5 Questions
What is a spatial database and how is it different from a regular database?
A spatial database is a general-purpose database that has been enhanced to include spatial data that represents objects defined in a geometric space, along with tools for querying and analyzing such data. It is different from a regular database as it allows the representation and analysis of geometric objects and requires additional functionality to process spatial data types efficiently.
What are some examples of simple geometric objects that can be represented in a spatial database?
Some examples of simple geometric objects that can be represented in a spatial database are points, lines, and polygons.
What are some examples of more complex structures that can be handled by spatial databases?
Some examples of more complex structures that can be handled by spatial databases are 3D objects, topological coverages, linear networks, and triangulated irregular networks (TINs).
What is a geographic database (geodatabase) and what is it used for?
A geographic database (geodatabase) is a georeferenced spatial database used for storing and manipulating geographic data, especially in geographic information systems (GIS).
What additional functionality do spatial databases require to process spatial data types efficiently?
Spatial databases require additional functionality to process spatial data types efficiently, such as geometry or feature data types.
Study Notes
Spatial Databases
- A spatial database is a general-purpose database (usually relational) that stores spatial data representing objects in a geometric space.
- It includes tools for querying and analyzing spatial data.
Geometric Objects
- Spatial databases can represent simple geometric objects such as: • Points • Lines • Polygons
- Some spatial databases can handle more complex structures including: • 3D objects • Topological coverages • Linear networks • Triangulated irregular networks (TINs)
Data Types
- Typical databases manage numeric and character data types.
- Spatial databases require additional functionality to efficiently process spatial data types, including: • Geometry data types • Feature data types
Geographic Databases
- A geographic database (geodatabase) is a georeferenced spatial database used for storing and manipulating geographic data (geodata).
- It is often used in geographic information systems (GIS).
- Geodata is data associated with a location on Earth.
