title A METHOD FOR REAL TIME SPATIAL ANALYSIS OF SOUND VIA MODELING IN A CAD ENVIRONMENT, BASED ON ACOUSTICAL MEASUREMENTS
source 14th European Colloquium on Theoretical and Quantitative Geography,September 9-13, 2005, Tomar, Portugal
summary Typical modeling systems for spatial analysis employ data that represent the visual part of a landscape (e.g. relief and morphology), combined with other data about specific attributes (depending on the aims of an application). Thus, in a modeling environment, each place is described by a variety of properties that are not always visible. More of those “hidden” properties require special sensors and/or instruments to be captured and sometimes make their presence evident through human senses, such is sound. The present study takes advantage of wide spread technologies (such as GPS, VHF telecommunications and field sensors) and methodologies that are commonly used in telegeoprocessing – telegeomonitoring in order to simulate an existing acoustic environment. The aim is to acquire real time data about the sound (referenced to a particular area) and manipulate them in a CAD environment with purpose to visualize the sound influence in a specific landscape. Specifically it is proposed a method that transfers spatial data (collected from the field), directly into a modeling system (in the office, or in situ). In sequence the data is processed adequately to feed the modeling system that describes the current sound intensity of a place.
