What the free preview includes
Supported US study areas and Baden-Württemberg parcels have free browser terrain, slope, profile and possible local surface-flow indicators. CSV profile downloads remain free.
A preview access key protects a private analysis. It is not proof of purchase and does not unlock a PDF.
Check the actual report offer before purchase
PDF sales are not enabled in the established public preview. Product scope and price must be displayed before payment when a paid offer is activated.
The prepared German detail product uses a native 25 cm elevation grid and has passed bounded source and resource checks. Live sales remain disabled. There is no paid US PDF offer; the US pilot uses native 1 m elevation data where usable coverage exists.
Check the location before starting
The US pilot accepts user-drawn study areas within the contiguous-US pilot extent. The worker checks for usable native USGS project-level 1 m elevation data. Coverage is incomplete and may fail for a selected area; no coarser dataset is silently substituted.
Baden-Württemberg remains a separate established German workflow with official ALKIS parcels. US address points and drawn areas are not official parcel boundaries.
Common questions
Does this predict flooding?
No. The screening describes terrain and potential surface flow paths. It does not simulate a storm or predict water levels.
Are PDF reports free?
No. PDFs are paid products. A free preview or analysis access key is not a purchase. Check the pricing page for current sales availability.

Terrain screening provides preliminary context. Site assessment, engineering design and construction decisions require appropriately qualified professionals.
