Using Bitmap Index for Interactive Exploration of Large Datasets

  title={Using Bitmap Index for Interactive Exploration of Large Datasets},
  author={Kesheng Wu and Wendy S. Koegler and Jacqueline Chen and Arie Shoshani},
Many scientific applications generate large spatiotemporal datasets. A common way of exploring these datasets is to identify and track regions of interest. Usually these regions are defined as contiguous sets of points whose attributes satisfy some user defined conditions, e.g. high temperature regions in a combustion simulation. At each time step, the regions of interest may be identified by first searching for all points that satisfy the conditions and then grouping the points into connected… CONTINUE READING
