​Geocoding of buildings

​In cooperation with Danish surveying company LIFA, COWI carried out digital geocoding of the buildings owned by the Municipality of Solrød. This was done to optimise the municipality's registration and management of building data. The method took some getting used to, but today the municipal residential building inspectors are thrilled with the result.

​Geocoding buildings is a way to localise information from the Danish building and dwelling register (BBR) on digital maps. BBR information is presented on geographical maps, providing a clearer and more structured overview of building data. This also allows you to carry out a range of geographical analyses.

COWI endeavours to deliver valid building geocoding. In other words, focus is on quality rather than quantity, which means that the Municipality of Solrød can rely on the validity of COWI's geocoding. It is also important to COWI to ensure that ge-ocoding creates value for each inspector and for the municipality as a whole. 

Practical tests demonstrate the advantages of build-ing geocoding

Geocoding buildings is an extensive process, in particular because some buildings may be difficult to geocode, which entails challenges that might obscure the advantages of the method.

According to Laila Nissen, GIS Coordinator at the Municipality of Solrød, the residential building inspectors in the municipality "…were used to solely working with the building and dwelling register, and the geographical dimension that geocoding offers was not thought to hold any special value". Consequently, the inspectors first struggled to see the advantages of building geocoding.

To win them over, different tests/pilot demonstrations were made. According to Nissen, this approach proved successful: "By having the inspectors tackle practical tests, we managed to overcome their negative focus on the challenges presented by geocoding."

Live and easy-to-grasp building data through building geocoding

According to Nissen, today, the inspectors believe in the advantages of geocoding, and most of the buildings in the Municipality of Solrød have been geocoded. Geocoding helps building data from BBR to come alive, especially through colour themes/categorisation. The municipal buildings have gone from merely being regis-tered to being geographically visual. Nissen is convinced that geocoding will make its way into other areas in the municipality, including the private sector.
