The following instructions are for participants who will use the Boundary and Annexation Survey (BAS) Partnership Tools to respond to the BAS.

These tools were developed in Python 2.7 and Modelbuilder for ArcGIS 10 or higher (not including ArcGIS Pro). They will continue to be supported at this level until the 2020 Census has occurred after which they may be adapted for other Arc products or updated for the latest version of ArcGIS Desktop.

Data Download Instructions

  1. Expand the DBAS folder and the setup subfolder. In the setup folder, find the Partnership toolbox. Expand the toolbox and double click on 1) Census Data Download.
  2. There are two ways to use this tool: one that downloads the data from the U.S. Census Bureau for the user and one that takes in a folder with the Census Bureau data already downloaded.
    • Enter the 11-digit BAS ID in the User’s BAS ID field.
    • Select Yes or No under the Use Data Downloader? field. If you select No, you must enter a path to the already downloaded partnership shapefiles in the next field.
    • If you select Yes, the data will be downloaded via the tool. Navigate or drag the folder into Path to ZIP files field. Make sure the folder only contains the Census Bureau ZIP files to ensure there are no future data issues
  3. Click OK to run.
  4. When this tool is complete, there should now be a folder for the BAS ID in the projects folder. Inside that folder, there will be a geodatabase with reference data in it and an archive folder.
