PLASCO BUILDING CRISIS MANAGEMENT FROM QUALITY INDICATORS PERSPECTIVE

Iran has always been exposed to numerous disasters and crises, which has caused many losses. An example of such crises was the fire and the collapse of the PLASCO building (Fig 1), one of the commercial and shopping centers in Tehran, which occurred in 2016 and mainly caused irreparable effects on some people life. At that time, various groups such as fire stations, crisis management, police, and rescue teams were dispatched to the scene. In general, the most important necessity for these groups to restrain the disaster is awareness of the current situation in which spatial data has ability to supply their needs. Meanwhile, spatial data has been voluntarily created by members of general public, could be a precious alternative for the reference data due to offering substantial characteristics such as: local knowledge, timely creation or free use of data. On the other hand, the qualitative specification of data has a key role when working with all kinds of data, although volunteered geographic information suffers from the lack of quality awareness which has led to hesitate about usage of this type of data in this particular subject. Therefore, we aim to set out a workflow which could support the decision whether volunteered geographic Information or VGI data could be adequate for disaster management or they could meet the active group s expectations or not.
