GeodesiCL (version 1.0.0)

geodesic: To convert from Cartesian coordinate to Geographic coordinate.

Description

With this function it is possible to convert from Cartesian coordinate to Geographic coordinate and obtain the decimal precision that you assign.

Usage

geodesic(a, XYZ_df, digits = 4)

Arguments

a

Selection of Ellipsoid.

XYZ_df

Sexagesimal longitude and latitude as dataframe.

digits

Number of digits the seconds are rounded to. DEFAULT: 4

Value

data.frame with the data in the following order: "Pt", "Lat", "Lon", "H".

Examples

# NOT RUN {
# Point name
Pto <- "St1"

# Cartesian data
X <- 1711591.78090565
Y <- -5060304.1659587
Z <- -3473256.69328603

# Pto, X, Y and Z as data.frame
XYZ_df <- as.data.frame(cbind(Pto, X, Y, Z))

# To know the ellipsoids and the order open the Ellipsoids in the package and look for it number
Ellip <- Ellipsoids
#View(Ellip)

# We choose the number 5 which is GRS80
value <- geodesic(5, XYZ_df, digits = 4)
print(value)
# }
