1. 16. Optimizing the locations of bike-sharing stations using GPS-based trip data: A Spatio-temporal demand coverage approach

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Birkan Caliskan; [2022]
   Keywords : Geomatics; GIS; Bike-sharing; Genetic Algorithm; Location-allocation; Site selection; Optimization; Spatial Analysis; Earth and Environmental Sciences;

   Abstract : Shared micro-mobility services are increasingly embraced by cities around the world in recent years. Their benefits over other transportation modes in certain frames encourage traffic/urban planners, public authorities to establish such systems in urban areas. READ MORE

3. 17. The influence of climate, population density, tree species and land cover on fire pattern in mainland Portugal

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Luis Gomes; [2022]
   Keywords : GIS; forest fires; burnt Area; characteristic fire size; spatial analysis; mainland Portugal; FWI; Eucalyptus globulus; Earth and Environmental Sciences;

   Abstract : Forest fires in mainland Portugal are becoming more extreme, resulting in increasingly larger burnt areas and tragic human fatalities, as was shown by the 2017 fires. Research shows that there are many natural factors contributing to such fire vulnerability conditions, such as climate, fuel continuity, forest structure, tree species types, amongst others, that are intertwined with anthropic factors than can intensity the fire vulnerability.

4. 18. An Analysis of Spatially-enabled Mobile Decision Support Systems in a Collaborative Decision-Making Environment

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Mark Overton; [2022]
   Keywords : Geography; GIS; multi criteria decision analysis; mobile decision support system; route optimization; Earth and Environmental Sciences;

   Abstract : The effectiveness of decision-making processes has been enhanced by integrating multi-criteria decision analysis (MCDA) and geographic information system (GIS) methods to solve more complex spatial problems that were not possible to solve using conventional GIS methods. A spatial decision support system (SDSS) supports various stakeholders in the decision-making process, by processing data using GIS-MCDA methods. READ MORE

6. 20. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Annejet Tuinstra; [2021]
   Keywords : wildfires; debris flows; water repellent soil; North America; skogsbränder; jordskred; vattenavvisande jordlager; Nordamerika;

   Abstract : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. READ MORE
