Raw File Record Types
To increase our compatibility with other data collectors and desktop systems, FieldGenius uses the TDS RW5 raw file format. The raw file contains virtually all the measurements made in the field and is a complete history of what was recorded.
For more information on the raw data record format, or for additional record types, please review the Raw Data Record Specification document from Tripod Data Systems, Inc. It is available for download at www.tdsway.com
Conventional Raw Data Records
-- - Note or Comment Records
A comment in the raw file will be depicted with a record type of two dashes. Text found after the dash is the comment.
Comments are ignored during processing of the raw file and are used only for information purposes only. You can add a comment to the raw file by using the Add Comment button in the Survey Tools Menu.
