Geo-data acquisition through mobile GIS and digital video: an urban disaster management perspective☆
Section snippets
Software availability
Two different types of software packages were tested. One group was tested with the objective of analysing the capacity to import points internally tracked by the GPS and export them into a GIS. The second group was tested with the objective of analysing the capture of still images from digital video. ArcPad proved the most adequate software for handling GPS data; it is user-friendly and it allows to virtually skip several steps since it constitutes a mini or light version of ArcView that has
Geo-information for strategy formulation
Informed decisions are a prerequisite for the formulation of successful mitigation, response, preparedness and recovery strategies. To a large extent, however, successful strategies depend on the availability of accurate information presented in an appropriate and timely manner. Information is also important as it increases the transparency and accountability of the decision-making process and it can therefore contribute to good governance. Initiatives such as the global disaster information
GIS and remote sensing
Problems associated with hazard identification, risk assessment, and developing mitigation solutions are inherently spatial in nature. New and emerging technologies make it feasible to automate labour-intensive tasks and to change dramatically the way emergency management is conducted (Federal Emergency Management Agency, 1997). Important emerging technologies include mobile geographic information systems (Mobile GIS), high-resolution digital remote sensing (RS) imagery, global positioning
Methodology for ground data capture
During the last decade, there has been a trend towards a decrease in the amount of research into field data collection. In the developing world, however, one of the biggest bottlenecks relates to the availability of spatial and attribute data. This problem is sometimes caused by the lack of a geo-spatial data infrastructure policy, but also by the high cost of conventional data collection and data processing methods. There is no doubt that remotely sensed imagery is useful in raising the
Conclusions
The city of Cartago provided an interesting case study; it represents a typical example of a medium-sized (e.g. 150 000 inhabitants) Costa Rican city that is located in a highly hazard-prone area and which has been devastated by earthquakes and lahars (mudflows of volcanic origin) on a number of occasions. The municipal government is severely financially constrained and there are very limited data available for the purpose of building loss forecasting of natural disasters. The method developed

Multicriteria decision making for selecting an optimal survey approach for large building portfolios
2022, International Journal of Disaster Risk ReductionCitation Excerpt :The first alternative (T2) is the mixed-mode survey approach presented in Opabola et al. [10]. The second alternative (T3) is the combination of GIS, GPS, digital video from moving vehicles, and information from a past census similar to that described in Montoya [5]. Finally, the third alternative (T4) is the use of terrestrial laser scanners (TLS) similar to that described in existing literature [16,17].

2022, Urban ClimateCitation Excerpt :Understanding the scope of disaster management from the perspective of management stage, disaster mitigation involves risk evaluation and reduction of the potential impacts of disasters and post-disaster activities to reduce potential damages from future urban hazards. Response describes the activities that occur during and immediately after a disaster to provide assistance to victims of urban disasters and to reduce the secondary potential damage (Montoya, 2003). Sustainable approaches to natural disaster mitigation recognize that natural processes and human activities are interconnected to produce disasters, and therefore most problems and solutions are also interconnected (El-Masri and Tipple, 2002).

2019, International Journal of Disaster Risk ReductionCitation Excerpt :The monitoring system developed by Liu et al. [33] focused on prevention of the disasters caused by magnetic storm facilitated by power system data, geomagnetic data, satellite data, and other earth space observation data and their processing over the Clouds. Montoya [55] explored the use of low cost and rapid method of data collection for the development of inventory based on the combination of various technologies such as RS, GPS, Digital Video and GIS with multistage operations and analysis for prevention of disaster situations. Eriksson et al. [87] developed a Cloud-based architecture for simulating the pandemic influenza so as to be able to prevent the chaotic environment caused by influenza.
