Opportunities for the use of collaborative 3D mapping in post-disaster situations
The rising incidence of disasters, the call for community participation in planning and the widespread diffusion of technology, have recently posed a number of new challenges and opportunities in mapping for disaster response and recovery. Expectations are generally higher than in past times, urban settlements tend to become increasingly complex, and collaborative platforms and apps have started to appear as a bottom-up response to the issue of data accessibility. To promptly assess and monitor post-disaster situations and plan for contexts susceptible to worse damage in the event of aftershocks, many research projects have recently tackled the issue of the quick delivery of cartographies though fit-for-purpose automated mapping procedures. Rapid mapping seems, in most cases, to be bind to the use of satellite imagery. Indubitably, satellite data are an invaluable source of broad scale information along the entire disaster management cycle. However, weather conditions may prevent the images acquisition; damage of the buildings facades cannot be directly perceived; if the elements to map are too small problems of data reliability and accuracy arise; 3D information are limited and update frequency might be insufficient. Given the demand for the continuous enhancement of current mapping products, this paper aims at highlighting novel occasions for the complementary use of photogrammetry as a means to collaboratively enrich remotely sensed information through the processing of street-level imagery collected by people, using smartphones. This may help the planner when, under certain circumstances, spatial data were either unavailable, too poor or excessively delayed.
