IJGIS_Data.zip

· Geodatabase IJGIS_FL.gdb with two features (Hospitals and ZIP_Code_Area) and table (OD_AllFlow_Time). The feature “Hospitals” contains fields OBJECTID and NUMBEDS. The feature “ZIP_Code_Area” contains fields ZONEID and Popu. The O-D travel time table “OD_AllFlow_Time” contains fields PatientZIP_ZoneID (corresponding to ZONEID in the feature ZIP_Code_Area), Hospital_ObjectID (corresponding to OBJECTID in the feature Hospitals), and Total_Minutes (travel time in minutes). All feature, table and their associated field names are self-explanatory. · ArcGIS toolkit program file Accessibility.tbx, with four associated Python scripts grouped under folder Scripts. As stated previously, this case study uses the 4th tool “Generalized 2SFCA (w External Distance Table)”, with interface shown in Figure 2. For installing or accessing an ArcGIS tool, refer to Wang (2015: 90).
