GIS can be applied to various urban planning problems, such as master planning, area monitoring, regional potential analyses, site selection studies, and the documentation and approval of development plans. It is useful for interpreting and formulating land use policy, modeling likely land use changes, and assessing the impacts of predicted land use changes. GIS is also significant for environmental planning, such as developing natural resource inventories, identifying pollution sources, assessing constraints, and determining suitability for waste treatment techniques. It can also help with wetland applications like regional inventories.
