Package pyrdnap :: Module rdnap2018

Module rdnap2018

Main classes RDNAP2018v1 and RDNAP2018v2 follow variant 1 respectively variant 2 of the specification RDNAPTRANS(tm)2018. Each provide a forward method to convert geodetic lat-/longitudes and heights to RD coodinates and NAP heights and a reverse method for converting the other way.

The forward and reverse results of RDNAP2018v1 meet the RDNAPTRANS(tm)2018_v220627 self-validation requirements of 0.000000010 degrees and 0.0010 meter for tests inside the RD region, see Note below. Class RDNAP2018v2 does not and is not required to.

The original RDNAPTRANS(tm)2018_v220627 grid files for both variants are not included in PyPRDNAP and pyrdnap due to the size of those files. Instead, the grid files for each variant include only the lat_corr_, lon_corr_ and _NAP_quasi_geoid_height_... columns, extracted from the original grid files with leading and trailing zeros removed and formatted as row-order matrices.

Note: RDNAP2018v1, PyRDNAP and pyrdnap have not been formally validated and are not certified to carry the trademark name RDNAPTRANS(tm).
