Overlaying KML polygons on Google/Yahoo maps

Action: Navigate Distance Measure area Use geodesic measures For distance measurements, the distances are computed as distances between projected longitude letitude coordinates between points. Note that the area measurements, geometries drawn are planar geometries and the metrics returned by the measure control are planar measures by default. If your map is in a geographic projection or you have the appropriate projection definitions to transform your geometries into geographic coordinates, you can set the `Use geodesic` property of the control to true to calculate geodesic measures instead of planar measures.

Combined Google/Yahoo base layers with overlayed region soils data (50% opacity).

Code for above example listed below:

 {WISroGIS center_lat='-6.858'|center_lon='37.559'| reprojectCenter='1'| width='100%'| height='400px'| layerswitcher=1| overview=0| permalink=0| zoom_level=8| mapoptions='maxExtent: new OpenLayers.Bounds(-20037508.34,-20037508.34,20037508.34,20037508.34), maxResolution: 156543.0399, units: "m", projection: new OpenLayers.Projection("EPSG:900913"), displayProjection: new OpenLayers.Projection("EPSG:4326")'|

baseLayer='Google("Google", {type: G_SATELLITE_MAP, "sphericalMercator": true})'|

baseLayer='Yahoo("Yahoo Hybrid",{type: YAHOO_MAP_HYB, "sphericalMercator": true})' |

kml='GML("KML overlay", "cache/region_soils.kml", {format: OpenLayers.Format.KML, formatOptions: {extractStyles: true, extractAttributes: true,maxDepth:2}, projection: new OpenLayers.Projection("EPSG:4326")},{opacity:0.50})'
