Parse Geographic Coordinate Strings

Parse coordinate strings in various formats (MGRS, UTM/UPS, DMS, decimal) and return latitude/longitude.

geocoords_parse(x)

Arguments

x

Character vector of coordinate strings to parse

Value

Data frame with columns:

• lat - Latitude in degrees

• lon - Longitude in degrees

• zone - UTM/UPS zone number

• northp - Logical, TRUE if in northern hemisphere

• easting - UTM/UPS easting in meters

• northing - UTM/UPS northing in meters

Details

Accepts coordinates in multiple formats:

• MGRS: "33TWN0500049000"

• UTM/UPS: "33N 505000 4900000"

• DMS: "40d26'47\"N 74d0'21\"W"

• Decimal: "40.446 -74.006"
