Dear all
Could someone inform me of the vertical accuracy of global positioning
systems (GPS).
I am particularly interested to hear from anyone who has experience using
GPS in situations in informal settlements in developing countries where this
is almost always a complete lack of any form of data.
In these situations, I would imagine that GPS would be very useful, but I
was wondering if hand-held GPS provide sufficient accuracy for the purpose
of topographical surveying with a view to urban drainage system design.
