Release plans

openwereld — Wed, 02 Nov 2005 19:50:37 +0000

Release 0.5?

Support for editing map features?

Release 0.4 (next)

Use maps from multiple WMS'es
Layer control widget
Support for saving and restoring of web map contexts
??

Release 0.3 (current)

Ruler uses map (world) coordinates instead of pixel coordinates
StaticField and ControlField can show formatted output
new ServerLegend widget when using PHPMapscript for the ServerMap
calls to server widgets (ServerMap, ServerLegend) are made 'sessionless' in the sense that they don't need session variables; this to prevent problems with different types of session when being called from e.g. the drupal carto module. A generated javascript variable contains the name of the map file in use for the client's session.

User manual of mappingwidgets

openwereld — Wed, 02 Nov 2005 19:15:31 +0000

The 'MappingWidgets' project is developing a framework for making simple clients to OpenGIS web mapping servers (WMS). In order to reach a good performance, the generated mapping code (this is the mix of javascript and xhtml) is cached by the smarty framework. The standard smarty framework is extended with plugins to convert widgets in a template into necessary code.

Standard web mapping / geography functionality is: zoom in, zoom out, pan, info, overview, full zoom history (first,previous,next,last) etc.

An equally important objective is that the framework must be suitable for integrating it with a CMS or Wiki environment, such as Drupal or Mediawiki. An integration of mappingwidgets with Drupal can be found as Carto module at the Drupal site.

To change the extent, select a tool button: zoom in, zoom out, pan/move, or info. The remaining buttons are for the whole area, a previous extent, or a following extent respectively. Note that a zoom area can also be defined by dragging an area in the overview map.
