Attribute (nonspatial) data describe characteristics of the geographic features represented such as the feature type, its name, abundance, and quantitative information [e.g., area (of a soil unit) and length (of a river)].F T Bantilan
It is an optionwhich provides integration of location with traditional relational attributedata for Internet and wireless location-based services. However, Oracle Spatialdoes not provide tools for spatial data collection, sophisticated analytical andvisualisation functionality provided by the traditional Geograph...
Oracle Spatial Topology and Network Data Modelsdescribes data types for the Oracle Spatial topology data model and network data model. 2.2.1SDO_GTYPE TheSDO_GTYPE attribute indicates the type of the geometry. Valid geometry types correspond to those specified in theGeometry Object Model for the O...

After you have loaded spatial data, you should create a spatial index on it to enable efficient query performance using the data.
6、ift (e.g., a trend surface)Spatial associationNature of Spatial DataSpatially referenced data “georeferenced” “attribute” data associated with location where matters Example: Spatial Objects points: x, y coordinates cities, stores, crimes, accidents lines: arcs, from node, to node road net...
Spatial data types store feature geometry that describes shape and location. The geometry of spatial features is compressed and stored in a binary field along with the attribute data that describe the feature. In addition, the database application code is extended so that typical queries using ...
Columns with a spatial data type can have anSRIDattribute, to explicitly indicate the spatial reference system (SRS) for values stored in the column. For example: CREATETABLEgeom(pPOINTSRID0,gGEOMETRYNOTNULLSRID4326); SPATIALindexes can be created on spatial columns if they areNOT NULLand have...

In order to ensure the quality of the spatial database, knots shall be created between the digital graphic lines; all the polygons shall be enclosed; the graphical data and attribute data shall be corresponded one to another respectively; and any graphic error that goes beyond the standard for...
