[Talk-in] Taginfo for India OSM

[Yogesh योगि]

Hi Naveen,

To get the length of roads in OSM, tools like road_length 
<https://github.com/yogiks/osmium-contrib/tree/master/road_length> and 
osm-length 
<http://svn.openstreetmap.org/applications/utils/filter/osm-length/> can 
be helpful(Anyone else know other programs?). Other way of doing 
this(I've never tried) can be loading osm2pgsql database with 
geofabrik's India OSM extract and running required queries.

Tried Frederik's osm-length-2.pl 
<http://svn.openstreetmap.org/applications/utils/filter/osm-length/osm-length-2.pl> 
with Bengaluru 
<https://s3.amazonaws.com/metro-extracts.mapzen.com/bengaluru_india.osm.bz2> 
OSM extract and got the following result -
$perl osm-length-2.pl blr.osm > blrroads.osm
highway length sums (metres):
                  6033537m
residential      5054166m
unclassified     2923566m
tertiary         1570188m
secondary         671660m
service           593373m
primary           482729m
track             405331m
trunk             329030m
motorwa y         122168m
living_stre et    107621m
footway            86635m
road               31193m
path               27774m
primary_link       21972m
motorway_link      21734m
trunk_link         20323m
pedestrian         17188m
construction       12494m
tertiary_link      10146m
secondary_link      5783m
steps               2086m
raceway              807m
proposed             265m
bridleway            184m
cycleway              76m
TOTAL           18552043m


As per the tagging scheme 
<http://wiki.openstreetmap.org/wiki/India:Tags/Highway#Major_Roads> , 
most of the NH except few Urban Arterial Roads are tagged as 
highway=trunk <http://taginfo.openstreetmap.in/tags/highway=trunk#map>. 
So length of trunk can approximately tell the NH coverage in OSM.


cheers,
yogi
