Building footprint layers are useful in preparing basemaps and analysis workflows for urban planning and development. They are also used in insurance, taxation, change detection, infrastructure planning, and a variety of other applications. This deep learning model is used to extract building footprints from high-resolution (15–25 centimeter) imagery.
Digitizing building footprints from imagery is a time-consuming task and is commonly done by digitizing features manually. Deep learning models have a high capacity to learn these complex workflow semantics and can produce superior results. Use this deep learning model to automate this process and reduce the time and effort required for acquiring building footprints.
