Web maps for ports

I build the web maps and software that port authorities use to see what is happening in the port, plan it and react to it. I do it at APDL, the port authority of Leixões, Douro and Viana do Castelo, and before that for 11 years at 3Maps, building GIS platforms for ports and municipalities.

What I build

See the full list on Projects.

How I build

Mostly with open-source tools: MapLibre GL JS for the maps, PostgreSQL with PostGIS for spatial data, and Laravel with Vue for the applications. I try to keep things small and simple: low-cost solutions that port teams can run and maintain themselves. I wrote about that approach in a paper on open source in port authorities.

Open source

I also publish small open-source tools for MapLibre: SVG polygon patterns and label callouts, and I write about self-hosted map tiles.
