The following information defines acceptable media for the submission of cadastral surveys in digital form. This information should be used in conjunction with the specification for digital submission of cadastral surveys.
Media
Submissions on any of the following media is acceptable:
- IBM or UNIX formatted 3.5" diskette (1.44MB DS,HD)
- HS-8mm data cartridge(2.5/5 GB, 112m)
- CD writeable (650 MB)
- ZipTM disk (100 MB)
Files requiring more than one diskette for transmission will be written to diskette for transmission using the DOS Backup utility or WinZip compression utility. DOS versions 5.0 or greater will be accepted for data transmitted utilizing the backup command. Files that are submitted in DOS backup format must have been located in the root directory when the backup command was issued. The DOS version used to create the backup will appear on the label under format. Files can also be put in a WinZip for Windows 95/98/NT (32-bit)(version 6.0 or greater) archive. No other files will exist on the media. No additional information will exist in the file aside from data being specifically transmitted to the receiving organization.
In addition receiving organizations may accept alternate media at their discretion. The primary reason for this is to enable organizations with similar systems to transfer the data more efficiently.
Unix submissions will use the CPIO utility for outputting the data. The submitter will be responsible for archival of the digital data until final acceptance.
All diskettes will be submitted with labels indicating the following data and will be signed by the licensed Land Surveyor/registered Civil Engineer submitting the map. The purpose of the signature is to verify the transmittal of the data, not professional responsibility for the data. It is understood by the receiving organization that the digital data does not constitute a professional delivery. It is the responsibility of the receiving organizations to refer to the recorded map for the correct information.
