Land use planning is an important tool in adequate spatial distribution of land among various activities and functions at local, regional and national planning. Recent developments in information technology such as GIS and PPS (planning support system) has significantly improved the analytical abilities of land use planners in developing land use plan based on more accurate and detailed data as well as use of more sophisticated techniques. What if? Is a PPS developed especially for land use planning? What if? uses GIS technology and land use planning models to help planners create land suitability reports, land demand analysis, land allocation, and land use protection based on pre selected assumptions and scenarios.
