D--SATELLITE SHORELINE PROCESSING SYS.

The USGS is seeking a small‑business firm to design, develop, and deliver a Satellite Shoreline Processing System (SSPS) that automates regional‑scale shoreline extraction from satellite imagery, validates results, and releases the code under an open‑source license. The effort is a firm‑fixed‑price, six‑CLIN contract spanning roughly 20 months, with all work performed remotely using USGS Advanced Research Computing resources; the government will supply laptops, PIV cards, and training data. Deliverables include a strategic plan, prototype code, enhanced code, validation report, code publication, and a virtual training session. • Develop and deploy a CoastSeg‑based software pipeline for ≥ 50 km U.S. coastline processing. • Provide validation against USGS‑provided reference datasets and deliver a technical report before May 31 2028. • Release all source code to an official USGS repository under GPL‑3.0, accompanied by an Accessibility Conformance Report (VPAT 2.1).
