in3Utils.geoTrans.prepareLine

prepareLine(dem, avapath, distance=10, Point=None)

Resample and project line on dem 1- Resample the avapath line with a max intervall of distance=10m between points (projected distance on the horizontal plane). 2- Make avalanche profile out of the path (affect a z value using the dem) 3- Get projection of points on the profil (closest point)

Parameters

• dem (dict) – dem dictionary

• avapath (dict) – line dictionary

• distance (float) – resampling distance

• Point (dict) – a point dictionary (optional, can contain several point)

Returns

• AvaProfile (dict) – the resampled avapath with the z coordinate

• projPoint (dict) – point dictionary projected on the profile (if several points were give in input, only the closest point to the profile is projected)
