I have been analysing the pros and cons of going for a GPS survey to capture
the highway centerline data.(+/- 3m accuracy)
The project is basically to create a base map of the state highways from the
available departments maps (usually 1:50000 scale).
The next item would be to perfect the centerline data captured on the
digital maps with the information collected from the GPS survey (by driving
along the state highways with a GPS fitted vehicle).
My question is simple:
The GPS data captured will be so accurate, reflecting every small curve on
the highway again depending on the interval at which the GPS data is
captured.
How rational it would be to use/ integrate this data on a map of 1:50000
scale?
Thanks
SRG
