Mapping Cross-sections
The shapefile, xsection.shp, represents the transect of each stratigraphic cross-section as a line. Each cross-section should be constructed as a single-part feature so that it has only one record in the attribute tables. The shapefile's attribute data are documented in the table below.
Attribute Table Definitions for xsection.shp
| Field Name | Type | Length | Precision | Scale | Values |
|---|---|---|---|---|---|
| ID | Text | 14 | 14 | 0 | Unique IDs for cross-sections will be in the format Xboringidfrom-boringidto. For example, a cross-section going from boring 11GD01 to boring 11GD11 would have the ID 'X11GD01-11GD11'. |
| FILE | Text | 50 | 0 | 0 | Name of the .PDF file containing the stratigraphic cross-section for this line. |
| SOURCE | Text | 60 | 0 | 0 | Project that is the source of the data. If the project has an S.P. number, enter that here. If not, use a project identifier that will be unique, such as 'Lafayette Bridge.' |
