OceanBase Database supports the construction, storage, and analysis of spatial data types of Geographic Information System (GIS). The supported spatial data types in OceanBase Database are as follows: GEOMETRY POINT LINESTRING POLYGON MULTIPOINT MULTILINESTRING MULTIPOLYGON GEOMETRYCOLLECTION Single-value ...
Database research in the last decade has increasingly focused on providing support for non-standard applications. One important domain refers to the representation and processing of spatial information, as needed, for example, in geographical information systems. Database systems with additional ...
while Raster Data is all about layers of imageries extracted from camera sensors. Spatial data that belongs to geographical and geological information is known as geospatial data. Relational Database Management Systems handle these geospatial data, and they are called as ...
Install one or all of these types in your database. To install the ST_Geometry type in PostgreSQL, place the st_geometry library in your PostgreSQL installation's lib directory. Next, use the Create Spatial Type geoprocessing tool to create the ST_Geometry type in the database. See Add ...
Spatial data objects The geometry and geography data types support 16 types of spatial data objects, or instance types. However, only 11 of these instance types are instantiable; you can create and work with these instances (or instantiate them) in a database. These instances derive certain ...

Data is stored in the form of nodes, edges, and properties in which node is equivalent to a record, the edge is a link between two nodes and properties are additional information added into the nodes. Example Neo4j, Azure Cosmos DB, SAP HANA, Sparksee, Oracle Spatial and Graph, OrientDB...
Some spatial data types hold single geometry values: GEOMETRY POINT LINESTRING POLYGON GEOMETRYcan store geometry values of any type. The other single-value types (POINT,LINESTRING, andPOLYGON) restrict their values to a particular geometry type. ...
Example: To create a table namedgeomthat has a column namedgthat can store values of any geometry type, use this statement: CREATETABLEgeom(gGEOMETRY); Columns with a spatial data type can have anSRIDattribute, to explicitly indicate the spatial reference system (SRS) for values stored in th...
It was designed to make efficient use of database resources, to be compatible with database features such as replication and partitioning, and to provide rapid access to spatial data. ST_Geometry itself is an abstract, noninstantiated superclass. However, its subclasses can be instantiated. An...
