Why do two map vendors publish different coordinates for the same village? Latitude vs longitude: the pair students mix up most and how to keep them straight Why the same coordinates land in different places on WGS84 and NAD83 UTM zones vs latitudes and longitudes: why surveyors work in metres instead of degrees Reading coordinates off a paper topographic map with a roamer and a scale bar Latitude first or longitude first: why a swapped pair puts you in the wrong ocean How to keep a latitude column from turning into dates and scientific notation in a spreadsheet Why the same feature sits in two countries' registries with different coordinates Decimal degrees vs degrees minutes seconds: which format surveyors and hikers each prefer What the Arctic Circle and the polar zone have in common and where they differ How accurate is a phone GPS fix in a canyon of glass towers How do you read a grid reference on a national survey sheet? Geocoding vs reverse geocoding: how a street address becomes a number pair and back Why a city's official coordinates point at a city hall or a geometric centroid Why three satellites are not enough to fix your position on the ground What3words vs plain coordinates: why three-metre squares needed a proprietary word list How many decimal places in a coordinate actually matter before the extra digits are noise How do you locate a country when all you know is its latitude and longitude? How do you compare the area of a polar country with an equatorial one fairly How do you describe a location that has no address — a point in the middle of the ocean? Finding the coordinates of a place with no address: offshore platforms and desert wells
