Classes¶

pyunitastratigrafiche¶

No description available. A vector layer class representing stratigraphic units in archaeological contexts, backed by a corresponding database table of the same name. The class exposes a single class method, define_table, which constructs and returns a SQLAlchemy Table object bound to the provided metadata, defining columns for unit identification (gid, us_s), site information (area_s, scavo_s), stratigraphic classification (stratigraph_index_us, tipo_us_s, unita_tipo_s), survey and record metadata (rilievo_originale, disegnatore, data, tipo_doc, coord), and a MULTIPOLYGON geometry column (the_geom) via GeoAlchemy2. A unique constraint named ID_us_unico_s is enforced on the gid column.

Methods¶

define_table(cls, metadata)¶

Defines and returns a SQLAlchemy Table object named 'pyunitastratigrafiche' bound to the provided metadata, representing a vector layer of stratigraphic units in archaeological contexts. The table schema includes columns for a primary key (gid), excavation site details (area_s, scavo_s, us_s), stratigraphic classification fields (stratigraph_index_us, tipo_us_s), survey and record metadata (rilievo_originale, disegnatore, data, tipo_doc, coord, unita_tipo_s), and a MULTIPOLYGON geometry column (the_geom). A unique constraint named 'ID_us_unico_s' is applied to the gid column.
