Source image (LANDSAT TM) of this study
contained 7 spectral bands. For display purpose 3 bands
were selected which helped selection of training areas. For
this study R: 7 G: 4 B: 3 were found suitable.
In training stage location, size, shape and
orientation of each pixel type for each class was analysed to
categories the satellite image accordingly. Some regions
have been selected from Mirdita (district of Albania) area
for five land cover class through training process.
In classification stage each pixel was categorised into
land cover class to which it closely resembles. If the pixel
was not similar to the training data, then it was labelled as
unknown. Supervised classification of ER Mapper was used
for image classification. ‘Minimum Distance Classification’
was used as it gave best result among all supervised
classification available in ER Mapper. The land cover was
classified according to the FAO Land Cover Classification
System (LCCS) (Di Gregorio, A., & Jansen, L.J.M. 1996,
1997), a comprehensive, standardized a priori classification
system, created for mapping exercises and independent of
the scale or mapping method. The classification uses a set
of independent diagnostic criteria that allow correlation
with existing classifications and legends. The system could
therefore serve as an internationally agreed reference base
for land cover. The methodology is applicable at any scale
and is comprehensive in the sense that any land cover
identified anywhere in the world can be readily
accommodated.
Soil types and erosion features, obtained from
traditional sources, will linked to each land cover mapped
unit as attributes into a GIS system. This results in a
comprehensive database, which provides useful information
for agriculture, forestry and urban development planning,
for environment protection, and for many other
applications. The data collected in the database allow for
different kinds of spatial analyses, which are necessary in
land management. As the database developed using
ArcView, a common GIS software package, it will be easy
to combine the database with other data sets, existing or in
preparation, for a variety of different applications.
5. CONCLUSSIONS
In context of Albania, Remote Sensing technology is
an non well unexplored field. By using this rarely used tool
a land cover classification of Albania was done. LANDSAT
TM image was used for this study. The land cover was
classified according to the FAO Land Cover Classification
System (LCCS).
