Interpreting wombling maps: raster data

The layer types that appear are listed below; the name of each layer includes its boundary name (e.g. "Boundary 1: boundary links"), though a few types have no suffix (e.g. "Boundary 1"). As the locations of candidate Boundary Elements vary between numeric and categorical rasters, each type of raster has some specific map layers.

You can view, customize, and query these maps as you would any other map in BoundarySeer.

Map layers

numeric data, crisp wombling

  1. "Boundary" is a raster layer showing Boundary Likelihood Values (BLVs) for boundary pixels. Boundary pixels are centered on the candidate Boundary Elements (cBEs).

  2. "Boundary: boundary links" is a line layer showing the subboundary connections for the boundary.

  1. "Boundary: boundary points" is a point layer that shows Boundary Elements as points along the edges of the data pixels.

numeric data, fuzzy wombling

  1. "Boundary" is a raster layer showing BLVs for boundary pixels. Boundary pixels are centered on the cBEs.

categorical data (only available with Grid ASCII import)

  1. "Boundary" is a line layer showing the lines for which BMV = 1 for crisp boundaries.
