Eg. not just "all points in this range" but more complex shapes and queries. An analogue would be a comparison between the complex geospatial features in a modern database with geospatial support (eg. SQL Server 2008), and traditional non-geospatial SQL. Accuracy can be three things: positional accuracy (eg. X metres error), topological accuracy (eg. holes in polygons and shape relationships), and meta data accuracy (what a shape represents). Of course you need a certain degree of accuracy for a query to make sense - that is the same for all databases and all database queries. - Richard Marsden Mon, 24 Aug 2009 06:34:18 +0100 http://www.geowebguru.com/articles/99-overview-geodjango#comment-104 I wonder how a web app can do "complex spatial models and queries", since the accuracy of the Spatial DB´s involved in most times are unknown. Could you provide one or more examples ? Thnks, Luis - Luis Cunha Mon, 24 Aug 2009 04:39:32 +0100
