  <dc:description>&lt;p&gt;The geometry of the frame photograph whether taken from an aircraft or a satellite is well known and documented. Transforming photographs into maps is a relatively slow and expensive process which for many critical steps defies automation. A satellite offers the unique advantages of greater stability and uniform velocity over an aircraft. A sensing system in space can now provide imagery of mapping quality even though a continuous electro-optical imaging system is used instead of a mapping camera with its inherent high geometric fidelity.&lt;/p&gt;&lt;p&gt;&lt;br data-mce-bogus="1"&gt;&lt;/p&gt;</dc:description>
