Package v2grid
Variant 2 grid files, but only columns NAP_h_...,
lat_corr_ and lon_corr_ of the original
RDNAPTRANS2018_v220627/...2/naptrans2018.txt and
...2/rdtrans2018.txt grid files and encoded into Python as 3
row-order matrices, each a 481-tuple of 301-arrays of floats.
The combined size of these 3 grid files is 4 MB vs 9.8 MB for the
original 2.
- pyrdnap.v2grid.naptrans2018_txt_NAP_h: Variant 2 grid file
...2/naptrans2018.txt, only
the 3rd column NAP_quasi_geoid_height_...(m) and
encoded in Python as a 481-tuple of 301-arrays of floats.
- pyrdnap.v2grid.rdtrans2018_txt_lat_corr: Variant 2 grid file
...2/rdtrans2018.txt, only
the 3rd column lon_corr_(deg) only with
0.00* shrunk to 0.*, -0.00*
to -.* and encoded in Python as a 481-tuple of
301-arrays of floats.
- pyrdnap.v2grid.rdtrans2018_txt_lon_corr: Variant 2 grid file
...2/rdtrans2018.txt, only
the 4th column lon_corr_(deg) only with
0.000* shrunk to 0.*,
-0.000* to -.* and encoded in Python as a
481-tuple of 301-arrays of floats.
