Key components in urban and regional planning are demand assessment in water supply and sewerage networks, engineering network design, engineering network condition monitoring and accident prevention , urban planning and design.
    Every day, planners use Geographic Information System technology to research, develop, implement, and track their plans. they do. GIS provides planners, surveyors and engineers with the tools they need to design and map their neighborhoods and cities. Planners have the technical expertise, political acumen, and financial understanding to translate a vision for tomorrow into a strategic action plan for today, and use GIS to facilitate the decision-making process.
    Desertification is land degradation as a result of climate change or human activity. GIS can provide information on degraded land that can be managed by government agencies or communities themselves. GIS plays an important role in reducing desertification, local governments are now heavily dependent on GIS to reduce desertification. With location-based GIS analysis, we can find out where and which area is suitable for planting new vegetation and which area is suitable for laying a pipeline.
   
 GIS technology is used to analyze urban growth and its expansion direction and to find suitable locations for future urban development . Certain factors must be taken into account to determine suitable areas for urban development: the land must have adequate accessibility, the land must be more or less flat, the land must be vacant or currently of low use value, and there must be good amenities. GIS has many uses and advantages in the field of object management. GIS can be used by facility managers for space management, visualization and planning. It can be used from deciding where to build facilities to planning the space. Also, GIS facilitates better planning and analysis.
