I've solved it! The biggest problem was the little difference between coordinates. As i drove with my car mapping the coordinates, the road was really up and down...and i thought, man i go very high, so this has to be seen on the program then!
After giving the coordinates in i saw nothing. I solved this using lines...so i draw each line at every point i've made and the line was long as the height!
The next problem was.. i got X Y Z coordinates.. and i used Z as the HEIGHT difference. The coordinate system of openGL uses Y axis as up and down... so i switched these and got a road from a better perspective! (the right one!) After drawing lines i got also the 3D feeling of the road.
Here the picture:
