The aim of this study was to estimate glacier cover using optical remote sensing data Turgen Mountain strictly protected area in Uvs province, Mongolia. Two widely used snow indices were compared for this study: Normalized Difference Snow Index (NDSI) and Snow Grain Size Index (SGI). Both indices were trained to estimate glacier cover derived from Landsat Thematic Mapper (TM), and Observed Land Imagery (OLI) multi-temporal satellite imagery. The result shows that NDSI was successful delineated glacier cover from other land covers. However, NDSI was sensitive to water bodies found on the lower ground within the study area. NDSI and SGI created comparable results; the SGI was capable of mapping glacier snow cover from other related land covers with more accuracy.
