Hi,
I wonder if a kind of FAQ about aerial imagery interpretation wouldn't
be something useful too.
Mapping in Africa (not that often) on HOT tasks, I was faced more than
often with features in the imagery that I couldn't understand.
That being said, taking a screen-shot then upload it on a wiki is not
likely something to happen often while mapping without a more or less
automatic tool to do it.

Hi,
I think there is a gap between the training available from the various
sources such as LearnOSM & someone reaching the stage of feeling
confident to map for HOT. Although we tend to think of new mappers
with no experience at all, it also extends to mappers who are used to
mapping their 'own back yard' but are concerned they may not interpret
the aerial imagery correctly when mapping for HOT.
I have seen several messages appear on the HOT mailing list where a
'new to HOT' mapper has asked where to start. I've also been contacted
by a number of mappers asking me to check / validate their first
squares in HOT. Having been involved in training new mappers at
mapathons I have noticed they are unlikely to finish the current size
of squares within 2 hours & they are also interested in receiving
feedback on their progress. Recent discussion on this mailing list
indicates many mappers are interested in feedback, especially in the
early stages.
As a test to see how successful it would be, I'm interested in having
a project / Task which is marked up as suitable for new mappers. The
squares should be much smaller in size, such that we anticipate the
new mapper can complete a square within 15 to 20 minutes. In the
perfect world that square would then be looked at fairly soon by a
validator who makes suggestions if they are needed. After completing a
few of these squares the new mapper should have the confidence to move
onto any of the other general tasks. As an aside, this need not be a
'new task' - it could just as easily be a 'high' which has dropped
down the list, but it would need adapting with additional
instructions, and exisitng squares awaiting validation being validated
& the outstanding squares being split far smaller than normal. It
would need to be advertised so that new mappers find it - highlighted
link from the home page of the Tasking Manager?
I'm willing to validate & offer feedback on such a project / task, but
ideally several other validators need to be involved. There are also
times when I am not available.
These views are my own - it would be good to get the opinions of;
a/. New to HOT mappers (we all were once, so everyone's view
appreciated) - would it have helped with the transition, and
b/. potential validators for such a project / task. - if there were a
few squares waiting validation (potentially a new mapper waiting for a
progress report before continuing), would you be willing to help with
the validation. Because the squares are smaller there will be problems
with working out highway grades, and an overview approach viewing
several squares on occasion would be needed.
I'm intending to present this topic at a Training working group, but
would like the views of other mappers.
