Comming soon in June, 2013

The goal is to have a set of mapping widgets that can be placed in different parts of a view to make different mapping applications easily using OpenLayers. other programming frameworks like Drupal have several mapping modules.

Proposed widgets:

-map -layer switcher -feature selector [data table grid] -query executor [an input field for query and sending results to openlayers via Ajax] -legend -Editor Panel -controllers [zoomer,panner,.....] -layout [ using JQuery UI Layout] -Data Exporter [exporting result sets to common GIS file formats like KML, GML, Excel e.t.c]

Requirements

-Yii 1.1 or above -PostgreSQL Database if using the Spatial Query Component

Usage

View file

// create layers:
$layerOSM =new OpenLayersLayer( "OSM", "OSM", array(
		"open streets",
		null,
		"params" => array(
				'transitionEffect' => 'resize',
		),

) );


// create Map and set options:


$map = new OpenLayersMap();
$map->setOptions( array(
		'controls' => array(
				'js:new OpenLayers.Control.Navigation()',
				'js:new OpenLayers.Control.PanZoomBar()',
				'js:new OpenLayers.Control.LayerSwitcher({div: document.getElementById("layerswitcher")})',
				'js:new OpenLayers.Control.Attribution()',
				'js:new OpenLayers.Control.MousePosition()',
				'js:new OpenLayers.Control.PanZoomBar()',
				'js:new OpenLayers.Control.OverviewMap()',
				'js:new OpenLayers.Control.KeyboardDefaults()',
				//'js:new OpenLayers.Control.EditingToolbar("vms")',

		),
		  'minExtent' => 'js:new OpenLayers.Bounds(-1, -1, 1, 1)',
		  'maxExtent' => 'js:new OpenLayers.Bounds(-20037508.3427892, -20037508.3427892, 20037508.3427892, 20037508.3427892)',
		  'numZoomLevels' => '18',
		  'maxResolution' => 156543.0339,
		  'units' => "m",
		  'projection' => "EPSG:900913",
		  'displayProjection' => 'js:new OpenLayers.Projection("EPSG:4326")',
	  	  'zoom' =>'2',
		  'center' => 'js:new OpenLayers.LonLat(0, 0)'
) );



$this->Widget( 'ext.mapping.MappingWidget', array(
      'grid_container_id' => 'grid-containerx',
      'map_container_id' => 'map',
      'layer_switcher_id' => 'layerswitcherx',
      'layers' => array( $layerOSM,$layerVector,$layerGOOGLE),
      'map' => $map,
      'htmlOptions' => array(
                             'style' => 'min-height:400px; min-width:200px; display: width:200px; height:100%; border:1px solid;',
                             ),
      );
