[Talk-in] GPS tracks galore near madanapalle

[Arun Ganesh]

Discovered a whole bunch of unmapped gps tracks near Madanapalle,
AP.
The traces are quite detailed too, although no sign of any settlement there.

So, there we are, hit 2 anomalies already. Old
NH46,NH4(Chennai-Ranipet-Krishnagiri) part of the new NH48 is actually on
east west direction but numbered as a north-south highway.They could have
made it as Chennai-Krishnagiri-Bangalore-Hassan-Mangalore as a east west
way.Probably they would have felt odd to touch golden quad.As said earlier,
they double counted Bangalore-Krishnagiri part. On the Kashmir-Kanyakumari
they have mentioned Bangalore-Salem as though they are flying over
Krishnagiri.Having a map will help us visualizing better and appreciate the
better aspects of the new numbering scheme.

Ofcourse the new numbering scheme will take some months to adjust as they
have altered highways starting from major cities and made them as part of
bigger / smaller chunks.

Should have read this first. The relevant bits:

Old - NH 1A (Srinagar-Jammu-Pathankot-Jalandhar) / NH 1 
(Jalandhar-Ambala-Delhi) / NH 2 (Delhi-Agra) / NH 3 (Agra-Gwalior) / NH 75 
(Gwalior-Datia-Jhansi) / NH 26 (Jhansi-Sagar-Lakhnadon) / NH 7 
(Lakhnadon-Nagpur-Adilabad-Hyderabad--Bengaluru-Salem-Madurai-Kanyakumari)

New - NH 44 (Srinagar-Kanyakumari) - "Kashmir to Kanyakumari" now has a road to 
its name 

Old - NH 8 (Delhi-Jaipur Byepass-Udaipur-Ahmedabad-Ankleshwar-Mumbai) / NH 4 
(Thane-Pune-Kolhapur-Hubli-Bengaluru) / NH 7 (Bengaluru-Krishnagiri) / NH 46 
(Krishnagiri-Vellore-Ranipet) / NH 4 (Ranipet-Chennai)

New - NH 48 (Delhi-Chennai)

So NH4 -- Mumbai to Chennai via Bangalore -- will now have two numbers? Because 
it runs north-south from Mumbai to Bangalore, and east-west from Bangalore to 
Chennai.

Bangalore - Krishnagiri is technically NH7, which (IIRC) runs Madurai to Delhi 
via Bangalore, Hyderabad, Nagpur and Bhopal. However, the section between 
Bangalore and Krishnagiri is a diversion from the original NH4 to Chennai.

Looks like this new scheme is going to be a mess to figure out. :-)

I would not say vandals - just an inexperienced guy with clumsy fingers. I once 
found the Kaveri flowing to the north west of Bangalore! Anyway I have updated 
the data - so Bangalore would be showing properly now. I always rm -rf the 
existing tiles on update, so it should render immediatly.

highways are major ones and 3 digit ones will be offshoots. The order of

more on the data to verify if pattern followed is uniform and truely

number of the Krishnagiri-Bangalore which forms part of both NS-corridor and
golden quad.

Thanks. So vandals have started appearing. Nice! So we have grown to reach
masses or what :)
