The uncontrolled growth of Brazilian cities and the intense human activities do not have adequate knowledge of the physical environment conditions in its territory, having as consequences many disasters and economic, social and environmental losses. In this context, the land subdivision, through the physiographic or integrated approaches, emerges as an important instrument for Environmental Assessment. Based on this scenario, the developed research had as main objective the development of a Charter of Physiographic subdivision, at the scale 1: 50,000; with individualization of 8 Basic Units of subdivision (UBC's) internally homogeneous but distinct in its surroundings, related to the Lands physiographies, using photointerpretation techniques in aerial photography and GIS. Such techniques in conjunction with indirect (bibliography) and direct (fieldwork) data allowed the development of a standardized cartographic product, easy handling and interpretation. For the application of the method, it was chosen the Basin of Ribeirão de Araras (SP), where it is located the city of Araras (SP). It was found in the urban area, in fluvial plains, the risk of floods, already in agricultural areas was presented susceptible to erosion and in the northeast basin was checked gully. Therefore, the area should be subject to appropriate territorial planning, in order to avoid or minimize the negative impacts. Under the conditions given, it was concluded that the method used, despite it contains the geological variable as predominant, it is open to other areas of professionals for implementation and not only those who have familiarity with geological issues. It is also expected that this research might support both public institutions, researchers and the private sector regarding physiographic information of the Basin of Ribeirão de Araras (SP)
