About Goolzoom

Goolzoom is a project born in December 2006 and developed by Jesús Barrio as an idea to facilitate access to the Cadastre from Google Maps. Today, they are a set of utilities that facilitate access to all types of public domain data and real estate information, without losing the same original spirit of providing transparency and simplifying access to data that is in the public domain.

What we are passionate about

We don't want to bore you by telling you why we put thousands of hours into our work. But we found these three icons in a library to summarize it.

Rack one's brain

To find great ideas, to make our contribution to the technological development and, in summary, to change to better our small world.

Programming like nerds

Sir Arthur C. Clarke said, "Any sufficiently advanced technology is equivalent to magic," that's what we like to do.

Create useful tools

Because we live in a world of buzzword sellers and technohomeopathic charlatans. We prefer to just do useful things.
