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)”
Digital Twin. Real-Time Public Transportation Visualization on LiveMaps360.com
The primary feature of LiveMaps360.com is its ability to display public transportation data in real-time. By integrating data from Tokyo’s extensive public transportation network, including buses, trains, and subways, the website enables users to track the movement of vehicles and access critical information such as arrival times, routes, and service disruptions.
The beauty (and precision) of LIDAR:
Lidar, which stands for Light Detection and Ranging, is a technology that uses laser beams to measure distances and create detailed maps of the surrounding environment. It works by emitting laser pulses and then measuring the time it takes for the pulses to bounce back after hitting objects in their path. By analyzing the returning signals, lidar can accurately calculate the distance to various points and generate a three-dimensional map.
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).
Uso de ChatGPT en diferentes idiomas para generar post sobre un tema random: “autómatas celulares”
¿Pensáis que la Inteligencia Artificial de ChatGPT nos permite autoescribir de manera completamente automática sobre un tema random como este (autómatas celulares/cellular automata) una introducción para por ejemplo hacer un post en redes sociales?. ¿E ir más allá?. Quizá no estemos tan lejos de que los robots empiecen a pensar por nosotros. Paso uno, usoContinue reading “Uso de ChatGPT en diferentes idiomas para generar post sobre un tema random: “autómatas celulares””

Faible taux d’humidité au Pays Basque. Sérieux ?
Quand vous venez passer le week-end dans un village du Pays Basque et que vous voyez cette image verte ci-dessous, vous vous dites, ho-ho, ici ils n’ont pas eu les problèmes de chaleur et de manque de pluie que nous avons subis dans le centre et le sud de la péninsule. Mais tout à coup, ils vous disent que oui, ils ont aussi souffert et qu’il est impossible qu’ils aient atteint les niveaux d’humidité des autres années…
Inland Water levels… Globally. Copernicus did it again!
The Water Observatory is an Earth-observation-based solution that provides reliable and timely information about surface water levels of waterbodies across the globe. All observations are provided and can be explored interactively via the Water Observatory Dashboard or via RESTful API. The Water Observatory provides a valuable service to local authorities, governmental agencies, natural parks and reserves, agricultural ministries and agencies, stakeholders in food and energy production, and citizens alike.
