(PHP) Miles to Latitude and Miles to Longitude Converter - VisionHive

Sat, 01 Sep 2012 13:08:26 GMT

There are tons of functions out there to calculate the distance between two points, but what if you know one point and want to calculate the latitude ("vertical") or longitude ("horizontal") equivalent of a fixed distance, in miles? An example application would be in generating a minimum & maximum latitude and longitude bounding box around an area to limit the results of a database query that uses distance from a fixed point.

(JavaScript) Check if coordinates are adjacent - hellowouter

This function returns true if the two sets of coordinates are neighbors and false if they ar not. The function easily determines whether they are neighbors by looking at the distance between the positions along both axes, also callled the Manhattan distance. The sum of the two distances must be exactly 1 if the positions are adjacent. Note: the coordinates should be integers

(Objective C) How to find the distance between two CG points? - espinallab

Distance between p1 and p2: CGFloat xDist = (p2.x - p1.x); CGFloat yDist = (p2.y - p1.y); CGFloat distance = sqrt((xDist * xDist) + (yDist * yDist)); Background: Pythagorean theorem Edit: if you only need to calculate if the distance between the points increases or decreases, you can omit the sqrt() which will make it a little faster.

(JavaScript) Distance Between Two Points - parkerkrhoyt

Sun, 16 Jan 2011 04:24:08 GMT

This function will calculate the distance between two provided points. This is useful in game development when calculating paths of motion for sprites. The function expects two points to be provided. A point is defined as an object with an "x" and a "y" property. The result is a numeric value of the distance.

(JavaScript) Calculate distance between two points with latitude and longitude coordinates - ginoplusio

Sat, 26 Dec 2009 17:57:14 GMT

This function calculates distance with the Haversine formula, this formula assumes that our Earth is spherical, but it isn’t since it’s more like a big orange fruit also compresses at poles. I’ve read that this function has an error about + o – 3 meters (it depends), but it’s a small error for many purposes.

(JavaScript) Calculate distance on Google Map v3 with a ruler - ginoplusio

Sat, 19 Dec 2009 14:03:48 GMT

I’ve made a ruler to measure distances on a Google Map V3. The file Ruler.js contains a two function: one to calculate the distance between two points on the map with their position expressed in decimal degrees, and one function that add the ruler. Ther “ruler” is composed with two markers, a poly and two labels which show the distance. Look the link for a working demo.
