WATER SURFACE MAPPING: METHOD SUMMARY<\/strong><\/p>\n\n\n\n

Aqu\u00ed presentamos una s\u00edntesis del m\u00e9todo desarrollado y aplicado por MapBiomas Agua. Para mayor informaci\u00f3n de los detalles metodol\u00f3gicos entre al ATBD (Documento Base de la Teor\u00eda del Algoritmo) en este LINK<\/a>.<\/strong><\/p>\n\n\n\n

Presentation<\/strong><\/p>\n\n\n\n

El objetivo principal de MapBiomas Agua es  mapear la din\u00e1mica del agua superficial en todo el territorio de los pa\u00edses amaz\u00f3nicos (Panamazon\u00eda), de forma mensual y anual desde 1996 al 2023. El conjunto de datos est\u00e1n disponibles p\u00fablicamente en una plataforma web para mejorar la gesti\u00f3n y el uso de los recursos h\u00eddricos en toda la Panamazon\u00eda. <\/p>\n\n\n\n

El mapeo de superficie de agua en los pa\u00edses amaz\u00f3nicos us\u00f3 todas las escenas del sat\u00e9lite Landsat con una cobertura de nubes  menor o igual al 70%  y una resoluci\u00f3n espacial de 30 metros. El mapeo fue conducido a una escala de sub-p\u00edxel (SWSC), con An\u00e1lisis de Mixtura Espectral (SMA – por sus siglas en ingl\u00e9s) y reglas de clasificaci\u00f3n emp\u00edricas basadas en una l\u00f3gica fuzzy.  El mapeo comprendi\u00f3 el periodo de 1996 a 2023, en la escala mensual, con un total de 396.000 escenas Landsat procesadas y analizadas en la plataforma Google Earth Engine. <\/p>\n\n\n\n

Organization and database <\/strong><\/p>\n\n\n\n

The overall coordination of MapBiomas Water is led by Imazon and RAISG, while technical and operational coordination is directed by Geokarten. The reconstruction of the monthly historical series of surface water was carried out by specialists from all biomes of the Amazonian countries, under the leadership of the following institutions: Fundaci\u00f3n Amigos de la Naturaleza -FAN- (Bolivia), Fundaci\u00f3n Gaia Amazonas -FGA- (Colombia), EcoCiencia (Ecuador), Instituto del Bien Com\u00fan -IBC- (Per\u00fa), Provita y Wataniba (Venezuela), Alliance of Bioversity International y CIAT (Guianas y Suriname). The surface water mapping algorithm was developed by Imazon and adapted by MapBiomas Water in this initial phase of work. <\/p>\n\n\n\n

The development of the MapBiomas Water control panel (dashboard) was conducted by Geodatin and includes significant contributions from the MapBiomas Water working group and platform users in the design thinking process. <\/p>\n\n\n\n

Three types of products were produced by MapBiomas Water: <\/p>\n\n\n\n

    \n
  1. Monthly and annual surface water maps;<\/li>\n\n\n\n
  2. Surface water transition maps between \u201cWater\u201d and \u201cNon-water\u201d classes. This product was processed using the annual surface water database;<\/li>\n\n\n\n
  3. Trend maps (increase and decrease) in surface water. This product was calculated from monthly surface water data in 5 km x 5 km grids.<\/li>\n\n\n\n
  4. Mapas de tipos de cuerpos h\u00eddricos: naturales antr\u00f3picos, hidroel\u00e9ctrica y minero.<\/li>\n<\/ol>\n\n\n\n

    The dashboard (link<\/a>) consists of maps, statistics, and visualization, analysis, and data access tools. It is possible to view the data on an annual and monthly scale, as well as obtain it in different territorial units. Finally, the dashboard also provides a link to access the MapBiomas Water data API. <\/p>\n\n\n\n
