Trabajo desde hace años en aplicaciones que combinan datos abiertos de distinta procedencia para resolver un problema que parece sencillo y no lo es tanto: representar el modelo 3D de cualquier municipio español, con una altura que no sea un promedio inventado o procedural ni un valor por defecto según el número de plantas catastrales, sino una medición real extraída de la nube de puntos LiDAR del Plan Nacional de Ortofotografía Aérea.

Geografía financiera de Castilla y León · análisis espacial de POIs Open Data 2026
El análisis de la distribución espacial de servicios financieros en centros urbanos —bancos, cajeros, aseguradoras, gestorías y corredurías de seguros— ofrece una lectura directa de la vitalidad económica y la accesibilidad financiera de un territorio. Mapear estos puntos con assetIQ sobre datos Overture Maps permite identificar en minutos dónde se concentra la actividad financiera, qué zonas quedan en la periferia del servicio y cómo se estructuran los ejes comerciales de cada ciudad. El mismo análisis es replicable para cualquier otra capa temática —alojamiento, salud, restauración, deporte— convirtiendo cada capital de provincia en un dashboard geoespacial comparable y reproducible.
POI Intelligence for Urban Asset Analysis in RStudio: assetIQ
When analysing urban assets, there is genuine value in moving beyond generic neighborhood scores. The density of a coffee shop cluster, the proximity to a financial hub, or the concentration of accommodation around a transport node are signals that traditional datasets flatten into averages — or ignore entirely. assetIQ was built to change that. assetIQ is an R application powered by DuckDB and Overture Maps that extracts, classifies, and scores Points of Interest (POIs) for any location on Earth. You define a city and a search radius — from 100 meters to 25 kilometers — and the tool queries the Overture Maps Places dataset in real time, classifying each POI into thematic groups: Food & Drink, Retail, Health, Education, Transport, Accommodation, Financial Services, Leisure & Culture, Sport, and more.
The core output is an attribute value called POIQ: a normalized 0–1 score assigned to every building footprint within the area of interest, derived from a Kernel Density Estimation of the selected thematic group. A building in a dense retail corridor scores close to 1. An isolated residential block far from any commerce scores close to 0. This transforms thousands of individual points — which in raw form tell you very little — into a single, interpretable attribute per building, ready for downstream modelling, valuation, or site selection.
Detecting Potential Mobile Coverage Gaps Using OpenCellID, GHSL and Overture Maps: Case study over TUNIS
Mobile connectivity has become a fundamental component of modern infrastructure, yet significant spatial inequalities in network access still persist across both urban peripheries and rural environments. Using openly available geospatial datasets, this analysis explores potential mobile coverage gaps by combining OpenCellID cellular infrastructure observations, GHSL population layers and vector data extracted from Overture Maps. The objective is not to reproduce real telecom propagation models, but to generate a simplified spatial estimation of coverage capable of identifying populated areas potentially located outside the influence of nearby cellular infrastructure.
From Overture Maps to GPKG in minutes: Building a Geospatial Data Extractor with R and DuckDB
Modern geospatial workflows increasingly depend on fast, reliable access to city-scale vector data — building footprints, road networks, land use polygons, points of interest, address databases. Whether you are designing a 5G radio network, modelling urban heat islands, planning last-mile logistics, or simulating emergency response coverage, you almost always start from the same question: “How do I get clean, structured geodata for this city, right now, without spending two days on it?”
The Overture Maps Extractor is my answer to that question. It is a Shiny application written in R that lets any GIS professional extract multiple thematic layers from the Overture Maps Foundation dataset — for any city in the world — in a matter of minutes, with zero command-line interaction and zero manual data wrangling.
