The following study has as objective the Use of Geotechnology to the Territorial Ordering of Porto Nacional City, in Tocantins State Brazil. The territorial organization of Porto Nacional is known as the North Goiano Golden Cycle, with entrances and expeditions from the South part of Brazil to the North part. The Pará and Maranhão fluvial commerce, the Tocantins River and the Boi Curraleiro Montante, entering from East to West through the western part of Goiás, were historic marks used to orient this investigation. Moreover, with the objective to understand the Tocantins State creation, since the 1988 Brazilian Main Citizens‟ Law and the reduction of Porto Nacional City area, that is given to the capital of the new state, the river becomes a lake with the UHE building, the City wins the rails of the train and the people that used to live by the riverside were moved to another place. We established, as the general objectives thesis to analyze the evolution of the territorial ordering of Porto Nacional City, through the use of Geotechnologies. Thus, we have confirmed the hypothesis that: Geotechnology is an important tool to Government, to use in the Territorial Ordering Planning by public employee that work on this area. The methodology used to orient this piece of research started from careful methods and techniques literature review, the application of physic-territorial analysis and the use of Geotechnology. This work basis is centered on data from the Federal, the State and the City management organization. During the study it was done a temporal analysis in each five years from 1980 to 2013. It was done using the images from the sensor Multispectral Scanner Subsystem Landsat 2 and from the sensor Thematic Mapper Landsat 5 and 8, and from maps of previous classification and topographic letters, facilitating thus the soil use and occupation characteristics class analysis. During the laboratory work it was done the images classification. The SPRING Software (versions 5.0.5 and 5.1.8) from INPE was the chosen tool because through the use of this it was possible to build a data bank, as well as the elaboration of diverse map products used during the study. The research showed, among other factors, that a integrated system utilization that is able to provide information to help during the decision making and considers social data from urban and countryside areas in the physic-spacial and economic aspects is important to contribute to the improvement of all citizens‟ life quality.
