MultiSpec program

CEU eTD Collection
MultiSpec program is a processing system for interactively analyzing Earth observational multispectral image data such as that produced by the Landsat series of Earth satellites and hyperspectral image data from current and future airborne and spaceborne systems such as AVIRIS. In particular, Landsat satellite images have been used for the present research.
This software has been selected because it is a very valuable tool and is a much faster method than using the aerial photo methods. It is quite accurate and it makes possible to achieve higher levels of accuracy with better resolution.

4. Limitations of the Research

There were several factors that hampered the present research. One of them was the failed research trip to Uzbekistan, which was due to two main causes. On the one hand, the complicated political situation in the Central Asian region affected the organization of the planned research trip. On the other hand, lack of possibility to organize a number of meetings

with experts in water management and other water-related issues also influenced the preparation for the research trip.

4. AYDAR-ARNASAY LAKES SYSTEM: LOOKING INTO

THE PAST
The following chapter analyzes historical features of the Aydar-Arnasay lakes system (AALS) development based on the documentary research, i.e. literature found in the archives, valuable information received during the unstructured interviews in Moscow, and use of different satellite images obtained from GIS data mining. The main methods for the data analysis, described in the research methodology chapter, have been applied for working on this chapter.
The present chapter consists of two main sections. The first section focuses on analysis of the main historical stages of the Aydar-Arnasay lakes formation. Having considered all relevant archive materials, the AALS historical stages have been combined and described by the author. Moreover, in order to show the lakes’ historical development more demonstrably, a set of maps using GIS methods has been created by the author.
The second section examines the change dynamics of the AALS water-surface area and volume in 1969-2009. This section contains the description of the practical exercise accomplished by the author. The main idea of this exercise is to calculate the AALS water- surface area and volume during 1969-2009 using GIS methods and examine change dynamics during these years. This exercise has provided valuable data about water-surface area and volume of these lakes in the period 1969-2009 which allow conducting extensive analysis of change dynamics of these characteristics.
