Generate geojson files for Apache ECharts (incubating) Map,base on mapshaper

基于mapshaper对geojson地图数据的坐标信息进行压缩编码，并提供可直接生成压缩编码后的echarts map数据格式

通过mapshaper-plus可以直接将shp格式数据转换为压缩后的echarts数据

Demo

https://giscafer.github.io/mapshaper-plus/

Description

介绍 ——mapshaper可以将多种数据格式（Shapefile, GeoJSON, TopoJSON 和 Zip files）导入后，对地图的编辑和导出（Shapefile, GeoJSON, TopoJSON, DSV, SVG），功能强大和简单易用。

mapshaper-plus是在mapshaper基础上拓展对地图坐标信息的压缩编码，很大程度上减小了文件的代码行数和字节大小：譬如一个贵州省的数据，原始的geojson数据会在30M左右，但在对坐标信息压缩编码后，仅为1.4M。

背景 ——在做echarts图表统计时，需要自制地图数据，但官方没有提供一个平台可以直接将shp文件转化为压缩后的json或js格式的地图文件，而mapshaper导出的json数据没有压缩，数据量过大。
