How can I connect to a PostGIS database from ArcMap using ArcGIS Desktop 9.3 and later?
I would like to be able to perform spatially enabled queries and receive the results back (e.g. spatial and non-spatial joins, filtering etc.) rather than just dumping the contents of a table.
I don't want to use the ArcSDE spatial extensions, I want to use the PostGIS spatial extensions in ArcGIS Desktop.
Answer
If you are using ArcGIS 10.0 or later, then you can directly connect to the PostGIS Data using a Query Layer, there is more information on this available in the help of each version:
To use the PostGIS geometry type, the database administrator must install PostGIS on the PostgreSQL database cluster. PostGIS is a third-party, open source installation. Once installed, the database administrator can use the PostGIS template database to create a database containing the PostGIS geometry type, or configure an existing database to use the PostGIS geometry type.
- 10.0 (this page may not view correctly in Chrome, so I have used IE to read)
