The MapBiomas Water \u2013 Peru Initiative (Collection 4) aims to map the dynamics of surface water, glaciers, and snow cover across the entire country for the period 1985\u20132025.<\/p>\n\n\n\n
METHODOLOGY FOR SURFACE WATER MAPPING<\/strong><\/p>\n\n\n\n Unlike MapBiomas Land Cover and Land Use, surface water mapping is produced at a monthly time scale. The following products are available on the platform:<\/p>\n\n\n\n \u2022 Annual Surface Water If you wish to consult the complete MapBiomas Water methodology, the ATBD (Algorithm Theoretical Basis Document) is available at this LINK<\/a><\/p>\n\n\n\n METHODOLOGY FOR GLACIER AND SNOW MAPPING<\/strong><\/p>\n\n\n\n Glacier mapping is produced annually for the period 1985\u20132025 and corresponds to the same information presented in the MapBiomas Land Cover and Land Use maps. Snow cover mapping is also produced annually, covering the period 2000\u20132025.<\/p>\n\n\n\n The following products are available on the platform:<\/p>\n\n\n\n \u2022 Annual Extent (Glacier and Snow Cover) To learn more about the complete glacier mapping methodology, please refer to the ATBD available at this LINK<\/a><\/p>\n\n\n\n
