Very near-term prime-time technology. Successfully demonstrated in multiple states. Promises to help bring meaningful streamlining to various NEPA processes. Helps preserve the intent of NEPA to consider all alternatives. Needs to be pilot deployed and applications taken to production mode to allow delivery of finished information products rather than raw data.
