Present study was thus focused on presenting a comparative case study for detecting the change analysis of two watersheds in Islamabad, namely Rawal and Simly Watershed using satellite data obtained from Landsat 5 and SPOT 5 for the years 1992 and 2012 respectively. Land cover and land use change was detected by applying Supervised classification-maximum likelihood algorithm in ERDAS IMAGINE and five land classes were delineated viz., Agriculture, Bare soil\/Rocks, Settlements, Vegetation and Water. Furthermore, land cover\/land use and overlay maps for both Watersheds were created in ArcGIS. Achieved overall classification accuracies were 95.32% and 95.13%, while Kappa statistics were 0.9237 and 0.9070 for the final land cover\/use maps of 1992 and 2012 respectively.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659759567\"\u003e\u003ch3\u003eA Comparative Case Study of Rawal and Simly Watershed, Pakistan\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659759567","offer_id":39434711367773,"sku":"9783659759567","price":54.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d2bd640e-489d-4af4-b067-fac98293ad1e.jpg?v=1776231729","url":"https:\/\/shop.autorenwelt.de\/products\/change-analysis-of-watersheds-using-remote-sensing-gis-applications-a-comparative-case-study-of-rawal-and-simly-watershed-pakistan-von-amna-butt","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
