I have Need authentic map of Tehsil Rahim yar khan DIstrict Rahim yar khan Province Punjab Pakistan. I hope you will be provide me as soon as possible

Google Maps might be good for people in cities but they are rendered useless while on a highway where we go offline. Moreover, mobile phones are too small for clear vision while driving and laptops are not safe to be handled by drivers. I travel almost every month from up north to Karachi and back. The best choices I find in order of priority are units meant for cars or handheld units with reliable car mounts. I guess, for long runs, Google Maps are not a choice for me at all.

For the handheld or car mounted I am left with choices of offline maps (which can be stored in a device) from Naqsha.net and Open Street Maps.

Naqsha.net has some very good maps of our cities, highways and streets but they have a huge price tag. Moreover, the maps are not updated as often as they should be and some major important roads were missing when I traveled last month. The method of updating the users is still too primitive, one has to keep asking those guys about updates. Making and following routes in one of the major areas where major improvements are required.

The last option is to use offline Open Street Maps, but I have not tried that as yet. There are some very very easy methods to download these maps to your PC and use them in your GPS via some software like MapSource or or directly. But then again, I have had my experience with Naqsha.net and besides all the cons which I have mentioned and perhaps more which I still don’t know about, I am confident using these maps. They have brought me home so many times. I think, I would be justified in saying, “Naqsha.net has been my best co-pilot so far.”

Another choice to be considered are maps coming up from PkMaps. These guys have done some real good work voluntarily and soon they might overtake corporate sector in their professionalism. I haven’t used their maps on highways but their maps of major cities are awesome. The city details is where it leaves the Naqsha.net way behind. These maps are free of cost and extremely useful in cities, for now.

If I summarize my choices according to performance, without prejudice, the order would be:
For long routes
1. Naqsha.net (Routing might be a problem but positioning is excellent)
2. Open Street Maps
3. PkMaps
4. Google Maps (this could be on top if we had these maps offline)

For commuting in a city
1. Naqsha.net (excellent search and lots of points of interest)
2. PkMaps (where else would you find a 100% correct maps of Abbottabad)
3. Open Street Maps
3. Google Maps (this could be on top if we had these maps offline)

Despite putting Naqsha.net on top, I am not going to renew my update contract. Reason; the price. I can easily get something like that for free and there is a great chance (and potential that I see in PkMaps) that their maps might become even better with time.
