Fig. 6.9 The classification of the major permanent, winter, and summer irrigated crops within
the irrigation projects in the ERB for the data of LANDSAT-TM acquired in May and August
2007
Table 6.4 presents the areas rates of the three broad existing classes (cultivated
areas, uncultivated areas, and water) and the various agricultural features (per-
manent-, winter-, and summer-crops) within each adapted irrigation project bor-
ders for the time periods 1975, 1987, 2005, and 2007. Finally, this table presents
the total area of each above mentioned class within the whole adapted borders of
the different irrigation projects for the same four time periods (see too Tables 6.2
and 6.3 ).
6.2 Accuracy Assessment Comparisons
Table 6.5 shows the final comparison between the various accuracies of classifi-
cation results. There was no classification achieved for the class/es with no
accuracy value/s (e.g., alfalfa was included in the coverage of 1987 under broadly
cultivated, but later the cultivated alfalfa areas were very small, thus it was
included under the class of other crops). In general, the lower accuracies were
made using MSS-data, while the higher were found by using ASTER-data fused
