What is structure separation distance?
The horizontal spacing between structures or major combustible exposures considered when evaluating structure-to-structure fire spread.
For Tecnobosque, structure separation distance is useful only when its source, spatial context and observation or modelling window are stated. The same label can otherwise hide important differences between field observations, remote sensing, forecasts and reconstructed incident evidence.
Why it matters
Structure Separation Distance is useful because it separates one specific part of wildfire behaviour, exposure, operations or evidence from nearby concepts that can otherwise be mixed together.

What changes structure separation distance?
Field observation, remote sensing, model output and retrospective reconstruction can produce values with different assumptions and uncertainty.
A point, parcel, fire-front segment, incident perimeter and regional product can represent very different physical scales.
Wildfire conditions evolve rapidly, so timestamps and averaging periods are part of the meaning of the value.
How to interpret structure separation distance
- Identify exactly what object or process the value describes.
- Check units, spatial scale, timestamp and source before comparing values.
- Separate direct observations from modelled or reconstructed estimates.
- Preserve uncertainty and later revisions instead of overwriting earlier evidence.
What structure separation distance cannot tell you by itself
- Structure Separation Distance is not a complete description of wildfire hazard or risk by itself.
- Values from different methods or scales may not be directly comparable.
- A technically precise number can still be misleading when context or uncertainty is omitted.
Structure Separation Distance FAQ
Is structure separation distance one fixed value for an entire wildfire?
Usually not. Wildfire conditions vary in space and time, so the value should be attached to a defined place, object and observation period.
Can structure separation distance be used alone for an emergency decision?
No. Operational decisions require current local authority information and a wider set of conditions than a single technical concept can provide.
