Module Hierarchy

• pyrdnap: A pure Python implementation of the 2018 version of Netherlands' RD NAP specification to convert between GRS80 (ETRS89) geodetic lat-, longitudes and height and local RijksDriehoeksmeeting (RD) coordinates and Normaal Amsterdams Peil (NAP) quasi-geoid-height.
  • pyrdnap.__main__: Run a RD NAP 2018 forward or reverse conversion example or run the NSGI or RD NAP 2018 validation test set in "round-trip" fashion.
  • pyrdnap.__pygeodesy: (INTERNAL) pyrdnap access to some private pygeodesy attributes.
  • pyrdnap.rd0: (INTERNAL) RijksDriehoeksmeting _RD and reference _RD0 constants and classes RDNAP7Tuple and LqRD.
  • pyrdnap.rdnap2018: Main classes RDNAP2018v1 and RDNAP2018v2 follow variant 1 respectively variant 2 of the RDNAPTRANS(tm)2018_v220627 specification.
  • pyrdnap.v1grid: Extract from the original, compressed, variant 1 grid files nlgeo2018.txt.zip and rdcorr2018.txt.zip the NAP_..., lat_corr_ and lon_corr_ columns only and encode each in Python as a row-order matrix, a 481-tuple of 301-arrays of single- or double precision floats.
  • pyrdnap.v2grid: Extract from the original, compressed, variant 2 grid files naptrans2018.txt.zip and rdtrans2018.txt.zip the NAP_..., lat_corr_ and lon_corr_ columns only and encode each in Python as a row-order matrix, a 481-tuple of 301-arrays of single- or double precision floats.
  • pyrdnap.v_grids: (INTERNAL) RD NAP 2018 v#grid utilities.
  • pyrdnap.v_self: Function validation3 to run the RD NAP 2018 self-validation test set .../RDNAPTRANS2018_v220627/.../Z001_ETRS89andRDNAP.txt obtainable from NSGI.NL after registration.
