AnalyticDB for PostgreSQL spatial data analysis combat

Digital economy, data is a key means of production, and spatial information as an important set of attributes and a set of model features a broad consensus in the industry. Government level, after the United States 911, communications carriers to provide the relevant government departments (such as public security, transportation, emergency command, etc.) mobile phone location information is protected by law; social part of the industry, in particular, to GIS, transportation, logistics, meals, lodging, travel, auto driving, etc., are all strongly associated with the information space. As a result, the storage of spatial data, spatial query and analysis features such as standard databases, such as NOSQL of Redis / MongoDB, RDBMS's MySQL / SQLServer / Oracle and others have the appropriate module to support it, PostgreSQL core support Geometric geometry type providing points, lines, polygons, rectangles, circles, and other geometric storage, geometric transformation, determining spatial relationships (intersection, comprising, phase, etc.) function, the function module is relatively simple, and the characteristics of lack of use of coordinate transformation inelegant (not meet OGC specifications), PostgreSQL open source community to make up the core Geomet
