your coordinate is UTM projection (NE) so Value of 429433.02 N is metre distance from Equator to North and 1455456.46E is from left side of Zone boundary(no Zone number ).Because the value of 1455456.46E can be any zone for same latitude. You should see about UTM projection

Right you say! that’s mean value of Latitude is along the Longitude or Meridian line and value of Longitude is along the Latitude or Parallel because of Lat and Long are perpendicular each other ok!

In our model of the earth, we have 180 degrees of latitude (measuring north-south, typically written with the equator as “zero”) and 360 degrees of longitude (measuring east-west, with the “zero” line running north/south through Greenwich, England). In practice, given the circumference of the earth, that means each degree is about 60 nautical miles (which are about 15% larger than the statute miles used for the odometer of your car) at the equator. Each degree is divided into 60 minutes (so each minute is about 1 nautical mile at the equator) and each minute is divided into 60 seconds. This division allows us to state locations pretty exactly (a second is only about 100 feet at the equator).

Note that I keep writing, “at the equator”. Because we are modeling a three-dimensional, nearly spherical earth in two dimensions, the longitude lines actually converge as we approach the poles (think about drawing our geographic grid on one of those Spaldeen balls kids use for kickball). The north-south distances remain 1 nautical mile for each minute, but the east-west distances get much smaller as we go north (and south) away from the equator. Using the degrees/minutes/seconds notation allows us to ignore the fact that the distances between the longitude lines get much smaller (we can calculate the distances if we need to, but we can keep the directions consistent so that south is always south, even when the longitude lines get really close together near the poles)

if this is a real problem then just get another carpenter

These are UTM coordinates as northings and eastings, aren’t they?

“Latitude lines run east-west”
“But longitude lines run north-south.”I have a similar question from Maryland. I have a plot plan that contains reference N: 429,433.02 and E: 1,455,456.46. This is an IPF location. Any suggestions?

It’s true actually – lines of latitude do run east-west. But they measure north-south.

I’ve updated the article to clarify that concept. Thanks!

This geographic grid gives unique latitude and longitude for every position on Earth.”

the zig-zag is not the only way ton explain the locations, many locations go straight away up or down…
