如何根据Google地图中标记的相对位置制作多边形？ [英] How would I make a polygon based on the relative positions of markers in google maps?

问题描述

我有一个标记列表，我想创建一个多边形（显示标记周围的区域而不是标记本身）。因此，不要让poly点是标记的直接纬度/长度，我希望poly可以围绕标记以显示它们周围的相对区域。

关于我如何能够完成这样的任何想法？ 这称为凸包 。 http://www.geocodezip.com/v3_map-markers_ConvexHull.asp 中有一个示例其使用在 http://softsurfer.com/Archive/algorithm_0203/algorithm_0203.htm

I have a list of markers that I want to create a polygon around (showing the area around the markers and not the markers themselves). So instead of having the poly points be the direct lat/long of the markers, I want the poly to "wrap" around the markers to show the relative area around them.

Any ideas on how I could accomplish something like this?

解决方案

This is called a convex hull. There's an example at http://www.geocodezip.com/v3_map-markers_ConvexHull.asp which uses the algorithm described at http://softsurfer.com/Archive/algorithm_0203/algorithm_0203.htm
