There are two documents available for download to guide RUP users.
The first document, The Rural-Urban Projection (RUP) Program, A User's Guide, contains a complete overview of the RUP, RUPEX, RUPAGG, and RUPCombine programs.
The second file, RUPSUM2, contains a quick-reference guide to RUP data and input file format. By default, these documents are included in the USCB_Tools installation.
