Motivations

The current configuration is based on:

• 4 input fields to define bounding box coordinates with a list of regions to quickly set up those 4 values.
• Bounding polygon could be define using GML object definition within the editor. But then user need to type coordinate of gmd:polygon elements manually.

The propsed change is to display a map in edit/view mode in order to be able to draw/display the metadata extent.

Proposal

Description

The map is in default WGS84 projection. In view mode:

• the map navigation is disabled
• the map zoom to the feature
• one map is displayed for each extent bounding polygon or bounding box.

In editing mode:

• a clear button allows to clear the feature on the map.
• navigation and mouse coordinate controls are available
• Bounding box
  • a draw rectangle tool is activated for bounding box.
  • the list of region is available to quickly define a bounding box and the description if available.
  • if more than one projection is defined in the configuration file, editor could display coordinates in another projection (does not change map projection, only form field content).
• Bounding polygon
  • a draw polygon tool is activated for bounding polygon

The config-gui.xml allows to define global parameters:

• map size
• list of projection (used to display bounding box coordinate in different projection.

Dependencies

New librairies are needed:

• OpenLayers
• ExtJS
• GeoExt

These libraries will be needed for Intermap to OpenLayers migration also. ExtJS could also be used instead of the modalBox lib.

...

Known improvements

• Change map projection.
• Select feature from WFS (on going)
