It depends on the asset. With RADARSAT-2 we're measuring the topography, and we give that to you in 3-D to quite a high resolution. If we use another satellite system that has what's called Elban, which is a different frequency, it will penetrate and give you the water moisture down to just under a metre—to half a metre or three-quarters of a metre. So it depends what asset you're talking about. The highest resolutions are with optical, but they work only when it's not cloudy. In Canada, you have 50% cloud every day. RADARSAT works night and day, 24/7, because it doesn't worry about the content of the clouds. We have other instruments. We let the radar be stopped at the clouds, and that's called CloudSat. That's an American satellite, but it's our instrument that is at the heart of that satellite.
So all of these things put together can make a difference, but the only way they're really going to make a difference is if the data at level zero is free. Then the mining companies can get all the data at level zero, hire somebody who is value-added to put it all together, and give them an output they can use to make their exploration operations more efficient. This is a key point. Part of the data policy we're pursuing is to make raw data that comes from government-based satellites be free to the industry.
