitude and latitude, that is to obtain the distance betwee
The needs to be positioned to get the latitude and longitude and calculate the distance when doing the project, using HTML5 to obtain the latitude and longitude degree.
Calculation formula for distance between two degrees of latitud
A recent project: You need to query a site (known to the latitude and longitude of the site) within 500 meters of other sites. So, the first thing I think about is, for each record, go to traverse, with each point in the database to calculate distance, when the distance is less than 500 meters, think match. It does get the results, but the efficiency is extremely

1, theoretical support: if from the point of need to judge a ray and the number of focus of the polygon is odd, then the point in this polygon, otherwise the point outside this polygon. (Rays cannot intersect with polygon vertices)
2, Programming Ideas:
The idea of the program is to make a horizontal ray (parallel to the x-axis, to the x-axis) from point A to the left to determine whether there is a focus on each side.
