10 Questions
What are spatial databases?
Spatial databases incorporate functionality that provides support for databases that keep track of objects in a multidimensional space. They store objects that have spatial characteristics and relationships among them.
Give an example of a two-dimensional spatial description database.
Cartographic databases that store maps include two-dimensional spatial descriptions of their objects.
What types of databases are three-dimensional?
Meteorological databases for weather information are three-dimensional, as temperatures and other meteorological information are related to three-dimensional spatial points.
What are measurement operations used for in spatial databases?
Measurement operations are used to measure global properties of single objects and to measure the relative position of different objects in terms of distance and direction.
What are spatial analysis operations used for in spatial databases?
Spatial analysis operations, often using statistical techniques, are used to uncover spatial relationships within and among mapped data layers.
What is the purpose of spatial databases?
Spatial databases store objects with spatial characteristics and relationships among them, optimized for storing and querying data related to objects in space.
What are some examples of databases that use spatial descriptions?
Cartographic databases that store maps and meteorological databases for weather information.
What are measurement operations used for in spatial databases?
Measurement operations are used to measure global properties of single objects and the relative position of different objects in terms of distance and direction.
What are common analytical operations in spatial databases?
Common analytical operations include measurement operations and spatial analysis operations.
How are spatial analysis operations typically conducted in spatial databases?
Spatial analysis operations often use statistical techniques to uncover spatial relationships within and among mapped data layers.
