The goal of RDHtoLatLong is a simple way for converting "Rijksdriehoek" (RDH) coordinates to lat and long (WGS84) in R.
Coordinates in the system of the National Triangulation Survey or in short, National Triangular Coordinates (also: RD coordinates) are the coordinates in the geodetic coordinate system that is used at the national level for the European Netherlands as a basis for geographical indications and files, such as in a geographical information system (GIS). and on maps of the Land Registry and other authorities (such as: Basic map Large-scale Topography (BGT), cadastral map and topographical maps).
You can install RDHtoLatLong from github with:
# install.packages("devtools")
devtools::install_github("dosanjosfilho/RDHtoLatLong")Converting the coordinates of the city of Amsterdam in RDH to Lat Long
library(RDHtoLatLong)
x <- 121687
y <- 487484
RDHtoLatLong(x, y)
