classification with type2a image when spectral information
almost is absent (the one band only), and classes textures are
strongly marked.
At the same time Figure 4 presents sufficient advantages of
proposed complex nonparametric algorithm, which is based
upon first-order Haralick texture characteristics and
nonparametric optimization of feature space.
Besides, the investigation on the basis of time series
mutlispectral RS images for the Uymon steppe area are
conducted. The spatial resolution of RS data is 30 meters. The
major classes of the RS images are the agricultural land,
bushes, water, and vegetation.

Figure 5 shows the time series RS mages for 1998, 1999 and
2000. Figure 6 shows the fragments of forecast maps for 2001
Obtained by three various techniques: a) by the traditional
maximum likelihood classification without CA; b) by the
traditional maximum likelihood classification and ordinary CA;
€) by the proposed algorithms of advanced interpretation and
enhanced TS analysis.
Figure 6 shows that the best forecast map is in c) fragment. It is

CONCLUSIONS
Permanent improving of comprehensive satellite systems allow
to obtain more qualitative RS images of high resolution, which
might be effectively used for designing of thematic and forecast
maps. Increasing amount of information requires the
specialized processing, RS and mapping software, forecasting
land use/cover change models.
The approach to the designing algorithms for advanced
interpretation of RS images and on their basement including
GIS designing forecast maps is developed in the paper. The
proposed approach is based upon nonparametric statistical and
ANN classification using spectral and spatial features. To make
the forecasting more adequate it is proposed the approach with
use of high-order Markov chains and CA with optimal
neighborhood size.
The preliminary investigation results conducted with use of
model RS images and TS RS images for Uymon steppe area,
show high efficiency of the proposed approach and availability
of further research in that field.
