MySQL supports spatial databases from 4.1 and complies with the OGC specification. The official version is 5.0.

5. PostgreSQLHttp://www.postgresql.orgChineseHttp://www.pgsqldb.org

PostgreSQL is an open-source database with the same name as MySQL. The latest version is 8.0. Through postgis middleware, PostgreSQL (version 7.4 and earlier) supports spatial databases.

6. postgis is also an open source projectHttp://postgis.refractions.net

7. Oracle database and Application SoftwareHttp://www.oracle.com

Oracle has been supporting spatial databases since 8 I. It currently has an absolute advantage in the commercial space database field.

Oracle 8i/9i provides SDO Java APIs for developers to read, write, convert, and analyze data. It also provides an Oracle 9i Application Server J2EE container Based on o9ias) server-client WebGIS application system example (to install this example, you must first install the Oracle 9i Database and o9ias Application Server. Your computer requires at least 1 GB of CPU and MB of memory, it takes more than 1 GB of memory to run smoothly ). Note that the SDK Java API library of 9i has been upgraded to 10 Gb, and Oracle does not provide download. (This site downloads the API package API documentation development manual development example)
Note: The above SDO files are applicable to Oracle 8.1.7 to 9.2.x, and have not been tested for version 10.

In addition to the original SDO, the Oracle 10 Gb New Path Analysis and network topology analysis API packages are added, and the spatial routing engine based on the Oracle Application Server or the Oracle J2EE container is added, the API package and routing engine can be downloaded free of charge from the Oracle website. (to install the routing engine, you must first install the Oracle10g Database and the o10gas (or Solaris) application server, your computer requires at least 1 GB of CPU and MB of memory ). (Please download it from the official Oracle website)

It mainly implements space database encapsulation based on SQL Server 2005 CLR integration. Currently, a command line tool is provided to support data import of shape files and PostGIS.
Link: http://www.codeplex.com/MsSqlSpatial

5. IGeospatial
The goal of the IGeospatial-Open Geospatial Library is to provide an Open source GIS Development Library Based on the. NET Framework. Multiple OGC and ISO specifications will be implemented. We are currently porting JTS feature implementations to. NET.
Link: http://www.codeplex.com/iGeospatial

6. Appomattox
Appomattox is an open source GIS desktop system. The core is a platform-independent and easy-to-use graphical component that can be easily integrated into. NET/Mono applications. Currently, Appomattox supports GTK and Windows. Forms.
The Appomattox project also contains WorkBench. WorkBench is a desktop GIS system provided to end users. It can work in Windows and Linux, but its goal is the GNOME platform.
Link: http://www.appomattox-project.org/Main_Page
