Urban volumetric capacity analysis in Brazil: a Pampulha case study

Since beginning of the implementation of Master Plans the Brazilian urban landscape is being shaped by morphometric parameters. Current regulations on those parameters establish additional coefficients obtained through financial compensation in order to reach two objectives: 1- make the property meet its social function; and, 2 - return to the government profits generated by real estate speculation as they are considered capital gains. This paper analyses the Floor Area Ratio and Coefficient of Utilization or Bulk to investigate the balance between stock and deficit in those parameters, using a 3D source based on Light Detection and Ranging (LIDAR). The goal is to analyse the quality and applicability of urban cadastres and defend 3D cadastres as well as discussing urban landscape morphometric modeling in Brazil. This study is illustrated by a case study of an important modernist neighbourhood, Pampulha in the city of Brlo Horizonte that was projected by Oscar Niemeyer.
