In the present document, methodologies for non-destructive techniques are developed to estimate the index of vegetable biomass of a study area that will undergo an intervention and whose location is near the city of Medell´ın, Colombia. The techniques proposed and compared are: multispectral photogrammetric images, photogrammetric images in the visible spectrum and analysis of SAR products. These techniques were chosen with the possibility of estimating the biomass index of a forest to perform an intervention of the study area, given that an urban construction will be carried out in this space.
