In other study areas such as the spring wheat regions of the
U.S. and Canada where long narrow fields are hard to distinguishand
where wheat can easily be confusedwith other spring-plantedcrops,
the accuracy goal was not met. Most importantly,however,LACIE
was able to determine the reasons for not meeting its goals in these
areas and to identifywhat would be needed to do so. Future satellites
with improvedresolutionshould allow smaller fields to be identified
with accuraciessimilar to that encounteredin the Soviet Union
where fields are typicallyquite large.
A peer evaluationteam composedof prominentscientistsand
chaired by Dr. Don Paarlberg,former Directorof Economics for USDA,
reviewed the LACIE techniquesand presentedtheir report at the sym-
posium. In the report, Dr. Paarlbergstated that, "LACIE results to
date clearly demonstratethat present remote-sensingcapabilities
can be combinedwith or substitutedfor conventionalmethods of
informationcollectionin order to improvecrop productionestimates."
He concludedthe evaluationof the results by saying, "... for global
wheat regions such as the U.S.S.R. the LACIE technologycan be made
operationaland that for regionswhere the technologyrequires improve-
ment, funding for further researchand developmentshould be continued."
NASA, USDA and NOAA which collectivelyprovidedthe many
differentskills necessaryto make LACIE a success are now defining
a follow-onactivity to extend the applicationof space-agetechnology
