2025 A lightweight GitHub Actions workflow captures near-real-time global aircraft positions, making it possible to reconstruct events such as sudden airspace closures during conflicts.
This explainer maps what is at stake in occupied Ukrainian territory, combining front-line evolution with strategic assets such as infrastructure, resources, and energy nodes.
2024 Based on extensive field measurements, this project reconstructs the peak flood level in Paiporta and nearby towns, showing the full magnitude of a water mass that exceeded three meters in many streets.
2024 This story contextualizes the Valencia flood through rainfall, discharge, and inundation records, showing an event with an estimated return period above 1,000 years and, in some expert assessments, closer to 5,000.
2024 A map-driven explainer on the Kursk offensive, contrasting Ukrainian advances inside Russia with simultaneous Russian gains in Donetsk through a clear temporal and territorial reading.
2024 This project documents how armed activity reappeared in parts of Gaza that had been presented as dismantled, connecting military operations, territorial control, and civilian impact through map-based chronology.
2024 A very interesting utility to build inset maps for Mapbox scenes that include bearing and pitch, solving a gap where no native option exists.
03
2024 A tiny utility to calculate the exact scale ratio between ai2html artboards, helping map and graphics workflows move faster in Adobe Illustrator.
2024 Cheesy Shadow Picker is a lightweight utility for testing readable text-shadow combinations on maps and imagery, with instant visual feedback and copy-ready CSS output.
This explainer links DANAs, Mediterranean cyclones, and medicanes through a real recent case, showing why extreme rainfall events in the region are becoming more destructive.
2023 Interactive generator for Poisson-disc point clouds with rectangle and circle modes, export options, and controls tuned for newsroom graphics workflows.
2023 A fast-turnaround wildfire explainer that uses terrain, vegetation, and wind context to show why the Tenerife fire spread so aggressively in a very short time.
2023 A reconstruction of wildfire containment strategy in Catalonia, showing how real-time operational data, tactical decisions, and terrain constraints shaped the response under pressure.
A long-form visual explainer on Antarctic ice change that combines satellite-derived elevation data, cartographic experimentation, and narrative graphics to show where the continent is gaining or losing ice mass.
2022 This calculator helps readers estimate mortgage installments under changing Euribor scenarios, allowing fast what-if testing with a simple and practical interface.
2022 This piece examines the post-eruption volcanic tube system in La Palma and quantifies how much new material was deposited, linking subsurface structures to the transformed surface landscape.
This investigation traces vessels linked to grain extraction from occupied Ukrainian territories, documenting evasion patterns such as AIS shutdowns and opaque route behavior.
2022 A forensic reconstruction of the Melilla border tragedy based on geolocated videos, witness accounts, and synchronized timelines to establish a verifiable sequence of events.
2021 This explainer interprets key eruption indicators in La Palma—seismicity, tremor, and deformation—to clarify what each signal suggests about volcanic evolution and near-term risk.
2021 A historical performance analysis of the 100-meter sprint, comparing record eras, competitive ceilings, and persistent outliers through a clean visual narrative.
2021 Authorities risk's maps reveal that one third of the population is exposed to high or very high levels of seismic hazard. Researchers analyze the risks to prevent the probable damage of a major earthquake in the country.
2021 A continuously updated COVID-19 tracker for Spain that consolidated national and regional indicators into a single view for fast, reliable public consultation.
2021 A long-form visual story on the retreat of Spain's last glaciers, combining field reporting, scientific measurement, and 3D cartography to show how fast high-mountain ice is disappearing.
2020 An unprecedented high-resolution mortality map of Spain that lets readers explore major causes of death at municipal scale while preserving statistical context and territorial comparability.
A comparative analysis of coalition governments across 38 European countries, showing that multiparty agreements are a structural norm rather than an exceptional political outcome.
Project developed by Datadista showcasing their coverage of the 2019 general elections for RTVE, the state-owned public corporation responsible for Spain's radio and television services. The project includes scatter charts, cartograms, and numerous maps.
2019 Transparentia lets you to check more than 9.600 salaries of politicians and public workers. We wanted to answer a simple question: how many politicians are there in Spain and how much are they paid.
2017 We analyzed how the Olympics changed Barcelona forever on the 25th anniversary of the games using aerial images.
2017 Exploring remote sensing through an analysis of two practical applications of the Difference Normalized Burn Index, focusing on the assessment of the severity of two major fires in Spain using Landsat 8 imagery.
2016 Maps about the presence of Spanish armed forces in Italy, Turkey and Lebanon.
04
