regional unmixed mean les moyennes spécifiques à chaque région Explanation: This procedure computes databases with the mean values of any IMG-variable for a set of administrative regions. """""""""""""Optionally, the means are also “unmixed”, i.e. specific for each crop or land cover class""""""""""""". In this way, the image data become compatible with the other agro-statistical information (official areas/yields, CGMS-outputs,…) in a spatial and thematic sense. The agro-statistical region (or district) replaces the pixel as spatial unit, and the crop/class becomes the thematic unit. The procedure also involves an important data reduction. The format of the files containing the RUM-values is described in the section Formats. |

regional unmixed mean valor promedio de la variable NDVI en una cierta región Explanation: Regional Unmixed Means (RUMs) for a variable (here, NDVI / Índice de vegetación de diferencia normalizada) represent the average value of the variable over a specific geographical entity. If only the contribution of the pixels for a specific land cover or crop cover type within the entity are averaged, then this mean is said to be "unmixed". |
