Re: [Talk-in] Tagging VCBs

I too see it as a weir.

Tagging questions are best asked on the tagging forum rather than the 
general forum.

From what I can gather, the VCB seems to operate like a small barrage 
where shutters help raise the level of water. As a minor water 
diversion structure, it seems appropriate to tag it as a waterway=weir 
and a secondary tag like weir:type=vcb

Re: [Talk-in] old_name tag for merged Associate State Banks

[Warin]

Revert the name changesets and start again?

The new changes should then place the original name into old_name and 
introduce the new name.

Chetan, Is there any possibility to update them via script?

I am not sure if Overpass API can download based on changes in changesets.
If not, manually going through the spreadsheet would be the obvious

It would be better to write a script to query the histories of Bank 
amenity objects

and import them into JOSM and update.

Scripting would, of course, need approval from the community!

Here are my changesets: OSMCha: https://goo.gl/V76HoH

I bundled all the changes into two changesets. (There are 5 other 
singled out changesets too.)


Manually :: Downloading the changeset -> going through each object

What do you say would be a good idea?

Hi,

Back in May 2017, we have updated the name tags of merged
Associate State Banks from their old names (State Bank of xxx)
to the new name, "State Bank of India".

We have identified and tracked the entries in a spreadsheet
[1]. I have updated many entries.
However, I forgot to add the old_name tag with the old name
(State Bank of xxx) and just updated the name tag to State
Bank of India.

I think it is good to have the old names in the old_name tag
as people might still remember the banks with their old names.

Thoughts?

If the area/way can be mapped as an OSM simple single way then do that.

When the area shares ways (boundaries or sections of ways) with other 
objects then those shared ways become members of the OSM relation that 
forms the area.
This sharing reduces the quantity of OSM data and makes any edition of 
the shared boundary effect both (or in some cases more than 2, I have 
come across one with 5) areas.

Re: [Talk-in] Export Particular area

[Warin]

There are things many to think about.

Firstly OSM data is public .. if you make changes and save them to OSM 
they will be public - that is part of the conditions of OSM.


You could make changes and save them to your local storage - not to OSM 
.. that would be 'private'. However any updates to the OSM data would 
then be harder to manage as an update to your private storage. It maybe 
possible to update the data .. but I have not played with it.


Easiest would be a separate file that 'adds' to the OSM data like an 
overlay - this means you can get the latest OSM data whenever you want 
and add it with your file to produce the new 'map'.


In any event you will need to handle the .osm file which is XML format. 
The JOSM editor will do the editing/updating and saving at least for 
small areas... but all in .osm/XML.


You then have the map you want ... in .osm/XML format. What you want to 
do with it after that is then your problem. Once you have your product 
it must include the OSM copyright statement - assuming it includes OSM 
data.

Re: [Talk-in] Classification of Indian places

[Warin]

I too, have raised this same subject on the Australian list and I have 
seen it raised on the UK list with regards to Scotland.


I think the population being used to determine the OSM place 
classification works well as a first iteration.
What is being determined here is not the official, legal determination 
of a place but rather the 'importance' of a place to the locals or a 
traveller.
That 'importance' is a reflection of the services you expect to find 
there - hospital/s, doctor/s, police, shop/a diversity of shops etc.
Those services are usually directly reflected by the population, where 
it falls down is when a place is
a) remote - thus it becomes more 'important' as it is the sole source of 
services to a much larger area
b) dense - thus the population gets reduced by the neighbouring places 
'taking' some of the population as their own. And some services being in 
an adjacent place.


Some on the Australian list say that they take the services as the 
indication of the type of 'place' that it is. I think that the vast 
majority of places fit well with the population based classification 
system.
However for remote areas I think that the population required can be 
reduced in proportion to the density of the total population (over a 
very large area). This would work for the remote areas of Australia, the 
Sahara, far eastern Russia, etc
For India ... I am not local so cannot judge. But I'd try to stick with 
the population based judgement. This gets away from any political 
effects that can be had. For example Perth, Scotland was a city untill 
some acts against the crown ruler .. the crown acted by removing the 
city title from Perth.

I continue to oppose the proposal at

Hence it will make the map less useful to users. For instance the 
proposal that the classification of 'village' should be used only for 
panchayats will often promote a smaller settlement and hide larger 
settlements. There will also be a disparity in usage across the country.


There is an adequate classification at 
http://wiki.openstreetmap.org/wiki/Key:place which accords largely 
with common usage.


The government classification could however be attached to the node 
(or the boundary if available) with a specific key that reflects its 
administration status - e.g. GOIClassification=xxx.

Re: [Talk-in] Railway station GPS co-ordinates

[Warin]

Hi,
a better way ?

with this query, you immediately have a CSV file as output.

Use thishttp://overpass-turbo.eu/s/gdp

or copy the query below tohttp://overpass-turbo.eu/



[out:csv (railway,station)][timeout:25];
// gather results
(
  // query part for: “railway=station”
  node["place"="town"]({{bbox}});
  way["place"="town"]({{bbox}});
  relation["place"="town"]({{bbox}});
);
// print results
out body;


;


out skel qt;

seehttp://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Output_Format_.28out.29
for more options on the CSV output

You can make the timeout longer in case you want to cover a larger area.

Re: [Talk-in] Confusion over tagging POIs as using nodes or areas

[Warin]

Some things are better as points. man_made=water_tap would be such a 
small area that it would not be worth while mapping as an area.
Most initial mapping occurs as points - quicker and easier for the 
mapper. And it does get the information across to the end user, the 
added information of an area is helpfull but the added time of mapping 
the data compared to the benefit is not as good as that of mapping it as 
a point. If you have the time to spare than by all means map the area. 
If on the other hand you can get more information onto the map by 
mapping things as points then map as points. Greatest benefit for the 
least amount of work?

To me everything is ultimately an area (even a point, that you really

A point is thus only a convenient way of representing an area at a 
certain scale. On a world map, a city is a point, but on a city map, 
it becomes an area.


Its possible to derive a point as a centroid of an area very easily, 
but you cannot get an area from a point.


Looking at it this way, it just makes sense to map everything as an 
area whenever possible, and this makes points redundant. Hope I made 
the point clear.
