Abstract
This paper proposes a method of valuing the stock
of residential buildings in Spain as the first step in assessing
possible damage caused to them by natural hazards. For
the purposes of the study we had access to the SIOSE (the
Spanish Land Use and Cover Information System), a highresolution
land-use model, as well as to a report on the financial
valuations of this type of building throughout Spain. Using
dasymetric disaggregation processes and GIS techniques
we developed a geolocalized method of obtaining this information,
which was the exposure variable in the general risk
assessment formula. Then, with the application over a hazard
map, the risk value can be easily obtained. An example
of its application is given in a case study that assesses the
risk of a landslide in the entire 23 200 km2 of the Valencia
Autonomous Community (NUT2), the results of which are
analysed by municipal areas (LAU2) for the years 2005 and
2009.
