Two quick points/questions...
(1) This certainly suggests a need for a cooperative remote sensing

(2) Is anything like a collaborative effort between the NAPL and the
National Library, National Archives, or (heaven forbid) any other
Canadian or foreign agencies with experience in such a project being
planned?
