GEO类型的基本操作
- 添加坐标点
geoadd key longitude latitude member [longitude latitude member ...]
- 获取坐标点
geopos key member [member ...]
- 计算坐标点距离
geodist key member1 member1 [unit]
示例:
127.0.0.1:6379> geoadd geos 1 1 a
(integer) 1
127.0.0.1:6379> geoadd geos 2 2 b
(integer) 1
127.0.0.1:6379> geopos geos a
1) 1) "0.99999994039535522"
2) "0.99999945914297683"
127.0.0.1:6379> geodist geos a b
"157270.0561"
127.0.0.1:6379> geodist geos a b m
"157270.0561"
127.0.0.1:6379> geodist geos a b km
"157.2701"
- 根据坐标求范围内的数据
georadius key longitude latitude radius m|km|ft|mi [withcoord] [withdist] [withhash] [count count]
- 根据点求范围内数据
georadiusbymember key member radius m|km|ft|mi [withcoord] [withdist] [withhash] [count count]
- 获取指定点对应的坐标hash值
geohash key member [member ...]
Tips:
- redis应用与地理位置计算
