+ +The new GeoGig index (a revision-sharing QuadTree index) greatly improves performance for the two most common types of queries - spatial queries and attribute queries. + +For spatial searches, the QuadTree organization of the index makes for efficient retrieval of features. + +The most common types of attribute query (“only display Highway and Freeways”, “only display data marked between these two dates” ) is also optimized by storing Extra Attributes inside the QuadTree. When executing the query, GeoGig can use the extra information in the index to quickly filter out unneeded features. + +The end result is **much** faster query performance (and much less network traffic).
