*Environment Mapping and Urgent Landing Planning for Low-Altitude UAS
Operations*

*Abstract: *Small Unmanned Aircraft Systems (sUAS) are expected to
proliferate in low-altitude airspace over the coming decade requiring
flight near buildings and over people. Robust urgent landing capabilities
including landing site selection are required. However, conventional
fixed-wing emergency landing sites such as open fields and empty roadways
are rare in and around cities. Our work uniquely considers a city's many
unoccupied flat rooftops as possible nearby landing sites. We propose novel
methods to identify flat rooftop buildings, isolate their flat surfaces,
and find touchdown points that maximize distance to obstacles. We model
flat rooftop surfaces as polygons that capture their boundaries and
obstructions. We process satellite images, airborne LiDAR point clouds, and
map building outlines to generate rooftop maps with a multi-stage machine
learning pipeline. We propose a computational geometry method (Polylidar3D)
that reliably extracts flat rooftop surfaces from archived data sources. We
model risk as an innovative combination of landing site and path risk
metrics and conduct a multi-objective Pareto front analysis for sUAS urgent
landing in cities. A high-fidelity simulated city is constructed in the
Unreal game engine with a statistically-accurate representation of rooftop
obstacles. A summary of complementary research in contingency planning and
airspace geofencing will conclude the presentation.

Michigan’s Aerospace Engineering Department where she directs the
Autonomous Aerospace Systems (A2SYS) Lab and is Associate Director of the
Robotics Institute. Dr. Atkins holds B.S. and M.S. degrees in Aeronautics
and Astronautics from MIT and M.S. and Ph.D. degrees in Computer Science
and Engineering from the University of Michigan. She is an AIAA Fellow,
private pilot, and Part 107 UAS pilot. She served on the National Academy’s

Analysis Defense Science Studies Group. She has served on several National
Academy study committees and co-authored study reports including Advancing
Aerial Mobility A National Blueprint (2020) and Autonomy Research for Civil
Aviation Toward a New Era of Flight (2014). Dr. Atkins has built a research
program in decision-making and control to assure safe contingency
management in manned and unmanned Aerospace applications. She is currently
Editor-in-Chief of AIAA Journal of Aerospace Information Systems (JAIS) and
a member of the 2020-2021 AIAA Aviation Conference Executive Steering
Committee.
