Noise impact assessment using corine land cover methodology: A case study in Funza, Colombia

Abstract

The spatial distribution of sound pressure levels was analyzed in Funza, Colombia. This survey allowed the identification of several noise sources linked to human activities in the area. To accomplish this, 52 sampling points were distributed all over Funza; measurements were done during day and night time according to environmental regulations. With the sound pressure levels of each point an environmental noise map was generated for both, day and night time. This map was generated with the software ArcGIS 10.5 and compared with regulations. Compliance of environmental noise in Funza was evaluated with a land use cover map; this map was made applying Corine Land Cover methodology adapted to Colombia. Results obtained showed that, during day time 18% of the Funza area complied, while at night time is only 9.6%. The low percentage of compliance is related to high traffic in the main roads that flows to Bogota; in addition to El Dorado airport landing route located South West of Funza.
