Find a location, draw a rough analysis area and inspect its source, size and limitations. Open the prepared result without an account. Custom terrain begins only when paid access is enabled and verified.

Terrain Preflight report

Three things to check next

  1. Review where upstream terrain extends beyond the loaded area.
  2. Confirm terrain candidates with survey and field work.
  3. Investigate modeled flow and wet hollows.

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

From boundary to decision

Answer the first terrain questions without building a GIS workflow.

01

Start with a preflight

Draw a rough analysis boundary and review elevation, slope, modeled drainage, wetness context and terrain candidates without setting up a GIS project.

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

Keep the source and limits attached to the result.

Public terrain evidence arrives with visible source and limitations. A paid result can be stored so it can reopen without contacting the source provider when paid access is enabled; eligible Pro workflows can also use maintained uploads, revisions and private sharing. Review the methodology and data-source notices.
