JMap Spatial is the format used to store JMap’s spatial and descriptive data. It is based on the WKB format (http://en.wikipedia.org/wiki/Well-known_binary).
An existing JMap Spatial table may be used as a spatial data source or a new one can be created to receive data.
Click on Add table to create a new table in JMap Spatial format. You can also select an existing table and click on Edit table to change its name or structure.
When creating or editing a table, you can add new fields to the table in the User Attributes tab by clicking on and remove fields by clicking on .
A warning message appears if you use an SQL reserved word as an attribute name. You must change the attribute name.
Note that there are other fields in the table displayed on the System Attributes tab. These include geometry fields (vary according to geometry type), spatial index fields, and so on. These fields are created and populated automatically by JMap.
Once the table has been created or modified, it can be used for the spatial data source.
