How do you find geographic coordinates?

How do you find geographic coordinates?

When outlining the coordinates of a location, the line of latitude is always given first followed by the line of longitude. Therefore, the coordinates of this location will be: 10°N latitude, 70°W longitude. The line of latitude is read as 41 degrees (41°), 24 minutes (24′), 12.2 seconds (12.2”) north.

Is WGS84 lat long?

The WGS 84 meridian of zero longitude is the IERS Reference Meridian, 5.3 arc seconds or 102 metres (335 ft) east of the Greenwich meridian at the latitude of the Royal Observatory. The WGS 84 datum surface is an oblate spheroid with equatorial radius a = 6378137 m at the equator and flattening f = 1/298.257223563.

Is Redfearn’s formula correct to project WGS84 data to northings/eastings?

It was collected using a UBLOX GPS in 2015 in Australia (Zone 55s) Would it be correct to use Redfearn’s formula to project WGS84 data to Northings/Eastings? Normally it seems that Redfearn’s formula is used with GDA94 rather than with WGS84:

What is Redfearn’s formulae?

Redfearn’s formulae Calculates ellipsoid parameters and converts UTM coords to geodetic coordinates and vice versa. Test data E,N Zne to Latitude & Longitude Latitude & Longitude to E,N,Zne Constants & Parameters

How do I convert GDA94 to grid coordinates?

Use Redfearn’s formulae to convert between geographic coordinates (GDA94, latitude and longitude) to grid coordinates (Map Grid of Australia (MGA94), eastings and northings) and vice versa. The following are available for download but are not yet available as online calculations.
