Abstract: This paper presents an evaluation of the mqr-tree for indexing a database of line data. Many spatial access methods have been proposed for handling either point or region data, with the vast majority able to handle these data types efficiently. However, line segment data presents challenges for most spatial access methods. Recent work on the mqr-tree showed much potential for efficiently indexing line data. We identify limitations of the data sets in the initial evaluation. Then, we further evaluate the ability of the mqr-tree to efficiently index line sets with different organizations that address the limitations of the initial test. A comparison versus the R-tree shows that the mqr-tree achieves significantly lower overlap and overcoverage, which makes the mqr-tree a significant candidate for indexing line and line-segment data.
