10.4.6.4 Connecting a Map Region with a Report Region
Connect a map region with a classic report region.
This topic explains how to connect a map region with a classic report so that whenever the map region changes (that is, moves or zooms in or out), the report region refreshes to reflect the change. In order to connect a map region with a report region, this example creates a page which includes the following:
- A map containing an object layer named
Earthquake Map
sourced from a local table namedEARTHQUAKE_TABLE
. - A classic report based on a SQL query also based on
EARTHQUAKE_TABLE
. - To sync the map with the report, a hidden page item used to maintain the current map status (also known as a bounding box). A bounding box (usually shortened to bbox) is an area defined by two longitudes and two latitudes.
- A dynamic action to refresh the report as the map display changes.
Note:
Because of a restrictions within Oracle Spatial, this example only works if the map shows less than half of the earth. Therefore, the report will not refresh for zoom levels 1 and 2 of the map. See Coordinate Systems (Spatial Reference Systems) in Oracle Spatial Developer's Guide.To connect map with a report region:
