My main view has several (perhaps many) polygonal active areas implemented as subviews. When the user touches the view, I want to identify if she hit one of those active areas.
We need to figure out a quick and fairly accurate method for point-in-polygon for lat/long values and polygons over google maps. After some research - came across some posts about mysql geometric exte
I have been trying to figure out how to write a simple program to compute the x,y points for creating a regular polygon of n sides. Can someone give me some code examples that don\'t use preexisting f
I have been looking at posts about determining if a point lies within a polygon or not and the answers are either too vague, abstract, or complex for me.So I am going to try to ask my question specifi
I\'m wondering what may be the most efficient way of determining whether a large number of points (O(1 million) are inside or outside a collection (O(10)) of polygons?The latter are not necessarily co
I have a map that I converted from a raster graphic into an SVG file by converting the di开发者_高级运维fferently coloured areas into paths.
So I have a map here 开发者_如何学编程 How can I, using Google Maps API, detect whether or not a given coordinate is within that polygon? Is that possible?
I need to read in a list of polygons from a Object File Format (.off) file (in c++). The format of .off files is basically like this:
I\'m using MySQL to pull lat longs from a database and check whether or not they are in a particular neighborhood.
I got the following stored procedure from http://dev.mysql.com/doc/refman/5.1/en/functions-that-test-spatial-relationships-between-geometries.html
