PostGIS

Read	Yes
Write	Yes

JMap Server can connect to PostGIS databases to extract spatial data and attributes that can be used as a spatial data source. The only special requirement is the presence of a numeric column with unique integer values to be used as element identifiers. An SQL query must be provided. This query will be executed to read the data and it can access one or many tables at the same time.

The connection to the database must be already configured. See Creating Databases for more information.

Parameters
Database	Select the PostGIS database to read the data from. It must already be configured in JMap Admin.
SQL query	Enter the SQL query used to extract geometries and attributes from the database.
Geometry table	Select the physical table that effectively contains the geometries. Pressing Load will retrieve the list of fields returned by the query. This is necessary for the rest of the configuration.
Geometry field	Select the field that contains the geometries.
Id field	Select a field that contains unique identifiers. Only integer fields are listed.
Creation time field	(Optional) If you want this data source to be editable by JMap, this field will show the creation date of each object. If no field is selected, the data can still be edited, but this information will not be maintained.
Modification date field	(Optional) If you want this data source to be editable by JMap, this field will contain the date each object was last modified. If no field is selected, the data can still be edited, but this information will not be maintained.
Author field	(Optional) If you want this data source to be editable by JMap, this field will either contain the name of the user who created each object or the name of the user who made the last change. If no field is selected, the data can still be edited, but this information will not be maintained.
