BAS Partnership Toolbox and GUPS Web demos show automated and manual change workflows

Summary
Census Bureau presenters demonstrated how to download and set up the BAS Partnership Toolbox for ArcGIS Pro, run automated creators, run attribute checks, export submission zip files for SWIM, and use GUPS Web's automated and manual editors to create, review and accept/dismiss changes before submitting to the Census Bureau.
Presenters (Speakers S3 and S4) walked through two technical toolchains for preparing BAS submissions: the BAS Partnership Toolbox (ArcGIS Pro) and GUPS Web.
Partnership Toolbox (ArcGIS Pro): a presenter demonstrated downloading "BAS Partnership Toolbox Pro," extracting the DBAS folder and using the standardized folder structure. The required first step is creating an ArcGIS Pro project named with the gov ID so the project setup tool can automatically pull the Gov ID. The setup tool downloads partnership data by county and can automatically create change files. The presenter recommended running the Attribute Check tool after making changes to surface missing or mismatched required fields and then using the Export Submission Files tool to package everything Census needs into a single zip for SWIM upload. The demo emphasized the only required legal change fields are change type, effective date, authorization type and document number (and that Georgia requires an area value for change records in that state).
GUPS Web (automated and manual workflows): a presenter showed two ways to sign up for GUPS Web and described the dashboard and help center. For automated change creation the user uploads a local shapefile or zip and selects a crosswalk field (state/place FIPS, national code, or name/legal description); the tool generates candidate changes and filters out very small 'sliver' differences. For manual change creation the presenter demonstrated drawing polygons, tracing and snapping to existing edges, selecting an action (annexation, deannexation, boundary correction), entering required legal documentation, and using the boundary review table to accept/dismiss changes before exporting. The GUPS demo also covered linear feature edits (adding roads, setting MTFCC codes and names) and user management features (inviting collaborators with roles such as viewer, collaborator, owner).
Both tool demos emphasized saving local archives of incomplete work, adding optional supporting files (parcels, centerlines, PDFs) to clarify complex changes and using the help center or geo.bas@census.gov for technical assistance.
