[HOT] Tasking Manager - Overlapping Projects with the same Instructions

[Tom McDonald]

I have discovered that some geographical areas appear in more than one
project – with the *same instructions* (roads/buildings, etc). This is
resulting in some tasks being marked as Validated in one project, and yet
the same area in another project may not have this status.

Examples are http://tasks.hotosm.org/project/1018#task/1548 Validated, and
the same area http://tasks.hotosm.org/project/1043#task/89 marked as Done,
awaiting Validation.

This is happening at the edges of #1018, overlapping with at least #1043
(SoluKhumbu) and #1048 (Tanahu) – both roads, buildings, settlements,
waterways projects.

Helpfully, user ninjamask mentioned this in a task comment here
http://tasks.hotosm.org/project/1018#task/2486 18 days ago.

As Project #1018 is down to the last 10% I think someone should address
this before too much work gets wasted.

You can go to a specific task via the URL. For example:

Re: [HOT] How to fully cover a grid square.

[Tom McDonald]

Simliar to John, but at 30m. I find using a consistent zoom level helps you
notice buildings since they will be a consistent size. Thanks John for the
. I had been using mouse with constant check to the latitude ;-)

For finding buildings, I find it really useful to have a filter building=*,
with Hide, and toggle it on/off after I think I have all the buildings in a
village. Ones you have missed really show up with the rectangles gone.

Re: [HOT] Worried about task 1018

[Tom McDonald]

Though I am active, I do NOT show up on Pascal's new contributor's list
(user tmcd123, joined April 30). There must others missing as well?

Paul's suggestion "Maybe instructions should contain some images to show
clearly what is expected," is excellent. I still find it difficult to
decide what to mark as landuse=residential in rural Nepal. An example in
the documentation would be great.

Could someone please point me to a validated square that I could look at
with landuse=residential used appropriately in a rural area.

Tom
I may be new here, but I am definitely getting the hang of it. I use JOSM.

Re: [HOT] slow time mapper productivity

[Tom McDonald]

I agree John - JOSM should be encouraged for building mapping. I do not
think it deserves a difficult reputation.

An awesome and easy to use feature (besides the building tool of course) is
the filter: setting one to hide all building=* makes it really easy to flip
all buildings on/off. This makes it easier to see buildings you may have
missed.

[HOT] JOSM Banner about imagery might be misaligned?

[Tom McDonald]

Today, whenever I load Bing imagery in JOSM I get a banner at the top with
the message:

"Aerial imagery might be misaligned. Please check its offset using GPS
tracks!"


Anyone know why this is happening now and never before?

I tried IRC but no joy. I even reinstalled JOSM, tried JOSM on a new
computer, same thing.

For example, a old, validated, tile that I know was "Clean" before is
Task/square #1419 in Project #1018.

I am afraid to, and will not, do any more work until I understand what is
going on here.

Why is this happening?

Re: [HOT] Buildings outlines-multiple

[Tom McDonald]

See
https://wiki.openstreetmap.org/wiki/OSM_Tasking_Manager#Potlatch_2_-_Adding_Grid_Square

A square I edited #1419 was also impacted by your duplicate building edits,
Eleanor?. A shame to do all that work with no result!

I noticed you used Potlatch-2 so perhaps the above link is the answer. I
have not used Potlach but when I first started (with ID) I inadvertently
made edits outside the square - but caught it before saving. At least in ID
I found it easy to miss the boundary line when scrolling.

In JOSM, the squares outside your area are greyed and you cannot miss them.

Hope this helps.

[HOT] Question just to be sure.. Residential landuse areas should have at least 20 buildings?

[Tom McDonald]

I encountered a tile with many small (2 or 3 houses) areas in the hills of
Nepal marked as landuse=Residential. It is my understanding that this tag
should be used only for true "Settlements" of 20 or more houses?

I read somewhere that counting the number of "Residential" areas can be
used as a rough guide to population. This only works if they are all about
same size.

The validation instructions for my task: #1018 - Nepal Earthquake, 2015,
detailed mapping 2nd pass, states "residential/settlement areas - validate
if all settlements (a cluster of 20 or so houses) are enclosed with
landuse=residential polygon/enclosed way."

Is it correct for me to remove the landuse tag for these tiny groups of
houses?
