Blake,
How does one change the alignment of imagery with ID? I've been
mapping with ID for over a year, and I never heard of that.
This is just what Laura is talking
about. We need plain and simple guidance.
When both the Bing and Worldview imagery
were available in Mali, I used
only the Bing imagery, because it was clearly superior (no huge pixels), and I
moved objects as necessary to align with Bing.

This applies to ID and JOSM. The task will load WorldView imagery
for either editor. I think you have the directions basically correct,
but as I read them now my understanding is this:
1. Start editing a task.
2. Load the Bing imagery (now 2013 images). (In JOSM do not use the
alignment database plugin settings, they are no long needed for Bing imagery)
3. Make sure some buildings and roads are mapped correctly using the Bing
imagery. Move or map some new ones to match Bing.
4. Then load the WorldView imagery (2014 imagery).
5. Background align the WorldView imagery to match what you just mapped
in using the Bing imagery if needed.
6. Carry on mapping using the WorldView imagery after you have aligned
it or checked its alignment.
Discussion: Just make sure you use the Bing imagery as the reference. So
you would not do any background image alignment with the Bing imagery.
If buildings or roads were not well matched to the Bing imagery you could
redraw them to match the Bing imagery. Once you have drawn some buildings
and roads using the Bing imagery, you would then display the WorldView
imagery and do the background image alignment to make the WorldView
imagery match up with what you drew using the Bing imagery if that is needed.
That process is what it means to use the Bing
imagery as the reference imagery:
You map some with Bing, then align any other imagery to what you mapped using
the Bing imagery.

assuming all activations are for the general
public to contribute to? The "whys and
wherefores" and technical information I feel are
often getting in the way of plain
and simple guidance as to what is required, so
people can just get on with it, and not
have to hunt for the pertinent
information. Plainly worded bullet points would be ideal.
Any "nice to know" information could be provided below this.
You are right on each point here. It is a
challenge though with many different people
creating directions for Projects. It is too easy
to forget not everyone knows what
"vector data" is. And there is the issue that
not everyone is a native speaker of the
language the directions might be written in. We
are working to create some standard
sets of directions in English for things like
drawing buildings and roads, aligning
imagery, etc that a Project creator could ,
optionally, choose to use. That will help
with some of the inconsistent directions.
Thank you very much for helping map and please
let us know if you have any further
questions.
cheers,
Blake
