computeSLParticles(rasterTransfo, demHeader, particlesX, particlesY)[source]

find the closest s, l coordinates in the aimec/thalweg coordinate system to a particles x,y location

Parameters

  • rasterTransfo (dict) – info on rasterTransformation, here gridx, gridy coordinates

  • demHeader (dict) – dict with info on dem xllcenter, yllcenter

  • particlesX (np array) – x coordinates of particles location for one time step but all particles (origin 0,0)

  • particlesY (np array) – Y coordinates of particles location for one time step but all particles (origin 0,0)

Returns

sList, lList – list of s, l coordinates for respective particle

Return type

list
