xlvecle / geohash-poly

geohash-poly

A tool written by kotlin for users who want to transform a GeoPolygon to a list of geohashes that cover it. You can use it in kotlin/java/scala or any other jvm languages.

帮助你获取地理多边形内所包含的geohash块，支持JVM系语言，kotlin/java/scala。

Options

• precision: precision of geohash, default is 7
• mode: {"center", "inside", "intersect"} mode of calculation, default is "center", it means the center of geohash within polygon
• threshold: if you choose "intersect" mode, you can set threshold to control the degree of intersection

选项

• precision: geohash精度，base32位数
• mode: 计算包含geohash块的模式，默认是center，计算规则为geohash块中心点在多边形内
• threshold: 如果你选择了'intersect'模式，那么可以提供一个阈值来用来控制geohash和多边形相交的程度
