Problems solved by technology

At present, most of the applications in GIS systems are relational database systems. Relational data systems can only store two-dimensional data relationships. If multi-dimensional data relationships are encountered, data conversion is required to store them. This conversion will affect the development of GIS systems. cycle time and operating efficiency

Embodiment 1

[0017] The spatial database engine system of this embodiment should include the following components:

[0018] Datastore --- an in-memory cache for storing geospatial data;

[0019] Addressing component---a functional component used to parse out the data storage address according to the read instruction;

[0020] Data reading component --- read the data in the address after the addressing component is addressed;

[0021] Storage media --- installed in the computer to store data.

[0022] When a kind of spatial database engine system of the present embodiment carries out data operation, comprises the following steps:

[0023] Step 1: First, after summarizing the collected geospatial data information, it is gradually entered into the data storage area. The data storage area essentially records the corresponding address in the storage medium;

[0024] Step 2: While entering data, enter one piece of data each time, and store the address corresponding to the data in the addressi...

Abstract

The invention belongs to a data base system field and provides a spatial database engine system, especially one applied in geographic information system (GIS). The invention provides a spatial database engine system which can directly store three dimensional data of geographical space and does not need conversion; meanwhile the system can carry out operations such as direct reading and editing, etc. on three dimensional data. The invention realizes a direct storage of three dimensional geographic information data and provides a great database system support to GIS system.

Description

technical field [0001] The invention relates to a spatial database engine system, in particular to a spatial database system applied in a geographic information system (GIS), and belongs to the field of database systems. Background technique [0002] At present, with the development of information technology and the continuous expansion of application fields, geographic information system technology has developed rapidly. Since GIS is a strategic technology related to national security, it is of great significance to the development and application of my country's GIS to develop a domestic GIS system platform with independent intellectual property rights, to study and master the frontier key technologies in GIS. [0003] The development of the GIS system must rely on the collection of geographic data, and then summarize and organize the data, and establish a database to store the geographic data as the data support of the GIS system. At present, most of the applications in ...
