Abstract. The main focus of this study is to ascertain the relationship between urban and mining growth of Makrana City using remote sensing and spatial metrics. This relationship was assessed on the basis of information extracted by temporal remote sensing data from 1972-2012. To establish the relationship, the satellite data are classified into built up and mining area. Over the four decades there has been vast increase in built up of the city, by 1345 hectare, along with the significant increase of the mining area by 148 hectare during the same period. There is huge increase in consumption rate and absorption coefficient; especially high absorption coefficient found during 2003-2012 for mining and built up indicated enormous increase in growth of city. The FRAGSTATS tool is used to evaluate the urban growth with change in mining area. The results showed that built up area and mining area changed significantly over time. The analysis also exhibits a spread out pattern of built up area development with huge growth in city periphery. Most of new built areas are developed near and along the mining area. The remote sensing data integrated with spatial metric approach provides important information that can be used to understand the mining growth impact on urban development.
