- It seems it would be more feasable to take several pictures by the same
- satellite at slightly different locations and combine them
- electronically. I'm not sure I understand the limits of this but I've
- been led to beleive that it works. A similar method is being used with
- radio-telescopes, recording the information simultaneously at several
- sites and then combining the data to get better resolution.
