Small Hydro, companies | corporations and | or contractors must obtain Environmental Licensing (Permitting) (EL). The EL procedure is established "legally"in a bureaucratic routine that requires a series of documents, including maps. However, the specification and characterization of cartographic documentation for this purpose lies below the real need for analysis of the human intervention that will occur, especially from the environmental point of view. Aiming to better recognize the territory to be impacted and suit the environmental licensing procedures in accordance with the new national standards (Law 10.267, Guideline 511 of 2009 of the Ministry of Cities), among others - research proposes the use of information form the Multipurpose Territorial Cadastre - MTC. Starting from the consideration of the relevance of the MTC in the current context of environmental permits, the potential in the use of the MTC in the licensing process were listed. In this sense, the goals were tied to political and institutional constraints, the availability of information and interests inherent in the decision making process of environmental licensing. In this regard, some limitations regarding the mandatory use of information from the multipurpose territorial register were highlighted, which stem from the current national situation. The method was based on descriptive exploratory study that proposed the introduction of the MTC as a compulsory tool for improving the environmental licensing of SH. From the case study of SH Bocaiuva the proposition has been consolidated and made research investigation consistent with the demand of environmental agencies, since the use of the MTC in the environmental licensing process for the profile of SH Bocaiuva, replicates in many other similar situations nationwide. As a result, adaptations and extensions in the administrative, physical, biotic and anthropic parameters were proposed, considering the land plot and thematic register as a focus on graphical representation, and therefore being a reference to the environmental licensing process.
