Topological Segmentation of 2D Vector Fields

Vector field topology has a long tradition as a visualization tool. The separatrices segment the domain visually into
canonical regions in which all streamlines behave qualitatively
the same. But application scientists often need more than just a
nice image for their data analysis, and, to best of our knowledge,
so far no workflow has been proposed to extract the critical
points, the associated separatrices, and then provide the induced
segmentation on the data level.
We present a workflow that computes the segmentation of the
domain of a 2D vector field based on its separatrices. We show
how it can be used for the extraction of quantitative information
about each segment in two applications: groundwater flow and
heat exchange.
