WebGeohash是Gustavo Niemeyer发明的公共域地理编码系统,它将地理位置编码为一串由字母和数字组成的短字符串。 它是一种分层的空间数据结构,把空间细分为网格形状的桶,是被称为Z阶曲线和通常称为空间填充曲线的许多应用之一。 点在多维中的Z值是简单地通过交织其坐标值的二进制表示来计算的,如下图所示。 使用Geohash创建GeoID时,数据按 … WebAug 27, 2024 · Calculate the query geohash at bit depth 26 (this is the radius of 10 kms) Calculate the neighbors of the query geohash and create the 18 member array. The 18 members are the 8 neighbors returned from the C method plus the original query geohash and the remaining 9 are obtained by adding 1 to this array.
