The urban forestry is one of the elements that have the primary duty to promote the quality of life in cities. The air quality, thermal, acoustic and psychological comfort are examples of benefits that trees bring to the urban environment. Tree-lined streets and public areas perform other functions such as serving as shelter for wildlife, protection of waterways and connecting corridors between forest fragments inserted into the urban landscape, as well as mitigate emissions of Greenhouse Gases (GHG) such as CO2, acting as natural air filters and sinks of CO2. Thus new remote sensing technologies have emerged to assist in the planning of afforestation in urban environments. The LiDAR system (Light Detection And Ranging), allows the generation of a three-dimensional image of the surface of the layer or forestry. The LiDAR also permits the identification of individual species by analyzing the canopy area and forest stratum through the intersection with multispectral sensors. The objective is to explore the possibility of identifying forest individuals at the species level, from the Américo Renne Giannetti Municipal Park in Belo Horizonte, Minas Gerais, Brazil, through the intersection of LiDAR and hyperspectral images, forming a database that subsidizes the city's urban forestry planning and management of urban green areas. The softwares to be used will be Fusion® version 3.30 in LiDAR data analysis, Quantum GIS® Version 1.8.0 Lisbon and MultiSpec® version 3.3 in the analysis of the data generated by the program Fusion® and hyperspectral images. The intersection form of the images is based on the methodology described by Xiao et al. (2004), Suarez et al. (2005), Tiede et al. (2005) and Ribas and Elmiro (2011). (AU)
