Description

Re: http://wiki.openstreetmap.org/wiki/Node

The above link states that co-ordinates are stored to 7 decimal places on the server. Internally JOSM handles co-ordinates to this level of precision, but only 6 decimal places are shown in the selection list and again only 6 decimal places in the Inspect / 'Advanced object info' pop-up window.

It doesn't seem right that I can zoom in and select two close nodes at two different positions but be told that they are at the same position when internally they aren't. So I think that at least the Inspect view should show the full precision, and ideally the selection format to 7 decimal places too.

The Add Node/Move Node dialog could have improved display precision also, as it currently shows zero/existing co-ordinates to 5 d.p.

The Tools > History dialog also only shows co-ordinates to 5 d.p. - when the co-ord boxes are highlighted in red to show a change the displayed values can still be identical. These should be displayed to 7 d.p. like the rest.

5 d.p. is precision of ~1 m
6 d.p. is precision of ~10 cm
7 d.p. is precision of ~1 cm

Seeing the highest OSM precision in JOSM is necessary when working with high accuracy data sources such as OS_OpenData_Boundary-Line data.
