Application of Trend Surface Analysis to estimating Carbon Monoxide (CO) in urban areas
Abstract
Application of geomathematical methods to the analysis of distribution patterns of spatial variables has been common in cartographic studies. Among those methods, one of the simplest and most efficient is the “trend surface analysis”. With the application of that method two patterns of space distribution can be obtained: one of regional nature, represented by the polynomial surface adjusted to the data points, and the other with the local floatations, identifying areas with anomalous values represented by the residues. As an example of application of that methodology, carbon monoxide (CO) was used as a variable, sampled in the urban area of Rio Claro city/SP. That pollutant, when present, influences the environmental conditions in urban areas, and its space distribution, in a significant way as verified in this work. It is, therefore of fundamental importance to guide planning studies in urban health.
