Introduction

This is a course project for GIS and Geoinformatics Lab in 2020 Fall at ETH Zurich. With Microsoft HoloLens, our application, HoloInspect, provides additional mixed reality support for traditional BIM software in three construction stages: presentation, management and on-site inspection, with partial multi-user capabilities.
