Efficiently querying geospatial data, however, is a considerable challenge: because the data is two-dimensional (or sometimes, more), you can't use standard indexing techniques to query on position. Spatial indexes solve this through a variety of techniques. In this post, we'll cover several - quadtrees, geohashes (not to be confused with geohashing), and space-filling curves - and reveal how they're all interrelated."<br/> <p><strong>Tags:</strong> #algorithms #databases #geo #hilbertcurves #indexing #quadtrees #spatial</p> Fri, 04 Dec 2009 00:53:07 +0000 linkding-ssg:bookmark:12659 algorithms databases geo hilbertcurves indexing quadtrees spatial
