Updates on image correction.

Posted by brian_bancroft on 5 January 2020 in English.

I am especially not good at dealing with image offsets.

My challenge is finding a close-enough to truth for certain locations. In absence of proper markers, what I will be using for reference consists now of the following:

  1. The roundabout.
  2. The lanes of the Trans-Canada highway as they meet Roberts.

For Bing imagery, this gives me an offset of 1.61, 1.53

You can also look at User Traces. If there are enough of them you can be more precise.

There’s also Strava heatmap imagery which is more likely to be there than OSM user traces.

@units, @GinaroZ, thanks for your input.

I guess this means that I’m going to have to leave the friendly UI of ID for JOSM. Thanks!

So @units, there’s a few traces in the downtown area. It’s not much, but it gives me an idea there. Thanks again!

Not really, I use the Strava heatmap as a custom background layer in iD and switch between the layers (ctrl + B). Much quicker than opening JOSM.
