The Remote sensing is the analysis of electromagnetic radiation across different wavelengths and its interaction with targets on Earth's surface. Remote sensing techniques are becoming increasingly important in understanding global land and resource uses. As a tool for improving the management of land including the production of food, monitoring deforestation and managing environmental impacts of land use change (LUC). Mapping and monitoring vegetation over a long period of time also allows area to estimates the land use and land cover change analysis, providing an important tool for environmental impact assessment. For monitoring vegetation dynamics there are three regions of the electromagnetic spectrum in which different factors control the spectral response to radiation. The increasing use of biomass for bioenergy is related to recent dynamics in land cover, with possible impacts on environment and climate. The radiation generated after this interaction with the target brings information that differentiates it from other targets allowing its identification and study.
