makeDomainTransfoOnTheGo(avaDir, dem, cfgSetup, pathDict)[source]

Make domain transformation

This function returns the information about the domain transformation Data given on a regular grid is projected on a nonuniform grid following a polyline to end up with “straightend raster”

Parameters

  • avaDir (pathlib path or str) – path to avalanche directory

  • dem (dict) – dictionary with header and raster data

  • pathDict (dict) – dictionary with paths to lines for Aimec analysis

  • cfgSetup (configparser) – configparser with ana3AIMEC settings defined in ana3AIMECCfg.ini regarding domain transformation (domain width w, and new cellsize, startOfRunoutAreaAngle or interpolation method, resType and referenceFile to get header info)

  • pathDict (dict) – dictionary with info on avalanche path, splitPoint, project name

Returns

rasterTransfo –

domain transformation information:
gridx: 2D numpy array

x coord of the new raster points in old coord system

gridy: 2D numpy array

y coord of the new raster points in old coord system

s: 1D numpy array

new coord system in the polyline direction

l: 1D numpy array

new coord system in the cross direction

x: 1D numpy array

coord of the resampled polyline in old coord system

y: 1D numpy array

coord of the resampled polyline in old coord system

rasterArea: 2D numpy array

real area of the cells of the new raster

indStartOfRunout: int

index for start of the runout area (in s)

Return type

dict
