parzer
parses messy geographic coordinates
Docs: https://docs.ropensci.org/parzer/
You may get data from a published study or a colleague, and the coordinates may be in some messy character format that you’d like to clean up to have all decimal degree numeric data.
parzer
API:
parse_hemisphere
parse_lat
parse_llstr
parse_lon
parse_lon_lat
parse_parts_lat
parse_parts_lon
pz_d
pz_degree
pz_m
pz_minute
pz_s
pz_second
For example, parse latitude and longitude from messy character vectors.
parse_lat(c("45N54.2356", "-45.98739874", "40.123°"))
#> [1] 45.90393 -45.98740 40.12300
parse_lon(c("45W54.2356", "-45.98739874", "40.123°"))
#> [1] -45.90393 -45.98740 40.12300

sp::char2dms
: is most similar to
parzer::parse_lat
and parzer::parse_lon
.
However, with sp::char2dms
you have to specify the
termination character for each of degree, minutes and seconds.
parzer
does this for the user.biogeo::dms2dd
: very unlike functions in this package.
You must pass separate degrees, minutes, seconds and direction to
dms2dd
. No exact analog is found in parzer
,
whose main focus is parsing messy geographic coordinates in strings to a
more machine readable versionparzer
