Large-scale maps use a larger representative fraction and show local areas in greater detail.

Satellite and airborne sensors record reflected or emitted energy for mapping and analysis.

Water and sediment move through connected drainage systems, linking upstream and downstream decisions.

The passage recognises possible gains while retaining uncertainty, limits and the need for further evidence.

The text identifies group, maintenance, design or contextual factors, so a careful inference is that implementation conditions matter.
