Currently, there exist many differences between the significant indicators related to issues of water and environmental sanitation in Vietnam. Ministries, departments and organizations involved often use other sources and conflict in the efforts to solve the same problem in rural areas.

In order to solve this problem, UNICEF, CERWASS and other organizations including The National Target Programs for Rural Water Supply and Sanitation, General Department of Statistics, Ministry of Health, World Bank, DANIDA, AusAID, Luxembourg Government and VidaGIS Company with the cooperative development of a comprehensive system for monitoring water supply and sanitation in rural areas. This system aims to resolve all existing issues which are overlapped and allowed authorities at all levels setting up the plan on the basis of the standard data and accurate comparisons.

Natural water is considered to be invaluable resources for humans. For the developed countries, water resources are a very important role and are set on top in the exploitation in using and managing with large scale. Conversely, for the slow development country or developing countries, the role of water has never been clear awareness, but it is frequently using waste and it has dynamics to conserve and use precious minerals resources effectively.

Therefore, some international cooperation projects has coordinated with these countries to implement and deploy awareness about the role of the water, the supported exploitation, consumption and general management of water natural resources with the reasonable, sustainable and effective ways.

Because GIS is designed as a general system for managing spatial data, it has many applications in the urban development and natural environment such as urban planning, human resources management, agriculture, public benefit operating, route, demographics, maps, sea supervision, fire fighting and diseases. In most areas, the GIS act as a tool for support decision making in planning activities.

Environment

According to the most GIS experience experts, there are many applications developed in organizations concerned with the environment. With the most simple, users can use GIS to evaluate environment such as location and attributes of forest trees. GIS applications with the more complex are to use analysis capabilities of GIS so that the process modeling of land erosion, the spread of pollution in the air or water, or the reaction of a river watershed under the effect of a deluge. If the data collection is connected with zone objects and applications using the complex analysis functions, the data model under the raster image will be prevailing.
