WebGeohash neighborhoods. One unfortunate consequence of the geohash system is that, while geohashes that are lexicographically similar (e.g. wxyz01 and wxyz12) are certainly close to one another, the converse is not true – for example, 7gxyru and k58n2h are neighbors! Put another way, small movements on the globe occasionally have visually … Webgeohash.encode_int (latitude, longitude, bitDepth=52) Encode a pair of latitude and longitude values into a geohash integer. The third argument is optional, you can specify the bitDepth of this number, which affects the precision of the geohash but also must be used consistently when decoding. Bit depth must be even.

WebSo you should have an array of 9 ranges, each with a lower limit and and upper geohash limit (18 geohashes in total). These geohashes are still in that lower resolution from step 2.
