Abstract Identification of suitable site for urban development in hilly areas is one of the critical issues of planning. Site suitability analysis has become inevitable for delineating appropriate site for various developmental initiatives, especially in the undulating terrain of the hills. The study illustrates the use of geographic information system (GIS) and multicriteria evaluation (MCE) technique for selection of suitable sites for urban development in Mussoorie municipal area, Dehradun district, Uttarakhand. For this purpose Toposheet and IKONOS satellite data were used to generate various thematic layers using ArcGIS software. Criteria using five parameters, i.e. slope, road proximity, land use/land cover, land values and geological formation were used for site suitability analysis following land evaluation. The generated thematic maps of these criteria were standardized using pairwise comparison matrix known as analytical hierarchy process (AHP). A weight for each criterion was

Introduction Site suitability analysis helps in identifying suitable sites that meet specific criteria or restrictions. This analysis greatly reduces the time as well as effort that have to be put in otherwise in manually searching the records, processing data and undertaking field surveys. Acquiring new site for urban development or improvement is becoming increasingly challenging, particularly in a growing real estate market and with stringent environmental standards or regulations. The results of the site suitability analysis produce a detailed display of the most-suitable areas for consideration of placement of a certain facility, while filtering out unusable or less desirable sites. Certain aspects are more important than others in determining the best location for each facility. The selection of suitable sites for specific uses must be based upon a set of criteria depending on local norms. A scoring and weighting system can be applied to the various aspects of suitability to assess the overall suitability for a specific urban use.
