Thus,the COVID-19 spatiotemporal patterns are largely shaped by the underlying population patterns... [more]

Coverage and optimal visibility based navigation using visibility analysis from geospatial data
Oren Gal and Yerach Doytsher
In this paper, we study the multi-sensors placement optimization problem in 3D urban environments for optimized coverage. The solutions presented in this paper can be used, among other algorithms and solutions, to enable optimal coverage and moreover optimal trajectory planning and navigation based on an optimal visibility points...
