TOBIN Property Ownership and Lease Tract Arc/Info Data Distribution Tape Format
1. Distribution Media
TOBIN Property Ownership and Lease Tract data sets are available on various magnetic media and CD-ROM for mainframe, workstation, and PC based systems. Refer to product literature for availability.
2. Data Representation
No unnecessary blanks or zeros will be depicted in the data. Fields which are legitimately blank will be represented by two consecutive pipes. A blank field at the end of a table will contain only a line feed (or a line feed and carriage return for DOS machines).
Latitude/longitude coordinate locations will be carried to 6 decimal places. Latitude values in the southern hemisphere, and longitude values in the northern hemisphere, will be preceded by a negative sign. For example, the point 88.444111 west longitude and 33.555000 north latitude would be represented in a pipe file as "|33.555000|-88.444111|".
Dates will be 8-character numeric fields of the form "YYYYMMDD", where YYYY is the year, MM is the month ("01" is January, "12" is December, etc.), and DD is the day of the month from "01" to "31".
3. Arc/Info Export File Format
stctylse.e00 - Lease Tract coverage files
stctyown.e00 - Property Tract coverage files
4. ASCII Database Output
Please refer to the TOBIN Property Ownership and Lease Database Model document for specific field sizes and file relationships.
