| Sumario: | The identification of empty areas in the internal stnicture of ciaies is of relevante to the
urban planning process, regardig unproved land use The use of remote sensing techniques
and products in urban studies has previously shown its eíliciency In spite of that, orbital
imagery show certain reshictions in intemal urban studies, owing to their spatial resolution
The aim of this work is to wntribute to the use of orbital únages in internal urban studies
testing an application of a segmentation technique It is based on the method of region
growth, in HRVISPOT panchromattc and rnultispectral images, and of the resulting hybnd
product arising frorn the fusion of those images through the MS transformation, this results
in an ohjective delimitation of empty urban m The selected test area involves part of the
GuamIhos municipality, in the Sao Paulo state of Br&l Aesults were qualitatively anaiyzed
in the wmputer monitor, those wrresponding to the hydrie component were of particular
interest shce they yield spatial and spectral information simultaneously on the empty urban
areas. ailowing for a better discrimination. |
