Terrain Preflight for early land due diligence

See the land before you build on it.

Your search is submitted only after you continue and is not added to the app URL.

Find a property, establish its rough boundary and inspect a factual source and area preview before payment. Custom terrain acquisition and a durable result begin only after verified Single Site or Pro access.

Terrain Preflight report

Three things to check next

  1. Review lower-bound upstream context.
  2. Confirm terrain-screen candidates with survey work.
  3. Investigate modeled flow and wet hollows.

Preliminary screening, not a survey, buildability decision or drainage design.

From boundary to decision

Site intelligence without a GIS learning curve.

01

Start with a preflight

Establish a property boundary and review elevation, slope, drainage context, modeled wetness and terrain-screen candidates without GIS setup.

02

Inspect terrain in context

Compare terrain layers, inspect profiles and review bounded watershed evidence directly on the map.

03

Take away one clear report

Download a concise Terrain Preflight report for the land-review conversation, then export KMZ, KML, GeoJSON, PNG and CSV when specialist files are useful.

Public evidence, private result

A durable terrain result that remains available.

Public terrain evidence arrives with visible source and limitations. A paid result is stored for provider-independent reopening; eligible Pro workflows can also use maintained uploads, revisions and private sharing. Review the methodology and data-source notices.
