Tabular datasets supporting LiDAR-informed modelling of megalithic landscape densities

This dataset contains the tabular data supporting the analyses presented in the accompanying article on LiDAR-informed modelling of megalithic landscape densities.

It includes results derived from two case studies, integrating megalithic site inventories (WIMD) with CORINE Land Cover data to characterise land-use contexts, spatial distributions, and density-related metrics. Separate tables are provided for each case study and data source.

The dataset is intended to ensure transparency and reproducibility of the analytical results reported in the article "Reassessing megalithic densities in Southwestern Iberia through LiDAR-based landscape analysis" and may be reused for comparative or methodological purposes in other archaeological landscape studies.

wimd_case_study_1.xlsx

Description: Tabular dataset of megalithic records from the Western Iberia Megalithic Dataset (WIMD) for Case Study 1. Each record includes a confidence score and is linked to a CORINE Land Cover (CLC) class and to a spatial grid cell used in the analysis.

Worksheet: Sheet1

Rows: 410

Fields:

• id (integer): unique identifier of the megalithic record.

• conf_score (integer): confidence score assigned to the record, reflecting identification reliability.

• country (text): country where the site is located (e.g. Spain or Portugal).

• name (text): site or element name as recorded in the inventory.

• CLC_code (integer): CORINE Land Cover level-3 code associated with the record.

• CLC_label (text): descriptive label of the CORINE Land Cover class.

• grid_id (text): identifier of the spatial grid cell used for the analysis.

wimd_case_study_2.xlsx

Description: Tabular dataset of megalithic records from the Western Iberia Megalithic Dataset (WIMD) for Case Study 2. The structure and fields are identical to those of Case Study 1, enabling direct comparison between case studies.

Worksheet: joined_layer

Rows: 178

Fields:

• id (integer): unique identifier of the megalithic record.

• conf_score (integer): confidence score assigned to the record.

• country (text): country where the site is located.

• name (text): site or element name as recorded in the inventory.

• CLC_code (integer): CORINE Land Cover level-3 code associated with the record.

• CLC_label (text): descriptive label of the CORINE Land Cover class.

• grid_id (text): identifier of the spatial grid cell used for the analysis.

corine_case_study_1.xlsx

Description: Tabular summary of CORINE Land Cover composition for Case Study 1. Each row represents a combination of a spatial analysis unit and a CORINE Land Cover class, reporting the surface area occupied by that class within the unit.

Worksheet: Sheet1

Rows: 505

Fields:

• id (integer): identifier of the spatial analysis unit (grid cell or analytical unit).

• Code_18 (integer): CORINE Land Cover code (2018 nomenclature).

• CLC_label (text): descriptive label of the CORINE Land Cover class.

• area_m2 (float): surface area, in square metres, occupied by the land-cover class within the spatial unit.

corine_case_study_2.xlsx

Description: Tabular summary of CORINE Land Cover composition for Case Study 2, equivalent in structure and semantics to the Case Study 1 file.

Worksheet: Sheet1

Rows: 512

Fields:

• id (integer): identifier of the spatial analysis unit (grid cell or analytical unit).

• Code_18 (integer): CORINE Land Cover code (2018 nomenclature).

• CLC_label (text): descriptive label of the CORINE Land Cover class.

• area_m2 (float): surface area, in square metres, occupied by the land-cover class within the spatial unit.
