Hi,
I am new the HOT OSM as well, and am also finding line work not aligned to
imagery.
An example might be a line that has been delineated generally following the
road but plotted either side of the pixels representing the road. In such a
case, I would
initially presume that the scale at which the user delineated the road was too small.
This begs the question, is there a standard scale at which we need to interpret the imagery? Is there official documentation or a blog on guidelines on this subject?

Hi Joshua,
if you do the "fix alignment", you actually move the image, not the data. As
far as I know usually Bing is used as the reference imagery, so I would not adjust that.
If the other shapes are not aligned, the other people have probably used different
imagery and not adjusted that.
Probably there are only some shapes in the wrong place, not all? Then you can
adjust those manually or ignore them and ad your features with the default
alignment.
Experts jump in please, if I am wrong here.

Betreff: [HOT] data alignment to satellite imagery
Hi
I'm new to HOT and I'm using the iD editor.
I'm looking at an area that has shapes which do not align with the
Bing imagery. Should I use the "fix alignment" tool before I add
additional data or just add the features as they appear with the
current alignment?
Thanks
Joshua
