Geographic analysis tools have been used by the health sector for sanitary policy, epidemiological, surveillance and health promotion purposes. In order to track the COVID-19 pandemic, the Ministry of Health and the Technological Research and Innovation Laboratory (LIIT-UNED) of Costa Rica, launched a technological solution using open source softwa...

Tropical dry forests (TDF) are commonly affected by wildfires, especially during the dry season and drought periods. Many studies have identified ecological, pedological, and climatic variables that control fires ignition as well as other anthropogenic causes. Nonetheless, the intrinsic geomorphometric variables that shape the different TDF landsca...

Space-based Earth Observation allows us to simultaneously detect changes on Earth's surfaces over a large area. As a result, it's often used to assist with disaster assessments to understand associated property damages in the affected areas. Geographic Information Systems and Remote Sensing, are very popular for their applications in handling disas...

According to the United Nations Office for Disaster Risk Reduction, 1 the number of global weather-related disasters in the past decades has been estimated at 90% of the total number of disasters. These are likely to increase in severity and frequency with current and forecasted global climate changes. Disaster risk monitoring using space technolog...

In tropical dry forests, wildfires are likely to become a major disturbance as a result of anthropo-genic pressures and dryer conditions due to climate warming. Based on remote sensing techniques , this paper assesses the probability of fires occurring in the dry region of the Guanacaste Conservation Area (GCA), northwestern Costa Rica, testing the...

Los análisis post incendio, como el índice de área quemada (IAQ), permiten discriminar áreas afectadas y severidad de los incendios forestales. En este estudio se comparó según la frecuencia de incendios, el comportamiento anual del IAQ en la región de bosque seco tropical del Área de Conservación Guanacaste, Costa Rica entre los años 1997 al 2019....

In the current era of changing climates and rapid demographic growth, the intensity and frequency of natural hazards are increasing rapidly across the globe, often interacting in a given spatial region and/or temporal period. As a result, natural disasters - when the occurrence of a natural hazard has a significant impact on a community - are on th...

Wildfires occur in almost every type of ecosystem. However, vulnerability and propagation capacity of wildfires mostly relies on the amount of biomass and their water content. Particularly, Tropical dry forests are a vulnerable ecosystem to wildfires because, have at least six months with a precipitation of less than ten mm per month. Vulnerability...

El bosque tropical seco ubicado en el pacífico norte de Costa Rica es afectado de forma recurrente por incendios forestales, lo que impulsa cambios en la dinámica del paisaje, así como en los valores socioeconómicos y ecológicos del ecosistema. El objetivo del estudio es determinar las relaciones de la geomorfología en la vulnerabilidad a incendios...

Por décadas la detección y el monitoreo de coberturas de la tierra se ha llevado a cabo por medio de teledetección aéreo-transportada y satelital. La habilidad de detectar y cuantificar coberturas de la tierra depende en gran medida de las capacidades del sensor y técnicas de clasificación entre las cuales destacan supervisada, no supervisada y mix...
