Evaluation of land cover data product accuracy in urban agglomeration on the northern slope of Tianshan Mountains in Xinjiang
摘要
Abstract
Land cover data products,including CLCD30(30 m resolution),GlobeLand30(30 m,referred to as Globe30),GLC_FCS30(30 m),FROM-GLC10(10 m),Esri_Land_Cover_2020(10 m,referred to as Esri10),and ESAWorldCover2020(10 m,referred to as ESA10),provide essential surface cover information for various earth system science applications globally.However,their accuracy and suitability for specific local areas remain uncertain.This study evaluates the accuracy and errors of these six land cover products in the northern slope of the Tianshan Mountains in Xinjiang,China,based on Sentinel-2 imagery,using sample accuracy assessment and category confusion evaluation.Furthermore,the causes of errors and the applicability of different products were analyzed.The results indicate that:(1)Among the six data product sets,except for Esri10,the composition and ar-ea percentages of land cover types are relatively consistent across the other five products.(2)The overall accura-cies of these products are:GLC_FCS30(0.8080),Globe30(0.8147),CLCD30(0.7880),FROM-GLC10(0.8531),ESA10(0.8047),and Esri10(0.4725).(3)Regarding product applicability,GLC_FCS30 is effective for analyzing cropland and bareland;CLCD30 is optimal for forest and bareland;FROM-GLC10 excels in represent-ing grassland,water bodies,snow/ice,and built-up areas;ESA10 is suitable for cropland and grassland;Esri10 performs well in forest,snow/ice,and built-up areas;and Globe30 maintains overall stability in accuracy across all categories.(4)Major category confusion occurs between cropland,forest,grassland,and other categories,es-pecially in areas with complex land cover,such as urban fringes.关键词
