En Los Ángeles, la combinación de condiciones meteorológicas, como los vientos secos de Santa Ana y las altas temperaturas, crea un entorno propenso a incendios forestales. Estos fuegos, a menudo cercanos a áreas urbanas, representan un gran desafío para la gestión de emergencias. Aquí es donde Sentinel-2 se convierte en una herramienta crucial. Utilizando la combinación de bandas 12, 8, 4, Sentinel-2 permite detectar rápidamente focos de calor y evaluar la extensión de las áreas quemadas, lo que es vital para coordinar respuestas eficaces. Esta capacidad de monitoreo casi en tiempo real es fundamental para mitigar el impacto de los incendios y proteger tanto a las comunidades como a los ecosistemas.

Palestine 2023-2024
The 7th of October will forever be remembered in our collective memory as a day of tragedy and senseless violence, an operation that would shatter the dream of Israel’s inviolability. The attacks by Hamas were unequivocally condemnable. The targeting of civilians (+1200 dead and +250 kidnappings) is never acceptable, and those responsible for such acts must be held accountable. However, the response that followed has escalated into something far worse, a state-driven campaign of violence by Israel that has, in just one year, claimed over 42,000 lives, a staggering number of whom are women and children. This is not defense; this is mass murder. GENOCIDE.
Wildfires in Russia through SENTINEL 2
In recent days, the Sakha region in Russia has experienced significant wildfire activity, More than 100 wildfires spanning more than 300,000 hectares are currently active. driven by a combination of extreme weather conditions and environmental factors. The fires, which have spread across vast areas of forest and tundra, have been exacerbated by unusually high temperatures and prolonged periods of drought. These conditions have led to exceptionally dry vegetation, creating an ideal fuel for the fires.
Water Quality Viewer (UWQV) for Sentinel -2
The Ulyssys Water Quality Viewer harnesses the power of Sentinel-2 satellite data to provide comprehensive and accurate water quality assessments. Its intuitive legend and visualization capabilities significantly enhance the user’s ability to interpret and act on environmental data, contributing to better water management and conservation efforts worldwide, particularly in ecologically and economically significant areas like La Mata and Torrevieja salt lagoons.
Sequía en Cataluña – Timelapse 2017-2024
Las restricciones más duras de emergencia por sequía se extenderán a más de seis millones de personas de los 202 municipios de Barcelona y algunas poblaciones de Girona. Así lo ha anunciado este jueves la Generalitat, que suma estas localidades a las 37 (125.000 habitantes) de las comarcas de Alt Empordà, Baix Camp y Baix Llobregat, que ya estaban en la fase más severa desde agosto. Esto significa que casi el 80% de la población catalana vive en una zona en emergencia por la crisis hídrica.
The Remarkable Visibility of Almeria’s Greenhouses from Space
In the sphere of Earth observation and remote sensing, the Almeria greenhouses stand out as an astonishing spectacle visible even from the edge of space, defined by the Kármán line at approximately 100 kilometers in altitude. This unique visibility is not only a testament to the vast scale of human agricultural activity but also a captivating example of the power of satellite-based remote sensing technologies.
No words (or almost)
Visualization 12-11-4 Sentinel 2 in relation to events in and around the Gaza Strip in early October 2023. It is difficult to remain aseptic even when talking about something technical. I will only say that I am ashamed of the world today. I am ashamed of the rulers and the ignorance of those who followContinue reading “No words (or almost)”
I FORO NACIONAL: CIENCIAS DE DATOS ESPACIALES COMO HERRAMIENTA EFICAZ EN LA GESTION PUBLICA. Lima (Perú)
Esta pasada semana he tenido el honor de viajar a Lima (Perú) para participar en el el Primer Foro Nacional de Ciencias de Datos Espaciales como herramienta eficaz para la gestión pública estos pasados 18-19 Julio 2023 en el Centro de Convenciones de Lima, Perú. Mi ponencia era sobre el DIGITAL TWIN en la ciudad de CUZCO así como el BRIGHT EARTH CITY TEXTURING, una solución de texturización procedural con semántica 3D de bajo mantenimento de mi empresa Luxcarta, un gran adelanto tecnológico de nuestro departamento de I+D.
Learning to use GOES constellation
GOES satellites continually view the continental United States, Pacific and Atlantic Oceans, Central and South America, and Southern Canada. To fully cover Alaska, Hawaii, the entire continental United States and the Pacific and Atlantic Oceans (for tropical storms), NOAA operates two GOES satellites simultaneously
Measuring snow coverage using EOB – Earth Observation – Sentinel HUB
Playing with Sentinel 2 images I realized that the amount of snow this year has been very low compared to last winter. Here are a couple of images from January 2022 and 2023 of the Canfranc – Paticosa – Jaca area. One of the most interesting things about this EO browser is that in addition to a standard 2D visualisation, we can visualise in 3D. Here is an video example. Another interesting thing is to be able to quantify the snowfall. There is a snow classifier based on NSDI (Normalized Difference Snow Index, The Normalized Difference Snow Index (NDSI) snow cover is an index that is related to the presence of snow in a pixel and is a more accurate description of snow detection as compared to Fractional Snow Cover (FSC).
