Usage tips


Export_arc (feature_type, in_dataset, interchange_file, compression_type, max_lines)
Parameter Explanation Datatype
Feature Type (Required)

The type of input to be converted.

Input Dataset (Required)

The input dataset.

Output Interchange File (Required)

The prefix name of the ArcInfo interchange file or files to be created by Export. A volume ID of E00 will be appended to the file name of the first interchange file, E01 to the second file, and so on. Each subsequent file is created when the {max_lines} for each file is reached.

Compression Type (Optional)

Specifies how numbers and blanks will be compressed in the export file. There are three options:

  • NONE—No compression is performed. This option can also produce an export file that can be listed on your terminal or line printer. This is the default and the preferred method for creating export files.
  • PARTIAL—Compresses blanks but does not compress numbers.
  • FULL—Compresses both blanks and numbers using ASCII compression characters. This option requires the least amount of storage space (on tape or disk).

Max Lines (Optional)

Maximum number of lines for each volume (for example, disk file) of an EXPORT file. A volume has the extension .E00 through .E99. Only one export file is created if this is not specified.
