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.
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).
NO AL PELOTAZO DE LA ERMITA DEL SANTO
Esta semana pasada he estado colaborando puntualmente con la Plataforma “planermitadelsanto”, vecinos como yo que se han (nos hemos) organizado para echar abajo un plan de recalificación urbanística que no es ni mucho menos del interés general. He preparado para ellos algunos mapas en 3D (georeferenciando planos, extruyendo manualmente usando datos del Plan propuesto, realizandoContinue reading “NO AL PELOTAZO DE LA ERMITA DEL SANTO“
Google Earth Engine and Dynamic World
Let me please introduce you this “new” LULC source I have come across with recently. The potential of this 10m “clutter” source is being able to acquire data from a few days ago instead of using outdated “very old” 2020 vintage datasets. I know if these days something 2020 is very old then myself, born in 1972 then i’m older than the riverside, older than peeing in a wall, even older than Methuselah. Yes, that’s the way it is nowadays.
Google Earth Engine is a geospatial processing service where you can perform geospatial processing at scale, powered by Google Cloud Platform. The purpose of Earth Engine is to:
Provide an interactive platform for geospatial algorithm development at scale
Enable high-impact, data-driven science
Make substantive progress on global challenges that involve large geospatial datasets
Measuring moisture: Normalized Difference Moisture Index (NDMI) Sentinel-2 2022
I am here in front of my desktop and I wonder how to take advantage of Sentinel Hub for tracking up moisture in a random plot anywhere in the world. Has it been irrigated at the right time for the type of crop? How has rainfall been affected over the analysis time? How has the use of certain fertilisers affected it? Has it positively affected production?. Let’s take a closer look.
Marathon à Nantes 2022: CHECKED!
J’ai toujours cru que faire les choses selon un plan facilitait la réalisation de ce que vous aviez prévu de faire, eh bien, quand il s’agit de courir un Marathon, c’est la clé. Lors de mon troisième Marathon après Valencia en 2017 et Madrid en 2019, on constate une meilleure tendance par rapport au nombre de kilomètres de préparation.
