LongLatToUTM: To convert from Geographic coordinate to UTM coordinate.

In GeodesiCL: Geometric Geodesy Functions

Description

With this function it is possible to convert from Geographic coordinate to UTM coordinate. It is also possible to convert from other coordinate reference systems by selecting their EPGS number to UTM coordinate. Review notes and references.

Usage

LongLatToUTM(longlat_df, crs = 4326, units = "m", digits = 4)

Arguments

longlat_df	Point name, Sexagesimal longitude and latitude as dataframe.
crs	EPGS number of the new coordinate reference system to transform. DEFAULT: 4326 (WGS84)
units	Select units for UTM to work. DEFAULT: 'm'
digits	Number of digits the seconds are rounded to. DEFAULT: 4

Value

a list with a data.frame and leaflet map.

Note

create data frame of epsg codes by epsg <- rgdal::make_EPSG()

Examples

# Point name
Pto <- "St1"

# Longitude
g <- -71
m <- 18
s <- 44.86475

# Value in sexagesimal
sexa_long <- sexagesimal(g, m, s)

# Latitude
g1 <- -33
m1 <- 12
s1 <- 27.11457

# Value in sexagesimal
sexa_lat <- sexagesimal(g1, m1, s1)

# Longitude and Latitude as data.frame
longlat_df <- data.frame(Pto,sexa_long,sexa_lat)

value <- LongLatToUTM(longlat_df, crs = 4326, units = 'm', digits = 4)
print(value)
