My “Let’s GPS Amman ourselves” post from 2005 keeps drawing the attention of some interested readers. Here is one that I thought deserved a post on it own. It’s from a “Mr Wrangler”:
How to Create Jordan Maps without Driving Around
There is a much easier way of creating maps for Amman and Jordan than driving around and taking GPS readings. Here’s how:
1.In Google Earth, zoom in to an area say, 3 Km x 3 Km.
2.Save the image.
3.Open it on Ozi Explorer as a map or any other mapping/GPS application.
4.Calibrate the map using 2 or more points that you got from an actual GPS reading on the road. Do not use the Google Earth coordinate reading since Google Earth maps are NOT geo referenced.
5.On Ozi Explorer follow the roads on the map image by marking them. Make sure to be accurate.
6.Save your marks either as a track or a route.
7.Download on your GPS and enjoy.
I created a route in my GPS from Al Waha Round About all the way to Habiba/Arab Bank branch downtown (Al Balad) and the readings were extremely close. If you calibrate your map accurately on Ozi Explorer and mark the roads very accurately you will get an accurate roadmap.
I estimate Amman to take no longer than 5 days of full time work to digitize the major and minor roads … not a very long time.
Considering how big Amman has become, I doubt it can be done in 5 days. But it’s still a cool suggestion..
I am just waiting for the day when visitors to Amman can step into their car, enter and address and get full street directions (complete with voice alerts to their destination.
