Using quad trees to generate grid points for applications in geographic disease surveillance
Content Type: Abstract
In this study, we compare two methods of generating grid points to enable efficient geographic cluster detection when the original geographical data are prohibitively numerous. One method generates uniform grid points, and the other employs quad… read more… than the uniform scheme. The quad tree grid point scheme may be a useful alternative to the uniform (and other) grid … standard normal distributions to gen- erate x and y coordinates of 3,000 centrally clustered atomic data … the search system to find clusters using SaTScan version 7.0 (12) for the uniform and quad tree grid point generation …
