Spatio-temporal data is graphic and image data that contains both space and time information. Spatio-temporal data consists of multidimensional information about objects, such as the location, shape, change, and size distribution.


Ganos is a spatio-temporal engine developed by Alibaba Cloud. Ganos supports a series of data types, functions, and stored procedures for Apsara PolarDB to store, index, query, analyze, and compute spatio-temporal data in a cost-effective manner.

This topic describes how to use Ganos in Apsara PolarDB to manage and analyze spatio-temporal data.
