Review of works in the field of ecology
based on Remote Sensing and GIS
on the territory of Central Asia and Kazakhstan

The use of GIS technologies allows the integration of large amounts of the cartographic and thematic information into a uniform system, and therefore the creation of the coordinated data structure for analysis of the existing and received information. The projected system enhances the effectiveness of solution of the problems, simplifies and intensifies the process of management decision-making. GIS ensures easy integration and analysis of the remote sensing and field data. The development environments of GIS tools allow the creation of the tailored program modules for the specific targets: data analysis, modeling etc.

GIS structure,as a rule, includes 4obligatory subsystems:

        • The subsystem of the data entry, ensuring the entry and/or processing of three-dimensional data, that were received with the help of the maps, remote sensing data etc.;

        • The subsystem of data storage andsearch, that helps to quickly obtain the data for the analysis, to update and to modify them.

        • The subsystem of the data processing and analysis, which makes possible the estimate of parameters, the solution of the design and analytical problems;

        • The subsystem of the data representation in different forms (maps, tables, images, block maps, digital terrain models etc.)

 

The introduction of the GIS helps to solve the principal management problems due to:

- The enhanced degree of reliability of the information;

- The elimination of the duplicated data;

- The improvement of degree of safety of the information storage and processing;

- The opportunity to represent the information in the different forms (user-friendly);

- The reduction of time spent for the receipt of the required information;

The principaltarget problems are:

- Provision of the computing facilities, in concordance with the information volume, the complexity and the content of the target problems;

- Collection, organization and input of the cartographic and thematic information at the appropriate level;

- Data geoprocessing;

- Three-dimensional inquiries and analyses;

- Geostatistics;

- Three-dimensional data modeling;

- Provision of users with the three-dimensional data, two-dimensional data and the results of their analysis;
