如何从shapefile / kml生成编码多段线？

问题描述

我需要将shapefile / kml转换为某个项目的编码折线格式。有人知道一个简单的转换工具或代码可以达到相同的效果吗？ 您需要先将您的KML / SHP列入经纬度/长对列表。对于KML，您只需在编辑器中打开KML文件即可获得经纬度对。对于SHP，您可以先使用转换为KML。 然后，使用库，或者您可以使用。

I need to convert a shapefile/ kml to encoded polyline format for a certain project. Does anyone know of a simple conversion tool or code that achieves the same ?

解决方案

You'll first want to convert your KML/SHP to a list of lat/long pairs. For KML, you can simply open the KML file in an editor to get the lat/long pairs. For SHP, you can first use shp2kml to convert to KML.

Then, use the encoding library in the Maps API, or you can write your own encoder using the algorithm.
