Re: [Tagging] Tagging data where position is not yet known

[ralph.aytoun]

Thank you all for your responses and the positive feedback. What you have 
suggested is very helpful in accommodating this extra data rather than leaving 
it off because it does not tick all the boxes.

Again, thank you for the helpful responses.

Re: [Tagging] Tagging data where position is not yet known

Hi

I've use fixme= inaccurate location to indicate entities known to exist 
but not their exact location (say 100-200m)


Use fixme as they are flagged by OSM validators 
(https://www.keepright.at/report_map.php?zoom=14&lat=8.46549&lon=-13.20959&layers=B0T&ch=0%2C170&show_ign=1&show_tmpign=1)

Hi all,

I am looking for comments and advice regarding this.

I am working with a group of local mappers in Sierra Leone, Africa, 
under the name WAMM (West Africa Motorbike Mappers). They are trying 
to find and identify all the towns, villages, hamlets in Sierra Leone 
and have completed one whole District (Kailahun) and are well into 
their second District (Kenema). At each community they take a GPS 
reading to fix where they are (lat and long supplied) and then ask 
prominent locals (chief/headman/etc) for the name, historical name, 
any alternate names. They have also supplied other important data for 
the community such as the existence of a market and which days it is 
open, also the existence of a water pump. Unfortunately, while they 
have confirmed the existence of the latter two they have not 
identified their position.


The names of towns and villages were originally added in 2014 first by 
*rwst* with /source=GNS/ and /gns_ufi=* /and in 2014 by Pierzen_import 
adding Sierra Leone place nodes and Unocha pcodes.


WAMM have supplied a spreadsheet with the data collected and want to 
know if it can be added to OpenStreetMap. There are a lot of new names 
of smaller communities and confirmation of the names that the locals 
call their communities. This is not a problem and can be checked 
against the existing data already on OpenStreetMap.


I want to know how you feel about adding the market and water_pump 
data that does not yet exist on the map. In Africa the existence of a 
market and/or a water_pump is not only important information for the 
locals, it is important information for any medical or humanitarian 
teams carrying out any assessment or intervention in the area. I wish 
to add this data to the map near the name of the community with a 
fixme stating that the existence has been confirmed but the location 
is not yet known. The fact that it is there will be spotted by 
subsequent mappers and hopefully they will be able to move it to it’s 
correct location.


Look forward to hearing from you.

What about adding these informations right to the community nodes (like 
water_pump:present=yes and market:present=yes)? It would be precise 
information and the objects can be added later without breaking/fixing 
anything.

Not quie sure why this is on tagging, but anyway: a clear yes to adding
the data. Add a FIXME tag stating that it is a rough, village level
position for late surveyors and consumers.

Naturally you might simply be able to sit down with the contributors and
squint at aerial imagery to locate the objects post survey, given that
we slowly have a large selection of global imagery that we can use.

I'd say it depends how well you can approximate the position of these features, 
as OSM is a geo-database you'll have put things somewhere. Tagging "there's a 
waterpump and a market somewhere in Westafrica" wouldn't be very useful, would 
it?

Others before you have not been shy of doing this - some of them
deliberately, sometimes with ugly blunt imports (*cough*schools in
Mali*cough*) and others just because the imagery they had years ago was
much worse than what we had today. So, there is a lot of precedent for
that.

The fixme (something like "Approximate location, in the viccinity of
this village") is of course a must. Beyond that, my opinion is that the
approximate POI should be clustered around the place=* so that they
appear to mean "this exists somewhere in this village" instead of
having them placed at random positions around where one might think
they are actually precisely there.

you can add a water_pump tag (or pump ?) to the node/boundary
of the community
or create a node with source:localisation=etimated or unknown
or of course wait a bit until the location was found

Yes to adding the data.

While purists will want the exact location, those using the map now will 
want that indication  even if the location is off by some distance 
(possibly 200 metres?).



While the 'location is not yet known' the location will be 'near' the 
community - so it will be the best indication 'we' now have.


It may be possible to use satellite imagery to get closer .. if that is 
detailed enough and the feature is different enough to be identified.

[Tagging] Tagging data where position is not yet known

[ralph.aytoun]

Hi all,

I am looking for comments and advice regarding this.

I am working with a group of local mappers in Sierra Leone, Africa, under the 
name WAMM (West Africa Motorbike Mappers). They are trying to find and identify 
all the towns, villages, hamlets in Sierra Leone and have completed one whole 
District (Kailahun) and are well into their second District (Kenema). At each 
community they take a GPS reading to fix where they are (lat and long supplied) 
and then ask prominent locals (chief/headman/etc) for the name, historical 
name, any alternate names. They have also supplied other important data for the 
community such as the existence of a market and which days it is open, also the 
existence of a water pump. Unfortunately, while they have confirmed the 
existence of the latter two they have not identified their position.

The names of towns and villages were originally added in 2014 first by rwst 
with source=GNS and gns_ufi=* and in 2014 by Pierzen_import adding Sierra Leone
