How do heat maps work?

In this new post we want to see what heat maps are and what applications they have. They are nothing more than graphics that allow us to identify the hot spots in a certain space, where there is a higher concentration of people. One of the specialities of our company, which is walking hand in hand with the development of smart cities in Spain, in which we are fully active.

At the heart of how heat maps work is thermography. Heat maps use a hierarchy of colours in which, as a rule, the points of most interest are identified by the warm colour ranges. That is, red, orange and yellow. In contrast, the areas of least interest are represented by cool colour ranges such as green, blue and turquoise. In this way, the heat map establishes the hot spots that exist in a location, the places where people go and stay most often, i.e. the places that they like and attract their attention the most. Heat maps are also perfectly applicable in the retail sector, for example to see which parts of a shop attract the most attention from customers.

Capacity control and people flow analysis

Dinycon has developed a technology based on heat mapping that allows you to visualise real-time capacity with details of entrances and exits at access gates. It also allows you to analyse the flow of activity through heat mapping with omnidirectional cameras to trace the movement of people in transit areas. As you can see, this solution provides complete activity maps, which is extremely necessary for counting and control of capacity and for analysing the flow of people. It allows companies and public bodies to make profitable and optimise the allocation of resources, control dangerous crowds, better manage events and, of course, comply with safety regulations in public establishments and venues.

Some fields of application of heat maps are:

  • Events and shows
  • Museums and exhibitions
  • Trade fairs and congresses
  • Sports establishments
  • Public buildings
  • Transport
  • Public roads

A good example of how heat maps can be applied in the management of smart cities is the one illustrated in this post, with the projects launched in Donostia and Santander.
