OpenStreetMap
I went to 'THE CITY ' Hyderabad for attending a LUG meet. The venue for the LUG meet was a IT park Ascendas which was marked in the maps. But individual buildings were not covered in OSM( google local could give more info ) . Even I didn't map as Iphone couldn't catch GPS signals in the presence of High rise buildings .
Next day my friend Kaushik came with me to a park in posh Jubilee Hills area. It is called Kasu Brahmananda park .
We were actually surprised to see peacocks in open vicinity,normally we see them under fencing in zoo . As me and Kaushik walked ahead there 2 peahens and 1 peacock marching towards us on pedestrian road . As me moved near they flew away . The flight of peacock was with a grace :)
Kaushik commented that mapping is definitely hard if you walk . Well I didnt realise that were were trying cover an area 1/3rd of Hussain sagar .
We had to search for water as our throats were burning in 45 + degrees Centigrade of heat . 
On the 2nd jogging road he started complaining and persuaded me to turn back but we somehow made it :)
And while editing I changed the park from woods to scrub and Kaushik definitely agrees with infact he says change the name to desert LOL
PS: Hyderabadi's missing the opportunity to tag this park have lot to do . One is to map the dried up lakes and the other is the jogging track outside on the border of park

Nice work! Keep on the good work!
Just two details to mention...
Some ways are very near but not connected. If you zoom in you can see it. Routing doesn't work if the ways are not connected.
imho highway=pedestrian is only used for pedestrian areas/streets in town centers (see osm.wiki/Pedestrian). In a park I use highway=track and tracktype=... (see osm.wiki/Tracktype). Maybe motor_vehicle=no if it's not allowed to go there ba car or motorbike.

For quality checking keepright is a very good tool:

osm.wiki/Keepright
On the bottom left you see how old the data is.

Adding to Zartbitter's comment: highway=track is for ways that are large enough that a 4-wheel vehicle can drive there. If it's wide enough rather use highway=footway (prepared surface) or highway=path + foot=yes (park way was "tracked" by people walking there and not by officials).
When you are using Potlatch editor you can check if a way is connected at a node if the node shows a black outline.

@zartbitter: I have a bad habit . I dont connect roads at places where I couldn't get the acurate data on the perception that unconnected roads will attract attention hence will be fixed .
As far as routing is considered . There are very very few GPS devices in India and most of them are happy using their proprietary maps . Actually very few use google maps for routing !
All the mobile phones which have GPS chip when they get released in developing world will have GPS chip missing with a slightly different model no . The reason being the mobile provider has to compete with other cheap phones .
Anyways I have connected the tracks and yeah tagged as 'track' as its most appropriate . Some times internal park authorities Jeep's roam around in the park .
