Biophysical Parameters Map


A map of biophysical parameters is a product that contains information about the physical and chemical properties of certain phenomena on the Earth's physical surface.

Areas, acquisition epochs and biophysical parameters that were created are:

1. SPOT 5 satellite imagery from 2011, 10 m GSD, covering the territory of the Republic of Serbia

  • aux_alt (altitude) – altitude value obtained from the digital terrain model;
  • aux_slp (slope) – calculated slope values;
  • aux_tril (illumination) – calculated values of the amount of illumination;
  • blcv (brown cover fraction) – share of brown vegetation within one pixel;
  • chl (leaf chlorophyll content) – mean value of chlorophyll content in leaves per area unit;
  • csh (canopy shadow factor) - a parameter that characterizes the irregular shape (uneven spread - roughness) of the canopy on the vegetation cover suitable for separating shadows in relation to the rest of the image content;
  • dcl (cloud reflectance) – value of reflection of sunlight from clouds;
  • glcv (green cover fraction) – share of green vegetation within one pixel;
  • sb (soil brightness) – value of sunlight reflection from bare soil;
  • scv (soil fraction) – part of the soil that is not covered by vegetation (1 - (glcv+ blcv));
  • visi (distance of visibility) – horizontal visibility. The value of this parameter depends on the coefficient of reflection of sunlight from particles in the air (aerosol);
  • wat (leaf water content) – mean value of water content in leaves per area unit;
  • xsf (vegetation brown ratio) – ratio of the share of brown vegetation in relation to the total vegetation;
  • mwh (water height) – mean value of water height;
  • wcv (water fraction) – share of water cover per pixel.

2. SPOT 6 satellite imagery from 2013, 6 m GSD, covering most of the territory of AP Vojvodina and the territory east and south of Belgrade

  • glcv (green cover fraction) – share of green vegetation within one pixel;
  • blcv (brown cover fraction) – share of brown vegetation within one pixel;
  • csh (canopy shadow factor) - a parameter that characterizes the irregular shape (uneven spread - roughness) of the canopy on the vegetation cover suitable for separating shadows in relation to the rest of the image content;
  • wcv (water fraction) – share of water cover per pixel.
