The clearest hot zones sit in the more urbanized eastern and central portions of Fairfax County, while the western side stays cooler where vegetation cover is stronger and development density is lower. Heat patterns are shaped by several land-cover and built-environment factors, not a single driver.
Immediate shock (2004–2005): electricity access dropped 4.2 points, industrial CO2 intensity collapsed 76%, unemployment jumped 2.6 points, industrial production growth halved. National-level recovery was largely complete within two to three years.
Open-core engine. Maintained pack layer.
The engine and schemas are open source. What you pay for is the maintained path: processed datasets, source-backed releases, versioned packs, freshness, packaging, and support. That maintained layer keeps every surface aligned on one published truth.
