National Highway Mapping

Dear Moderator,

I feel we should start a new thread of NH mapping in India…!!

I have done and validated the mapping for NH79 till Indore and NH 3 from Indore to Agra…!! had done many NH in parts,can check back and update on the latest state…!!

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.

Hi Alok,

Well thread you have already started :slight_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/Motorcycle_map_of_Romania and http://www.openmap.ro/moto/?zoom=9&lat=46.17031&lon=23.30633&layers=BTFFFFTF

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?

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…:slight_smile:

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??

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…??

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/

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.

Added/updated the roads from NH1d till Kupwara in J&K…All other roads seems to be pretty accurate and matching with GPS track…!!

is there a place with list of NH and their mapping progress?
and is there a source for NH numbering?

NHs in OSM : Look here : http://wiki.openstreetmap.org/wiki/WikiProject_India/National_Highway_Network

thanx Heinz_V… how do we add a new relation for the NH…
for eg NH48 doesnt have a relation and a page… how can we add one, so can u do it?
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…

Thank you… :slight_smile:

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.

Bye

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

Heinz_V

thanks, then isnt 961009 also for NH13?
961009 has some members that 958721 doesnt…

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.
