Geographic Information System (GIS) assists to govern spatial and non-spatial information in a systematic way. Well organized data and information assists in preferred territorial planning and decision-making process. In GIS, data about real-world objects are drawn quickly and can be shown using the different attribute fields stored in GIS databases. The sources for spatial data can be from different sources including field observation/measurement, GPS-based data collection, remote sensing, and software-based derivations like map digitization. Nowadays, satellite-based data acquisition is providing continuous image products for almost all areas of the world at different spatial resolutions.
Remote sensing is a valuable data source to obtain information about the surface of the earth. The applications of remotely sensed data are extremely broad, and it is increasing exponentially due to recent improvements in data resolution and availability. Several platforms have been historically used to consolidate data, starting from kites to balloons, airplanes, satellites, and very recently, drones.
Drought is a natural hazard that results from lower levels of precipitation than what is considered normal. When this phenomenon extends over a season or a longer period of time, precipitation is insufficient to meet the demands of human activities and the environment. Monitoring this phenomenon is has paramount importance.
Flood hazard assessment can be conducted in different ways depending on the availability of data. The method of carrying out the assessment depends on the information, technology, and resources accessible.
Disaster risk management, as a process, can be seen from different points of view; some of these include processes from the hazard, disaster governance, and disaster cycle points of view.\\\\
