Feature Layers

Internal Features can be displayed on the Map.

These features can be Points, Lines or Polygons.

Features can be added to the Map, removed from the map or moved on the map interactively.

To do this via a single set of Controls means having a single Features Layer. This layer can be built up out of multiple Feature Groups.

Downside to this is that it is not possible to dynamically enable/disable individual FeatureGroups whilst viewing the map!

Feature Classes

Feature Classes can (optionally) define the Marker used to render a Feature.

These also provide the information for the popup when a Marker is selected.

  • this can contain fields from the original tables &/or an Edit button to enable editing those details.

Feature Groups

A Feature Group can be a Feature Class (e.g. 'Shelters' or 'Organisations') or can be a custom query.

(These same Feature Groups can also be used to publish data as GeoRSS or KML or download as GPX or KML)


The Marker used for the Features will be:

  • The Feature marker (if defined) <- to be added later, if desired.
  • The Feature Class marker (if defined)
  • The Default marker

We should provide an option to allow the Feature-Class icon to over-ride individual Feature Icons.
