Solid waste generation is increasing rapidly in urban areas of India as well as globally. As land resources for waste disposal are limited in highly populated countries like India, identification of solid waste disposal sites in urban centres is a challenging task, as this involves physical, socio-economic and environmental factors. Dehradun, the capital city of Uttarakhand at present has only one disposal site which is not having good spatial accessibility for all the locations in the city and also it is an environmentally vulnerable site. The present study aims to find suitable sites for decentralized solid waste disposal using geospatial techniques with multi spatio-temporal remote sensing data. A geospatial multicriteria analysis was performed with weighted overlay technique by considering various criteria such as physical, social and demographic aspects of the city for locating the solid waste disposal site(s).
