GIS BASED LAND INFORMATION SYSTEM FOR MANDAL SOUM, SELENGE AIMAG OF MONGOLIA

摘要

It is important to learn about and use Geographic Information Systems and Remote Sensing data and software for our profession nowadays. Modern technologies like geo-data processing and earth observation data processing and analysis are needed for Mongolian young researchers and students. This research work is dedicated to create a land information system over agricultural areas of Selenge Aimag (state), Mandal Soum (province) of Mongolia. One task of the work is to establish a land information database which is based on an Open Source Geographic Information System. Work is starting with acquisition of existing geodata and information, qualification, maintenance, utilization and transferring of data from one soum of Mongolia. Furthermore, the principles used for this soum will serve as a pilot and can be applied to other soums in Selenge Aimag and other agricultural areas of Mongolia. This research work will be helpful to establish a structured cadastral database, multi user access to the database, avoid data redundancy of different organization and follow international standards for geographic information. The "Land Management and Fiscal Cadastre" (LMFC) project's aim is to develop a land valuation methodology based on a land information system for selected project areas. The project established already a cadastral database for Darkhan-Uul Aimag settlement area. Continuing work will be done for agricultural and rural area of Selenge, Mandal area. Promoting education and training at fundamental and professional level for land managers and students are vital for the establishment of land information systems in developing countries. The establishment of a land information system for Selenge Aimag will contribute to the National Land Information System of Mongolia. The project demonstrates that Land Information Systems can be created using Open Source GIS software as e.g. QuantumGIS, gvSIG, uDig and the Open Source database management system PostgreSQL /PostGIS. Systems which are based on Open Source GIS software are new for many professionals in Mongolia and of special importance for developing countries due to their cost efficiency. To connect this work to the practice, students of GIS-RS laboratory at Plant Science Agricultural Training Research Institute (PSARTI), which belongs to the State University of Agriculture of Mongolia, are taught as well as staff from other Government institutions. PSARTI works with several international institutes and projects in different fields. The results of the project activities are shared and advise about the use of Open Source GIS software for different education, research and professional level is given, using the establishment of a land information system with complete land coverage and multi cadastral functions in Mongolia. Promoting the use of Open Source GIS software, enhancing data quality and knowledge exchange are the main aims to be followed further. It is important to experiment and use the project results on a national level and to provide education on Geographic Information Science and Systems to researchers and land managers, students in the land management and administration sector. The results will promote good governance and provide fact based information to decision makers and government.
