I\'ve decided to ask this question through examples.I tried to expla开发者_Go百科in the entire project but it seemed confusing if you weren\'t already working on the same project so here we go.
How can I calculate the latitude-longitude of a place, when the latitude-longitude information of its 3 nearby places, and the distances to the place are given?
I am trying to write a php function that calculates proximity between two points but I cant get it to work.
EDIT: And package for not geographical distance between two lan-long points, but distance by car, or foot (like this http://code.google.com/intl/sk/apis/maps/documentation/directions/) Travel mode - d
Given two rectangles with x, y, width, height in pixels and a rotation value in degrees -- how do I calculate the closest distance of their outlines toward each other?
Given a quaternion value, I开发者_开发技巧 would like to find its nearest neighbour in a set of quaternions. To do this, I clearly need a way to compare the \"distance\" between two quaternions. What
I\'ve written this query and it works, although it\'s a bit slow: SELECT name, (ST_Distance( ST_Transform( way,900913 ),ST_Transform( ST_GeomFromText(\'POINT (-6.2222 53.307)\',4326),900913 )))
I get Latitude and Longitudes from Google Maps Reverse-Geocoding API and then I need something like this:
开发者_如何学GoI was using following code to find distance between 2 points: CLLocation *location1 = [[CLLocation alloc] initWithLatitude:28.3636 longitude:-77.1212];
I have a \"social\" geographic aware application I\'m developing, and the million dollar question is how do I list a set of items that are \"within X miles\" of \"my location\" since there are million
