The relationship between the weather and the movement of the
phy. geomorphological structure can be shown with the use of
predictive statistic tools. In this way, a polynomial function has
amic, been computed for each one of the targets with a accuracy of +
re 5). 4 cm.
ound. This predictive technique allowed us to estimate:
is the * The position of a control point linked a specified
campaing in the job.
e The determination of the moment in which the
structure began to take shape or the future prediction
SED in which ther will be a moment without activity.
Actually, in our case, the predictive techniques are applied on fixed
and visible predictive targets prepared to take photographs from
it. the helicopters. Following this way, in the near future, the
t and photogrammetric study can be supervised with geodetic campaigns
afler two years; the positions can be computed because of the
raphs predictive theoretical application of temporary series. Therefore, it
arrow can be summarise that ground control points are not always
needed, and it is possible to reduce the amount of money for
> care ground surveying, if and only if, statistical procedures are
an on considered and used.
nded: Actually, the techniques which have been developed in this
project have been applied in the following glaciers: rock glacier
apart of Posets (Pyrenees-Spain), rock glacier of Corral del Veleta
'an be (Sierra Nevada-Spain) and white glacier Ventorrillo in the
volcano Popocatepelt (México).
