The remote monitoring of electromagnetic radiation allows to differentiate the behavior of five different wavelengths that are shown as images in their respective visible and non-visible light spectral, these are subjected to a processing in which it is calculated for each pixel using the red band and near infrared the normalized difference vegetation index, with which a multispectral orthophoto mosaic is generated which is later analyzed with the objective of estimate the quantity and quality of vegetation of 15 hectares of different properties in the municipality of Tuta in the department of Boyacá, Colombia, that they possess with a high productive potential and in which the process of information acquisition was carried out before and after proceeding with the implementation of crops with a previous agroecological model, Later, a statistical analysis was carried out using polynomial trend models, and this remote inspection system identified that the behavior of radiation intensities at different wavelengths is associated with variable vegetation densities and, indirectly, with the presence of water stress and the quality of the shrubs and plants.
