Cell Computation Overview<br />

Sensor footprints can<br />

– Have no overlap with cell<br />

– Entirely overlap the cell<br />

– Partly intersect with the cell<br />

– Be contained within the cell<br />

Cell confidence depends on<br />

– LoS obstructions<br />

– Visibility factors<br />

– Detection factors<br />

– Amount of footprint(s)<br />

overlap<br />

– Age of observations<br />

– Speed of targets<br />

GIS Services should provide<br />

– Cell mobility factor<br />

– Line-of-sight occlusion<br />

– Terrain visibility factor<br />
