About this opportunity
The U.S. Geological Survey is conducting market research to identify qualified vendors to provide expert-level Python and PINGMapper custom programming services, with responses due May 26, 2026 at 0900 hours Eastern Time. This sources sought announcement carries no set-aside. The CWSC requires modification of open-source PINGMapper source code to assess benthic substrate conditions and sediment fate following 2023–2024 dam removals on the Klamath River, California, where approximately 1.2 million metric tons of fine-grained sediments were released downstream.
Work encompasses five tasks over a one-year performance period: implementing confidence thresholds for substrate class optimization (three months); integrating auxiliary high-resolution GNSS data into PINGMapper workflows (five months); batch-processing 75 sonar survey sites across 120 river kilometers to produce georeferenced mosaics and substrate maps (seven months); conducting reach-level change detection analysis with QA/QC validation (eight months); and delivering a USGS-ready data release package with accuracy assessment and manuscript supporting information (eleven months). All work shall be performed at the contractor's facility. USGS will provide all raw sonar recordings and auxiliary GPS data. All deliverables, including source code enhancements and processed analyses, become USGS property, with source code modifications to remain open-source under the existing license.
NAICS 541511 applies; the size standard is $34 million. Responses limited to 10 pages shall be submitted by email only to Joahnne_Ongjoco@ios.doi.gov. This announcement is for planning purposes only and does not commit the Government to award.
