Abstract

During the summer period, fire hazards represent an especially real threat not only for vegetation and animals, but also for material resources and human lives. In the Republic of Croatia, the most affected areas are those in the coastal region, which are characterised by a very dry environment and strong winds that are conducive to the rapid spread of wildfire. Although the prevention of wildfire is an utmost imperative, many countries are still missing a good and reliable fire management system for both fire monitoring and prevention and post-disaster management. The aim of this paper is to show the utilisation of open source GIS, web-based technologies, and open data in the case of natural disasters, and to define the concept of advanced national system of compensation determination. Such a system could be utilised to identify land parcels for which compensations for damage and losses after fire devastation have to be determined and could be used by compensation agencies, insurance companies, or state administration. The island of Hvar, which has suffered from fire hazards, was used as a case study for a quick and relevant calculation of the compensation based on land administration data. Sentinel satellite images and official digital orthophoto maps (DOMs) of the affected area before and after the fire devastation were obtained and analysed together with the data on cadastral parcels and land owners. Research was conducted by using both sets of imagery data, showing that Sentinel satellite images are more than adequate for fulfilling the task of the determination of hazard compensation.

Highlights

The concept of disaster management represents a special area of management
It is based on the open data concepts, which implies that the available data can be freely used, reused, and shared by anyone without restriction, with the obligation of specifying the author’s name and further sharing of the data under equal conditions [20]
We decided to use the State Geodetic Administration’s (SGA) most recent official digital orthophoto map (DOM) after we discovered, via the DEMLAS web interface, the information about its availability through the SGA Web Map Services (WMS) service

Summary

Introduction

The concept of disaster management represents a special area of management It is an essential part of functioning civil institutions as risk and crisis management are an essential part of daily human life. The recent development of geodetic surveying sensors and methods including remote sensing, together with the development of information technologies and data distribution capabilities, allows for the improvement of official spatial data registers. These include the use of existing land administration infrastructure (LAI) [4] and their improvements [5], in order to enable the risk management of crisis situations (i.e., managing the risk from natural disasters such as earthquakes, wildfires, floods, droughts, and landslides). In the context of this research, the preparation phase of disaster management was approached with a GIS (geographic information system) based MCDA (multi-criteria decision analysis) (G-MCDA) vision [6]
