org.jgrasstools.gears.modules.v.contoursextractor.OmsContourExtractor.html Maven / Gradle / Ivy

Module that extracts contour lines from a raster. Algorithm comes from  jai-tools, which used  the Conrec contouring subroutine.




Inputs
      
the raster on which to calculate the contours
the minimum value for the contours
the maximum value for the contours
the contours interval





Output
      
the generated contour lines vector
 

Notes
The module has a couple of known issues:
      
it missbehaves if there are cell values that happen to be equal to the contour values (see above referenced article for further explanation).
isolines can accumulate at image borders
