KNOW THE STEPS OF THE MAPBIOMAS COLOMBIA METHODOLOGY

Here you will find the main characteristics, the way to organize the methodological flow and a general description of the MapBiomas Colombia methodology used to generate land cover and use maps and land use transition/change maps.

GENERAL CHARACTERISTICS

Todos los mapas anuales de cobertura y uso del suelo de MapBiomas Colombia fueron producidos a partir de la clasificación píxel a píxel de imágenes del satélite Landsat. Todo el proceso es realizado con algoritmos de machine learning a través de la plataforma Google Earth Engine, la cual ofrece inmensas capacidades de procesamiento en la nube. Para facilitar la parametrización de los algoritmos y la organización de todas las etapas de procesamiento se utilizan un total de 47 cartas y 48 path y rows. Cada carta tiene dimensiones de 1 x 1,5 grados (lat/long).

HOW WE ARE ORGANIZED

The methodological details and national categorization are organized by region (in the context of MapBiomas it corresponds to an approach to the regions of the country), and also through transversal themes that are detailed by specific methods from the perspective and technical capacity of the earth science specialists who are part of the project. You can find more details in the “About us” section.
