P. Waddell, 2010OPUS Data• Where do the OPUS Data actually reside on the computer?- The default location is under opus/data, but if you chose a different location for it, itwould be the path that is in the environment variable OPUS_DATA_PATH- Under the main data directory are project directories. The installation comes withtwo sample projects (and more may be added soon):• eugene_gridcell• seattle_parcel- These directory names should match the project name in a project xml file- Under each of these directories, in normal use there will be 3 subdirectories:• base_year_data: this contains a year subdirectory and under that, directories for each dataset• runs: this may not exist until a scenario has been run, but then contains a subdirectory for each run• shapefiles: this directory is a special one for creating a modified ESRI shapefile for use in mapping indicators• A reminder: all the files in the dataset directories are actually individual Numpyarrays, but OPUS ‘knows’ how to load them as needed and treat them as tablesThursday, September 16, 2010
P. Waddell, 2010UrbanSim Base Year Data• In order to have a working UrbanSim model application, a Base Year Databasemust be developed. The sample projects are ones for which this process hasalready been completed, and copied to the OPUS data format (Numpy arrays)• The development of the base year database is covered in a separatepresentation.• The process of moving the data from a database (SQL) environment to theOPUS data format is referred to as ‘caching’ the database. The OPUS datastorage on disk is also sometimes referred to as the ‘cache’.Thursday, September 16, 2010
