If you really need to have proper northings and eastings so that you can compare x,y locations from a paper map and a web map sharing the same projection, d3 is probably not the best vehicle for this. If you don't care about measuring the coordinates in Cartesian coordinate space, the...
The vertical lines are called eastings, with numbers increasing from left to right. The horizontal lines are northings, with numbers increasing from bottom to top. The lines are numbered along the edges of the map, and at ten grid-square intervals across the sheet. You can use these lines ...

Once the map has been projected, the Euclidean space can be mapped onto standard coordinate systems such that positions can be described by coordinates consisting of eastings and northings. Many standard coordinate systems use conformal projections, in particular the Transverse Mercator, which serves ...
The first numbers you quote are the ones that run along the bottom of the map, from left to right – the ‘Eastings’. The second block of numbers you should quote are the ones read from bottom to top, known as ‘Northings’. Four-figure grid references identify a single square on ...
Northingsare northward measured distances. They are similar to the y-axis on a graph. On a map, northings appear as horizontal lines. When writing grid references, eastings are writtenbeforenorthings. For example, we read them as 3550, 3651, 3752 and so on. ...
These are called Gridlines collectively, orEastingsfor the vertical lines andNorthingsfor the horizontal ones. On a 1:25,000 map, the distance from one side of a grid to the other (parallel) = 1km. Diagonally across a grid is 1.4kms. ...
