| Palavras-Chave | urban groth evolution models interpolated time image |
| Resumo | Growth models of urban clusters are developed to understand the mechanisms of city evolution.Natural,social and economical constraints must be considered in studies of the spatial dynamics of the Latin American cities. However,to describe the urban evolution, methods to generate and handle growth vectors are needed.Great part of this kind of study ocuses on qualitative analyses,where trend vectors are manually defined.This research presents an algorithm for the estimation of speed and acceleration of the urban growth.The proposed approach produces results on raster databases,spatially modelled pixel by pixel.This data structure allows integration with other raster base,such as satellite and DEM-derived relief data (slope,altimetry,for example)and others.This method uses the temporal series of the city limits,extracted from satellite imagery.These limits are stored in the vector format labelled with time as z-value, expressed in years,months or days.The interpolation,through kriging techniques,produces a timely based image of the urban growth.Since speed is a relation between ....as and ....at (where ....as is space differential and ...at the time differential),a growth speed image can be calculated using the expression v=resolution/z,or the inverse of the time image gradient,automatically obtained with the slope angle function.Once acceleration is the relation ...av/...at, the same approach can be applied for its calculation.Convolution filtering with 3x3 pixels moving windows on the growth speed image may indicate the higher gradient among the eight windowed neighbours,so as to generate a ...av image,which can be divided by the ...at image to produce the acceleration image.Aspect function may be used to generate the directions of the calculated vectors.The developed program automatically executes all these operations to calculate speed and acceleration from the interpolated time image.Tests under varied hypothetical conditions showed the program to perform very well,with promising potentials or the analysis of urban growth,crop expansion, deforestation,gully erosion,as well as any other growth phenomena of different temporal and spatial scales. |
