A notable tool called Cercalia RealState, created by Nexus Geographics, offers the ability to replicate the movements of the sun in any given area. By using this platform, we can accurately predict the lighting and shadow patterns that a particular property will experience throughout the day. This invaluable tool is truly a wonder for people looking for a home with their preferred orientation.

This is an incredible resolution to address the needs of the real estate industry. Salvador Carbó, director of Cercalia at Nexus Geographics, describes the history in which his company was founded in 1997 as "a historic player in the GIS industry." With offices in both Barcelona and Gerona, this company has a team of just over 60 people and plans to exceed a turnover of four million euros next year.

Their resolution proposals address both the public and private spheres, and they were pioneers in introducing "our own Google Maps." Interestingly, the initial iteration dates back to 2002 and Cercalia was subsequently established with a primary focus on addressing logistical challenges.


In today's world, the platform and mapping solution offered by Cercalia, a discipline that is at risk of disappearing, has become much more important. It now handles approximately 15 million requests per day. According to Carbó, the main emphasis is on logistics. For example, Envialia uses Cercalia to optimize its routes. In addition, Interfacom, an important technology group in the taxi sector, trusts in this platform for its GEO functionalities.

Another key area of ​​focus is insurance companies. Carbó highlighted that Cercalia offers a unique system to locate roads and kilometer points, which is crucial when sending cranes to problem areas. This system works in Spain, France and Portugal and is not even available on Google Maps.

One aspect that stands out is the company's emphasis on the real estate sector. Cercalia RealState has successfully addressed an important market need by giving customers the ability to determine the presence of direct light and shadows in their homes.

The company offers a variety of options, including high-cost solutions like Google Maps (which Carbó describes as "the most expensive"), as well as cheaper alternatives like Here and Mapbox (which are more affordable if they don't have high usage). . In addition, they also offer free solutions, such as OpenStreetMaps.

According to the manager, Cercalia is not only a more profitable option compared to Here or Mapbox, but it also offers a fixed annual rate that aims to meet the needs of its clients. Speaking of which, the garden in question has abundant sunlight until 5 pm, making it an ideal place for pleasant gatherings with friends.

While it primarily caters to filmmakers and photographers, there is competition in this field, exemplified by alternatives such as 'The Photographer's Ephemeris' or Sun Intervals, which specialize to a certain extent. However, Cercalia's offering stands out above all for its impressive "shadowless" mapping service.
