Testing GEMINI for 3D environments. From SketchUp to an unlikely future!

The exercise shows how a simple SketchUp 3D volume, defined solely by its basic geometry, can be transformed into a complex architectural proposal. Starting from the initial schematic model, the system interprets proportions, levels, and shapes, and converts them into a fully developed building, complete with textures, vegetation, lighting, and an urban context

Urban Heat Islands, Trees, and Climate Justice in the Anthropocene: A Remote Sensing-Based Reflection

In recent years, the need to understand the urban environment has grown more urgent than ever. Climate change is not an abstract future scenario; it is already here, reshaping our cities day by day. Among the many phenomena that demand our attention, the Urban Heat Island (UHI) effect stands out—not only for its environmental and public health impacts but also for its socio-political implications. Through satellite imagery and remote sensing, we can now visualize and quantify these dynamics with increasing precision. This post reflects on such an analysis I conducted using LANDSAT 8 imagery (Scene ID: LC08_L2SP_201032_20250328_20250401_02_T1, Date Acquired: 2025/03/28), and discusses the findings in the broader context of urban planning, climate justice, and the urgent need to protect urban vegetation.

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.

Taxing the sun?. Yes, in Spain this seems to be possible.

Absolutely ashamed by my government’s insane policies on this regards, Spain is now (…) attempting to scale back the use of solar panels – the use of which they have encouraged and subsidized over the last decade – by imposing a tax on those who use the panels. The intention is clearly to scare taxpayersContinue reading “Taxing the sun?. Yes, in Spain this seems to be possible.”
