Disable snap grid in high zoom

Reported by: openstreetmap@… Owned by: richard@…
Priority: minor Milestone:
Component: potlatch (flash editor) Version:
Keywords: snap grid Cc:


even when fully zoomed in, an accurate placement of nodes is impossible, because the nodes snap to an inivisible grid.

There's no grid in Potlatch (unless someone has added one without me noticing :) ), at all.

The click detection does require you to move a certain distance _or_ hold down the mouse for a certain time for it to recognise it as a drag, rather than a click.

Could you describe exactly what you're doing? Are you moving nodes, or creating new ones?

when dragging or creating a new node in highest zoom, the node snaps about 3 pixels (i just used a screen magnifier to estimate the number of pixels).
as far as i know, the resolution of the coordinates in the osm database/api should be fine enough not to cause this effect.

This appears to be a Flash Player limitation when working at this scale.

The extra zoom level has only been provided in Potlatch recently to allow access to super-high resolution Yahoo imagery in some US cities. Given the limitations of GPS resolution and imagery, and the large amount of recoding that would probably be required to fix this, this isn't a priority to fix - sorry.
