GeoLens is an interactive visual analytics framework. GeoLens provides fast and expressive interactions with voluminous geo-spatial datasets. We provide an expressive visual query evaluation scheme to support advanced interactive visual analytics technique, such as brushing and linking. To achieve this, we designed and developed the Geohash based image tile generation algorithm that automatically adjusts the range of data to access based on the minimum acceptable size of the image tile.
