 # replace geohash encoded algorithm, and reduce required properties of CREATE TABLE. For example,
{code:java}
CREATE TABLE geoTable(
 timevalue BIGINT,
 longitude LONG,
 latitude LONG) COMMENT "This is a GeoTable"
 STORED AS carbondata
 TBLPROPERTIES ($customProperties 'SPATIAL_INDEX'='mygeohash',
 'SPATIAL_INDEX.mygeohash.type'='geohash',
 'SPATIAL_INDEX.mygeohash.sourcecolumns'='longitude, latitude',
 'SPATIAL_INDEX.mygeohash.originLatitude'='39.832277',
 'SPATIAL_INDEX.mygeohash.gridSize'='50',
 'SPATIAL_INDEX.mygeohash.conversionRatio'='1000000') {code}

 # add some geo spatial UDFs,
{code:java}
// query filter UDFs {code}
