1. Distribution Media

TOBIN InfoBase data sets are available on various magnetic media and CD-ROM for mainframe, workstation, and DOS based systems. Refer to product literature for availability.

2. Data Representation

TOBIN InfoBase records are made up entirely of printable ASCII characters.

Numeric fields will be filled with leading zeroes if necessary.

Text fields will be blank-filled and left justified.

X-Y coordinate pairs representing locations on the surface of the earth will be 17-character numeric fields of the form "XXXxxxxxxYYyyyyyy", where XXX.xxxxxx is the longitude west, and YY.yyyyyy the latitude north. So, for example, the point 88.444111 west longitude and 33.555000 north latitude would be represented "08844411133555000".

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. Record Formats

Each record in the TOBIN InfoBase begins with two 1 character numeric fields. The first, in Column 1, is the Data Type; the second, in Column 2, is the Record Type.

These two fields act as a control for the interpretation of TOBIN InfoBase records. Each entity described in the TOBIN InfoBase consists of a sequential group of records all having the same Data Type, the entire group beginning with one record of Record Type 0.

3.1 Data Types


The Data Type field can take any value from "0" to "5", and specifies what types of entities and information are being described in the group of records. The valid Data Types are listed in the table below.

Data Type 0 Survey Data. Primarily block, township, and section boundaries.

Data Type 1 Wellspot Data. Locations of and information about wells.

Data Type 2 Abstract Data. Boundaries of and other information regarding pieces of real property. Also includes data for Bay Tracts and Junior (Conflict) Survey.

Data Type 3 Culture Data. All other geographic data available from maps.

Data Type 4 Stratigraphic Data. Stratigraphic marker (tops) information about wells.

Data Type 5 Lease Data. Boundaries of and other information regarding Leases.

Data Type 6 Tract Data. Boundaries of and other information regarding Lease Tracts

3.2 Record Types

The Record Type field can take values from "0" to "9", and specifies what kind of information is contained in the record, and the format of the information. Currently, Record Types 6 and 8 are unused, so those values are illegal. The valid Record Types are as follows.

Record Type 0 Header Record, page 1. Each entity in the TOBIN InfoBase consists of one record of Record Type 0, followed possibly by one or more other records of other Record Types. All records of Record Type 0 have similar formats, which differ slightly depending on the Data Type of the record. Some Data Types require more header information than can fit conveniently on one card. For these Data Types, Record Types 1 thru 5 are provided as a continuation of the Header. Records of Record Types 1 thru 5 have different formats depending on their Data Type. All these formats are described in detail in the sections following.
Record Type 1 Header Record, page 2.
Record Type 2 Header Record, page 3.
Record Type 3 Header Record, page 4.
Record Type 4 Header Record, page 5.
Record Type 5 Annotation Record. Writing on the map. All records of Record Type 5 have the same format, which is described in detail in the sections following.
Record Type 7 Unformatted Text Record. This Record Type allows the database to hold text fields of essentially unlimited length. All records of Record Type 7 have the same format, which is described in detail in the sections following.
Record Type 9 Latitude-Longitude Coordinate Record. Each Record of Record Type 9 can hold up to seven X-Y coordinate pairs, specifying locations on the Earth's surface to an accuracy of millionths of degrees (i.e.,six places to the right of the decimal). All records of Record Type 9 have the same format, which is described in detail in the sections following.

3.3 Survey Data (Data Type 0)

Survey Data describes the boundaries of land survey entities such as blocks (outside of Texas, townships), sections, tracts, plats, and lots. Each such entity in the TOBIN InfoBase consists of one record of Record Type 0, possibly followed by one or more Annotation Records (Record Type 5), and a sufficient number of Coordinate Records (Record Type 9) to specify the boundary of the entity.
