ABOUT LAB
Vocation of LTG - Topography and Geodesy Laboratory
Develops educational laboratory function, using modern equipment to support undergraduate practical classes and graduate.
It also develops research projects with an emphasis on calibration topographic and geodetic instruments, establishing key networks (planimetric and altimetry), digital cartography and geodetic positioning satellites.
It stands out as a world-class contribution to establish a instrument calibration network in Olympic streak USP, the establishment of geodetic precision satellite network of the State of São Paulo, the construction of the gravimetric map (geoid letter) of Brazil, and South America, the implementation of continuous monitoring stations in collaboration with other institutions.

Our philosophy
The Laboratory has developed a didactic function, using modern field equipment, teaching topography classes at undergraduate level for students of Civil Engineering, Mining Engineering, Geology and Architecture. It also has distance meters and GPS receivers for graduate classes in Geodesy.
Develops emphasis on research work in calibration and measurement instruments (distance meters, theodolites and levels), in the establishment and / or study of core networks (planimetric and altimetry), digital cartography (digital terrain modeling and update maps by remote sensing ) and positioning satellite (GPS).
The LTG has encouraged research through internships for graduate students, undergraduate students and monitors students.
It stands out as a national and international level of contribution the establishment of a MED calibration network - electronic meters away on the Olympic streak of USP University City; the implementation of the São Paulo State GPS Network; the making of the geoid map of Brazil, Uruguay and South America and participation in several international geodetic campaigns.
Our history
Teaching and research at the Polytechnic School of the University of São Paulo in Transport Engineering area are as old as the school itself (1894). Since the beginning had a civil engineering course with a strong emphasis on the Transport of disciplines, among whom were: Topography, Shooting Roads, bridges and sidewalks, Inland waterways, sea ports and Railways.
The very founder of the Polytechnic School, Antonio Francisco de Paula Souza, developed the topography and introduced new processes in Brazil as photogrammetry and tacheometry, writing the first book on this subject in the country. Over the years, the School has contributed remarkably to the development of national technology in transport.
Currently the course of Civil Engineering is divided into four departments, one of the Transportation Engineering - PTR, in turn divided into three sub-areas. Among these, is the spatial information which brings together three laboratories; one of them, the Topography and Geodesy Laboratory - LTG.
