Setting a Spatial Scope

A spatial scope can be set on the Data Selector, which can be used to limit the query results using spatial filters. The spatial scope defines a bounding box or a set of polygons that should be used by any spatial filters set on individual data type views. The individual data type spatial filters are controlled using the Query Filter window for data types having one or more spatial attributes.

The Spatial Scope Selection window can be opened by clicking the Select Spatial Scope icon SelectSpatialScopeIcon.gif in the Data Selector tool bar. The Spatial Scope Selection window presents two ways of establishing a spatial filter scope.

Bounding Box Spatial Scope

Clicking the Bounding Box spatial scope option displays a window used to enter a bounding box. The bounding box must be defined relative to the desktop coordinate system preference. A button CoordinateSystemPreferenceIcon.gif is provided as a shortcut for opening the desktop coordinate system preference setting window. A desktop coordinate system preference must be selected before entering the bounding box. The bounding box can be entered once a coordinate system has been selected. It can be entered either by typing in a lower left corner point and an upper right corner point, or it can be entered by sending an OpenSpirit GIS feature selection event from any OpenSpirit enabled application that can send GIS events (for example, ArcGIS Desktop with TIBCO OpenSpirit Extension for ArcGIS, Petrel with TIBCO OpenSpirit Adapter for Petrel, and so on). A bounding box is calculated to encompass all of the features in the received GIS feature selection event.

GIS Feature Polygons Spatial Scope

Clicking the GIS Feature Polygons spatial scope option displays a window used to select one or more polygons to be used as the spatial scope. The polygons must be selected by sending an OpenSpirit GIS feature selection event containing polygon features from any OpenSpirit enabled application that can send GIS events. A desktop coordinate system preference must be set in order to enable listening for GIS feature events. An edit button CoordinateSystemPreferenceIcon.gif is provided as a shortcut for opening the desktop coordinate system preference setting window.

GIS event listening enabled once a coordinate system preference has been set. Polygon features from received events displayed in a table allowing individual polygon features to be selected for inclusion in the spatial scope.
