Communities · Who and What Is Exposed?

Dependency design · not executable yetExposure requires vetted population or building nouns and a coherent hazard/history noun; those public interfaces are not available.

The decision

Which South Dakota communities or built areas occur in landscapes with a documented environmental hazard history or clearly measured changing condition?

A Rapid City/Black Hills fire-history story is a plausible candidate, but it will not be selected until structure coverage and event-perimeter sources are validated together.

The missing information

An environmental layer becomes more decision-relevant when the people or assets potentially exposed are represented. Historical intersection can describe past spatial context; it cannot by itself estimate future risk.

The nouns

Noun	Public status	Publication requirement
Population	Missing	Census vintage, unit, allocation method, uncertainty
Buildings	Missing	Footprint/count completeness, date, use limitations
Fire history	Missing	Event dates, perimeter quality, duplicate handling
Temperature or VPD	Implemented	Weather context only; not a hazard model
Roads	Missing	Network completeness and scale

The analytical sentence

Target grammar only:

BUILT AREAS → OVERLAP DOCUMENTED FIRE HISTORY → SUMMARIZE HISTORICAL EXPOSURE CONTEXT

The final noun and terminology must match. Buildings support statements about mapped structures; population supports statements about resident counts only under the source's allocation assumptions.

What happened?

Nothing has been calculated. Using public temperature or VPD alone would not preserve the question because neither identifies communities or establishes a wildfire hazard layer.

QA publication gate

Required visible checks include structure/population coverage, event dates and perimeters, CRS and boundary alignment, temporal compatibility, duplicate counts, missing areas, and a direct comparison of each noun before overlap.

Decision view

Unavailable. When implemented, the result should say “structures occurring in landscapes with documented wildfire history” unless a validated forward hazard model supports stronger language.

What this does and does not tell us

The analysis could guide where to seek more detailed preparedness or asset data. Historical overlap is not a probability forecast, vulnerability assessment, or estimate of future loss.

• Replace fire history with a defensibly measured heat condition.
• Compare buildings with population without treating them as interchangeable.
• Change the time period and state exactly what temporal claim changes.
