Methods and systems for clustering objects using Geohash grids. The clusters are typically displayed on an interactive map. A clustering module receives multiple objects having respective geo-information and derives clusters for the objects in respective grid cells of a given resolution level. The clustering is based on the geo-information of the objects at one or more resolution levels that are finer than the given resolution level. Clustering based on finer-resolution levels provides spatial information at a granularity that is unavailable at the given resolution level and therefore achieves clustering with improved accuracy. The geo-information may comprise a Geohash spatial index that specifies the geographic location in accordance with the Geohash system. |
