Abstract
An arrangement of curves in the plane is given. The query is a point and the goal is to find the face of the arrangement that contains . A data-structure for point-location, preprocesses the curves into a data structure of polynomial size in , such that the queries can be answered in time polylogarithmic in . We design a data structure for solving the point location problem queries in time using preprocessing time, if a polygonal subdivision of total size , with cell complexity at most can be computed in time , such that the order of the parts of the curves inside each cell has a monotone order with respect to at least one segment of the boundary of the cell. We call such a partitioning a curve-monotone polygonal subdivision.
