Since, natural disasters are inevitable worldwide phenomenon resulting tremendous loss of property along with human casualties, the paper focuses on application of GNSS technology coupled with web APIs and remote sensing for disaster management (use case as flood) for disaster preparedness, relief, rescue and recovery plan. With the wise use of GNSS, we can anticipate the loss due to natural disasters mitigated significantly, if not annihilated.
The basic concept is to track flood level rise in rivers and streams to provide real time alerts to all the stakeholders and then its management and plan aftermath. Flood level rise is measured using sensor in river which sends message to primary or base warning station. The base station is equipped with devices receiving and transferring those messages to next level flood warning station along with stakeholders in the form of SMS and other web communication methods. The telecommunication messages with geo-spatial information are sent to web system for thorough analysis which can be disseminated in the form of thematic maps either online or offline via web servers. These maps can be used by governing agencies and humanitarian organizations for rescue planning and relief disbursement. Finally, in the next phase, satellite images with GNSS collected data are used for quantification of damage estimation which can be used for sustainable recovery planning and rehabilitation.
Thus, GNSS technology when wisely coupled with web APIs and ICTs, can effectively play vital role in providing early warnings and emergency response. Search and rescue planning can be highly efficient by the use of social media and mobile networks while remote sensing images can aid in quantifying damages.
