Accurate maps of building interiors are essential for the development and deployment of indoor navigation and tracking systems; however, these maps do not exist for many buildings. This demonstration will present an efficient and accurate process that we developed for mapping the interiors and exteriors of buildings. The process uses Paracosm’s PX-80 handheld lidar scanner to collect 3D data on the buildings. It also uses Paracosm’s Retrace and ESRI’s ArcGIS software to both classify features in the lidar point cloud and extract information relevant to first responders. We mapped features ranging in size from recessed sprinkler heads, to fire alarms, to doors and windows. The entire process takes 20-30 hours for a 175,000 square foot building and requires little training and no technical background.
