Re: National Highway Mapping

Please ask user SunCobalt, what´s about his validation Tool for national roads from Poland.

http://suncobalt.dyndns.org:82/polska.php

It is wery helpful for checking of gaps and irregularities.
Maybe he can do somthing similar for national ways in India.

Re: National Highway Mapping

Hi Alok,

Well thread you have already started smile

Good to see you are actively involved in it. May be we can list down all the NH from India and track them in this thread. Do you have any other idea please do share?

One more point with NH mapping I was wondering if we could do something in maps which could shows where the conditions of roads is really bad.

Happy Mapping!!

The key to look for is called "smoothness", see http://wiki.openstreetmap.org/wiki/Key:smoothness
It is hardly used, because in the highly developed countries of Western Europe it does not add a lot of value. But with bad roads, it helps. Mappers in Romania use it for their "motorbike map", see http://wiki.openstreetmap.org/wiki/Moto … of_Romania and http://www.openmap.ro/moto/?zoom=9&lat= … s=BTFFFFTF

Re: National Highway Mapping

Dear Mr. Hiller,

Thanks for the key. This can be very useful for Indian roads. Many roads outside big cities are in very bad shape.

Shouldn't an accurate road speed index be sufficient?

Re: National Highway Mapping

Hi Sandeep,
We can add the detail of the bad road stretch, but i don't feel it will help a lot as the roads get bad in rains and get repaired later. And if we take a decision on the basis of a good or bad road status information that was updated 6 months back,,,,,then you know how big the gamble we will be taking..:)

Alternatively, i feel we can start a new thread "Latest Road Status in India",,,where users can update the status of road they recently traveled.....this way, we might even get some extensive travelers and they might help us make our road network more accurate..:)...What say??

Re: National Highway Mapping

Another Question on the nomenclature that we are following while putting "ref" for a NH/SH/MDR...!!
eg: for National Highway 1,,should we put NH1 or NH 1 or NH-1..??

Re: National Highway Mapping

Always use  NH8, SH10, MDR20  , no blanks or other seperators.

Travellers, who are OSM-mappers, can use a lot of tags like surface, smoothness width,lanes.... to describe tha staus of a highway...

I think that somebody, who doesn't map in OSM would not use this forum to post his observations.

Everybody can use openstreetbugs to report things like road status : http://openstreetbugs.schokokeks.org/

Re: National Highway Mapping

Came back from Ladakh, 2 weeks back and have logged the complete 4000 kms with 1 sec interval GPS (most of the time 15-18 satellites in rage).

Updated the Hundar-Turtuk Border road based on the detailed GPS tracks.
will update other stretches where i feel the existing tracks are way out of sync by more than 40% or so.

the NH is mappped on OSM, maybe not fully but somethings are there, it wud be nice to have a relation, so i can keep adding as i trace the NH..

Re: National Highway Mapping

Hello PowerSonic

the NH48 has a relation (958721), but there are a lot of members missing. Look at the beginning near Mangalore to Frangipete.
WIll you add the missing ways till Bangalore?

I always work with JOSM, there it is very easy to create of modify relations.

Re: National Highway Mapping

Hello PowerSonic,

I have corrected the relations: 958721 is for the NH13 (where also members are missing)
I have created a new relation for the NH48 (3185027) beginning at Mangalore with the first two ways as members.

If you have problems, I can help you to complete the relations

Re: National Highway Mapping

You are right. There are two relations for one NH. That means, the relation 958721 should be deleted and 961009 must be completed.

Some remark to NH 48 : it should be mapped with seperate ways for each direction; comparision with Bing shows, that it's not exact enough.
Motorway=yes is not correct, because this NH isn't without crossings.

i was also doing NH47 earlier..
its messed up at some part as the government has merged NH47 with NH17 and made NH66, there was already another NH66 not related to the previous mentioned, between Pondicherry - Krishnagiri

well, about NH48, its nothing I have added.. it was already existing..
I have added the new relation to the existing roads..
some parts have gps data.. well to my eyes on potlach, look exact.. potlach doesnt allow much zoom tho...
I am currently doing the editing in browser.. later at home will use JOSM..
kinda new to this so, didnt really understand why you meant its not a motorway, but will change later..

thanks..

Re: National Highway Mapping

The NH47 goes from Salem - Ernkulam-Kanyakumri;  the NH17 goes from Mumbai - Edapally (ending here in the NH47)
The NH66 is from Pondy-Krishinagiri.
In parts the NH47 is mapped as NH66, thats not OK.
Also someone has renamed the NH47 in NH544. After the proposed(?) renumbering of all NHs it may be NH544. Normally in the ref-tag the old name is used.

Motorway : I meant the motorroad-tag. Most mappers use this definition for India : http://wiki.openstreetmap.org/wiki/India:Tags/Highway

So if a trunk don't have crossings, it can be a trunk with motorroad=yes. So the NH48 is mostly only a trunk without the tag motorroad=yes.

Re: National Highway Mapping

Please could u read the Route section of this wiki page
http://en.wikipedia.org/wiki/National_H … 17_(India)
it point to a reference number 4, its a pdf, i think it has important data to be noted..

Similar info i guess, here
http://www.keralapwd.gov.in/getPage.php … pageId=301

I was amazed to see that this data belong to march 2010 and I didnt knw (I think many more ppl dont know)

as the article says, NH47 isnt in kerala anymore and NH544 and NH66 r in kerala...
Looks like OSM needs a bigger changeover now...

Re: National Highway Mapping

Yes, in the PDF (reference 4) there is a list of the renumbering of all NHs in India. But its difficult to read, because there is no table old numbers / new numbers.
Till now the mapping status is : ref-tag = old number ; ref:new-tag = new number
I propose to continue like that.
Look at the old NH47, starting at Salem : till Erode I have made yesterday a lot of corrections (including old/new ref.

Re: National Highway Mapping

but the kerala pwd link had it clearer i suppose.
thanks for guidance, i didnt understand the reference tag new and old what u mentioned, but will have a look at the corrections u did when i get the time, should make me understand better i hope.
so now what abt the old NH66 and the new NH66 clash? new relations or replace the old ones?
i feel new relations wud be better, keeping the old ones.

also could u explain what u meant by "ref-tag = old number ; ref:new-tag = new number"
