from a spatio-temporal perspective.

Managing urban and periurban areas has become a major factor in this century, since more
than half of the population of the world lives in urban areas. Urban population is growing
rapidly and it is expected to continue increasing the following years (UN, 2014). Analysing the
arrangement of urban areas is related to land management policies, and the tools for
performing it are provided by remote sensing and GIS techniques. On the one hand, remote
sensing and GIS allows for the acquisition of high resolution data in multiple spatial and
temporal scales, used for updating land use land cover (LULC) databases, their management
and analysis. This fact is accompanied by the growing availability of LULC multi-temporal
databases at local scales (Sapena et al., 2015).
In this context, methodologies to quantify the fragmentation of urban areas and their
evolution will be developed, and their relationship with geographic and socioeconomic
variables analysed (Sapena & Ruiz, 2015). Urban growing patterns in different geographical
areas will be characterised by means of the development and implementation of spatiotemporal indices. Subsequently, we will work with hierarchical object-based techniques
applied at different administrative units, the attained results will be related to a set to socioeconomic variables associated to these units, obtained from census and institutional statistics
aiming to test the existing influences of the urban fragmentation changes and growing
patterns. Furthermore, relevant indices for monitoring and modelling urban dynamic studies
will be defined. These tasks are considered essential for managing urban areas.
