Oracle Spatialis designed to make spatial data management easier and more natural to users oflocation-enabled applications and geographic information system (GIS)applications. When spatial data is stored in an
Oracle Spatialdoes not provide tools for spatial data collection, sophisticated analytical andvisualisation functionality provided by the traditional Geographic InformationSystems (GIS).
Spatial operators, such as SDO_FILTER and SDO_RELATE, provide optimumperformance because they use the spatial index. (Spatial operators require that the geometry column in the first parameter have a spatial index defined on it.) Spatialoperators must be used in the WHERE clause of a query. The...
Oracle Spatial addresses these issues for spatial data by providing an object data type (SDO_GEOMETRY), indexing capability, and functions/operators on SDO_GEOMETRY. It enables spatial data to be stored, accessed, and analyzed quickly and efficiently in an Oracle9i database. This gives application...
User-Defined Operators and Extensible IndexingIncreasingly, databases are being used to store more varied types of data, such as spatial, audio, or video data. This brings a need for indexing complex datatypes and for specialized indexing techniques. Oracle8i provides an interface that enables ...
Oracle Spatial Summit 2015 Tips • Be aware HINTS for Spatial Operators may be helpful. • Make sure geometries are valid. • Use SDO_UTIL.INTERIOR_POINT to avoid always calculating the greatest area of the intersection of overlapping polygons. • Analyze the different ways of writing a...
