File Reference Table

File Reference Table lists the reserved filerefs for each of the different import types, a brief description of the file, and whether the fileref is required or optional when using that import type. For example, to import a Digital Line Graph file, you must allocate the file with a fileref of DLGIN.

Note:   This information can also be found in the SASHELP.GISIMP data set. See The SASHELP.GISIMP Data Set for more information.  

File Reference Table

IMP_TYPE Value	Fileref	File Description	Status
TIGER	TIGER1	TIGER basic data record	Required
	TIGER2	TIGER shape coordinate points	Required
	TIGER4	TIGER index to alternate feature names	Optional
	TIGER5	TIGER feature name list	Optional
	TIGER6	TIGER additional address and ZIP code	Optional
DYNAMAP	GDT1	Dynamap basic data record	Required
	GDT2	Dynamap shape coordinate points	Required
	GDT4	Dynamap index to alternate feature names	Optional
	GDT5	Dynamap feature name list	Optional
	GDT6	Dynamap additional address and ZIPcode data	Optional
DLG	DLGIN	Digital Line Graph file	Required
DXF	DXFIN	DXF file	Required
ARC	ARCIN	Uncompressed ARC/INFO e00 transport file	Required
MAPINFO	MIF	MapInfo Interchange Format MIF file	Required
	MID	MapInfo Interchange Format MID file	Required

For the SASGRAPH and Generic import types, which require that the spatial data be stored in a SAS data set, do not allocate a reserved fileref to indicate the location of the data set. Instead, assign the name of the SAS data set to the INFILE macro variable.
