guys...
i have been trying to plot points on a US map using latlong cordinates from 
my SQL table using virtual spatial data
ogrinfo gave the correct output..with testing2.ovf

eg:  -35.5 97.4 oklahomaq city
      -41.5 87.2 chicago
i can see the states layer but
i dont see any points on my map..from the truck layer
why? is something wrong in the projection
