| Summary: | The monitoring and modelling of the evolution of urban areas is increasingly attracting the attention of land managers and
administration. New data, tools and methods are being developed and made available for a better understanding of these dynamic
areas. We study and analyse the concept of landscape fragmentation by means of GIS and remote sensing techniques, particularly
focused on urban areas. Using LULC data obtained from the European Urban Atlas dataset developed by the local component of
Copernicus Land Monitoring Services (scale 1:10,000), the urban fragmentation of the province of Rome is studied at 2006 and
2012. A selection of indices that are able to measure the land cover fragmentation level in the landscape are obtained employing a
tool called <i>IndiFrag</i>, using as input data LULC data in vector format. In order to monitor the urban morphological changes and
growth patterns, a new module with additional multi-temporal metrics has been developed for this purpose. These urban
fragmentation and multi-temporal indices have been applied to the municipalities and districts of Rome, analysed and interpreted to
characterise quantity, spatial distribution and structure of the urban change. This methodology is applicable to different regions,
affording a dynamic quantification of urban spatial patterns and urban sprawl. The results show that urban form monitoring with
multi-temporal data using these techniques highlights urbanization trends, having a great potential to quantify and model geographic
development of metropolitan areas and to analyse its relationship with socioeconomic factors through the time. |
