Preventing Floods

An effective way to prevent flooding is through effective land-use planning and detailed knowledge of land occupancy and the natural phenomena likely to affect a region. High and very-high resolution Earth observation data are valuable for producing and maintaining maps to provide information about flood-prone areas.







Assisting Risk Prevention Planning

SPOT 5 2.5m panchromatic data, which allow analysis at a scale of 1:5000, are a cost-effective solution that complements surveying methods relying on aerial photography. SPOT 5 data can be combined with cadastral maps for flood risk prevention planning. Flood prevention plans define parcel-level guidelines that serve as a basis for establishing regulatory land-use provisions and awarding building permits.
