All responsible sources may submit a capabilities statement detailing the ability of their service to meet the statement of work included with this announcement. Responses to this announcement shall only be accepted through electronic mail addressed to glewando@usgs.gov and must be uploaded and received in their entirety no later than 0900 PT June 21, 2023. Responses submitted by any other means other than stated above shall not be accepted or considered. Introduction The Grand Canyon Monitoring Research Center (GCMRC) requires analytical support to process topographic and bathymetric survey data and streamline data analysis products that advance the understanding of geomorphic processes. This project will result in the development of workflows scripts and tools that GCMRC scientists will use to make processing and analyses more efficient and repeatable. Description of Project The following tasks address high priority data processing priorities within GCMRC. Expected deliverables include the final data, summary outputs, as well as all scripts and tools developed to produce the results. GCMRC will take ownership of implementing the processing tools upon project completion. GCMRC possesses many years of high resolution topographic and bathymetric survey data for the Grand Canyon. Since approximately 1990 these channel mapping data include multi-beam and single beam bathymetric sonar data within the channel and total station topographic surveys on land. GCMRC scientists currently utilize a workflow that takes raw survey data and produces the necessary data layers required to perform channel mapping and temporal sediment change analyses. GCMRC has been using these tools successfully since the set tools that comprise the current workflow was completed in 2017. That workflow consists of a MySQL database, a set of python processing scripts, and a .NET tool for managing the database and the processing workflow. GCMRC now requires updates and modifications to these tools. The selected contractor will work with GCMRC staff and collaborators to update the current software to use the Postgres database format, execute the latest version of python, and add additional processing features. The following processing features will be added to the suite of python scripts: �Add analysis for �maximum� sandbar surface. The maximum surface will be computed for each site in the sandbar database during a model run. It is a raster surface at the specified resolution that represents the maximum elevation among all surveys in the database for that site for each grid cell. �Add functionality to have multiple stage-discharge relations for a site and apply date range for each relation to use in the sandbar analysis. �Add analysis to compute �maximum volume� and �maximum area� for each site. This is the difference between the maximum surface and minimum surface for each elevation bin. The two elevation bins for this analysis are 8,000 to 25,000 ft3/s, above 25,000 ft3/s. �Add campsite polygon analysis. The campsite polygon analysis will use the campsite polygon shapefiles to compute the area and volume of sand that is within those polygons and above the minimum surface for three specified discharge bins. Those discharge bins are 10,000 to 15,000 ft3/s, 15,000 to 25,000 ft3/s, and greater than 25,000 ft3/s. The above features will be implemented by updating the existing sandbar analysis python scripts, using the latest version of python. The existing Sandbar Workbench (.NET environment) will be updated to interact with the Postgres database and updated processing scripts. The Workbench interface will be updated to streamline data entry and execution of the python analysis scripts as follows: �Bulk data entry. Instead of inputting values for each site in the Workbench interface, input will occur using a text input file that contains all needed information (*.csv file). �Streamlined sandbar analysis run setup. Automatic selection of the set of 45 regular monitoring sites and full date range of data (first survey to most recent) for analysis run. �Separate out the execution of the �binned� and �incremental� analysis. Run the �binned� analysis only first. Run the �incremental� analysis in a separate second step. �Improve database efficiency by removing/archiving old analysis runs. �Improve raster management. (As the analysis script currently functions, each time an analysis is performed, all DEMs (tif files) for every date for each site are regenerated. While we might want to maintain some ability to force a complete re-run, it would improve efficiency to execute a run by adding only the most recent survey. The min and max surfaces could be updated by just comparing the existing min and max surfaces to the new surface. But would have to still recalculate all the volumes relative to the updated min surface.) �workbench should still be capable of exporting a SQLite database to support the web site Products The following products are expected: �Updated python scripts that perform the sandbar analysis. �Updated .Net Sandbar Workbench to run sandbar analysis and interact with sandbar database. �Rudimentary command line script to run the sandbar analysis outside the Workbench environment. �Updates to Workbench documentation covering new features. �Updates to the methods and techniques documentation covering new analysis features. Interaction with GCMRC The following items will need to be provided to the contractor by GCMRC. �GCMRC staff will provide all survey data and inputs to the multi-year survey and sandbar analyses. �GCMRC staff will work with contractor to explain the current GCMRC data processing procedures, scripts, and workflow. �GCMRC staff will work with contractor to clarify and finalize the goals of the data processing workflow. Schedule The schedule is subject to change pending completion of a final agreement. The goal is to start by mid-Summer 2023 and complete the project by the end of 2023 calendar year. This work will start with a virtual meeting with GCMRC staff. During this meeting, the selected contractor will review the current status of the sandbar data processing workflow and collaborate on finalizing the plans for the updates and modifications. A second workshop will be held once the updates and modifications are almost complete and a prototype of the updated workbench is ready for testing. This meeting will help refine the workflow, collaborate on any changes required, and also provide training on using the updated workbench. The feedback from this second workshop will then inform the remaining work to complete the project and make any modifications to the workbench software. All work will be performed remotely, with frequent progress updates. All deliverables will be provided to GCMRC within 6 months following completion of a final agreement. Copyright and Ownership Upon completion of this statement of work, all data, data products, processing scripts and other materials will be provided to GCMRC. GCMRC will retain ownership and intellectual property rights for the data and any derived data products. The contractor will make no claims to the data but may retain the right to use the skills and techniques developed during this project on other initiatives.
