Temporal and spatial changes in a mountainous area of central Italy
Authors:Patrizia Peroni  Fernando Ferri  Gian Carlo Avena
Abstract:Abstract. In this paper we present an application of aerial remote sensing to the analysis of spatial information in a mountainous area of central Italy by applying texture measures and landscape indices. Land cover data acquired in different time periods are used to calculate measures of landscape pattern and structure at pixel level (tone and texture variables) and patch‐level (landscape indices). Images of the patches from the 1950s, 1980s and 1990s have been derived from the tone‐texture classification of scanned black‐and‐white photographs. Multitemporal analysis of landscape indices has been performed to detect changes of landscape elements and related effects on vegetation dynamics due to the reduction of human impact.
Keywords:Aerial photograph  Autocorrelation function  Landscape index  Remote sensing  Texture analysis
