No, but you can do it if you have an aircraft in....
I remember one time I was at Defence and we got a call. It was a shipment going to Alaska, and it had gone missing along the coast highway. The guy just hadn't called in. So we called the local RCMP detachment and said, “Could you please drive the highway between here and here and just see if this truck is there?” The guy said, “Yes. I'll get back to you within at least two days.”
That gave me an idea of how big.... I'm an Ottawa boy. I drive from here to the Glebe; that's where I live. But when you start to get a sense of the size of the country and our ability to actually respond, to fly a thousand miles of road.... The RCMP said, “We patrol that road once every two weeks normally, but we'll send a guy out and he'll drive it for you today, but it's going to be days before you get an answer.” That's where if you had a UAV or a manned aircraft, but cost-effective, you could toss that thing up and have an answer in a few hours.
