check vehicle location inside or outside

JulieBiju — Mon, 08 Sep 2014 02:58:59 GMT

Hi all,

I need to do the below task. How can I do this?

we have a vehicle location with longitude and latitude values. In a map we created a special layer named geofenceLayer. I need to check when this vehicle is coming in and going out from this particular layer. Is it possible to do?

Hi Julie,

You can use Envelope.Intersects method.

Get your vehicle location extent and check if it is intersects with the geofecneLayer.

Something like this

Polygon geoFenceArea = geofenceLAyer.Graphics[0] as Polygon;

if(vehicleLocation.Extent.Intersects(geoFenceArea.Extent))

//The vehicle is in

else

//The vehicle is out

Hope this helps.

Thanks,

Asser
