Mongolia, as many countries of the developing world,
has problems with the urban expansion and the growth
of population in the main cities. For example, over the last
two decades, Ulaanbaatar, the capital city of Mongolia, has
experienced different urban related problems. In the city,
various problems had been previously accumulated during
the centralized economy, and they have been intensified by
the reforms of the entire political and economic systems,
unregulated market development, and the rapid population
growth caused mainly by migration from rural areas [1, 3].
To prevent rapid urban expansion, urban planners and
decision makers need to regularly evaluate development procedures
using updated urban planning maps.However,many
city planners in developing countries lack access to updated
maps and often rely on old data that are not relevant [1]. One
of the possible solutions could be the use of RS images with
different spatial and spectral resolutions. As the present RS is
so advanced, it is now possible to extract different thematic
information at various scales, to integrate the extracted information
with other historical data sets stored in a GIS and
to conduct sophisticated analyses [1].
