I've downloaded most of the rdrs now so I thought I'd have a play with the data.
This is an image of the South Pole, The area shown is about 200kmx200km. I haven't tried to be accurate with the vertical scale. Here's a contour map of the same area, the contour interval is 200m. |

Current orbits are good to 15-20m, so I am not surprised that the orbit errors show up at 5m resolution. We're working on it (for example, by developping new gravity field models), but 5m is currently not achievable. (For reference, the original requirement was 50m). Maybe after GRAIL gives us a perfect gravity field!
Also, keep in mind that each laser footprint is ~5m in diameter, so your maps will have very sparse coverage at those resolutions. |
