Global Height
We’re happy to announce the first version of 3dbuildings Global Height.
Since early days of our business, building height has been the most requested information attribute. Besides footprint, it’s the information that’s needed to turn flat geometry into 3d.
Global Height creates an impression about surroundings when marketing real estate, simulation of elements such as wind, water and noise.
It’s viable for radio frequency assessment in urban areas where potential antenna spots have to be determined as well as areas hidden from their signal. Energy efficiency analysis would be almost impossible to do without knowing built up volumes.
So far coverage of building height is about 90 million buildings. An impressive number, but only 14 % of our total data available. Percentage is much better in urban areas where it can be up to 80 %. Although cities are most important and most requested, we were not happy with these numbers.
For more than a year, we worked hard to provide full coverage of building height information — Global Height.
The technology is a combination of several analytical approaches as well as machine learning in order to classify built-up areas. For this first iteration we are mostly using our existing building data.
But we are not done yet. Next versions will involve global surface information, point data and a more extensive processing of buildings and their surroundings.
