== Overview ==

Add a !GeoExt map panel in order to draw and display on a map the bounding box or bounding polygon of an ISO 19139/119 metadata record.

== 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
  * 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
  * a draw circle tool
 

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)
