| Zusammenfassung |
| The study of snow coverage and how it varies due to climate change in a specific area for a
certain period provides extremely important results. Information on the snow cover and of its
changes is essential for both global scale in evaluating future climate change scenarios and
catchment scale for water resource management. To this direction, remote sensing has a
significant contribution as it offers rapidly, cost-effectively and in frequent time
intervals spectral information in a wide range of spatial scales that can be used in snow
analysis.
The "White Mountains" is the main mountain of Chania Prefecture, found in the
west part in Crete Island. This is the most mountainous and arid region of Crete
with shallow, poor, rocky and with steep slopes soils. The amount of precipitation
received on the higher parts of the mountain is more than 3000 mm per year. The snow
melting often delays until mid-June due to the low temperatures prevailing in the
mountains.
This mountain and its snow cover have been the subject of this study. The aim of the
study is to determine with the use of remote sensing and Geographical Information Systems
(GIS) the snow cover and its changes over the last 40 years in the area. Information extraction
on snow cover and its changes will be based on a time series analysis of earth observation
data applying the method of remote sensing - photo interpretation, assisted by a GIS that will
be developed to facilitate the data analysis.
Results from this study will be analyzed in comparison to other ancillary historical data
coming from environmental and global records for the site.
