Metadata for the Dataset "Baetic System Geological Map" — Version 1.0 1. General Information • Title: Baetic System Geological Map (Version 1.0) • Description:This document summarises the metadata of the geospatial dataset containingvector layers representing the geological extent of the Baetic System insouthern Spain. The dataset includes polygon features representing themountain system, tectonic discontinuities represented as line features,and a rectangular envelope polygon covering the spatial extent of theBaetic System layer. • Author: Oliver Gutiérrez Hernández (orcid.org/0000-0003-2580-5465)• Department: Department of Geography• Institution: University of Málaga• Email: olivergh@uma.es 2. Dataset Structure The dataset is organised into folders according to the coordinate referencesystem used. • 1.1_Geodata_wgs84 Contains the geospatial layers stored in the WGS84 geographic coordinate system. • 1.2_Geodata_etrs89 Contains the same geospatial layers provided in the ETRS89 coordinate reference system. Both folders contain identical geospatial layers differing only in thecoordinate reference system. Each folder includes the following layers: • Baetic_system Polygon layer representing the spatial boundaries of the Baetic System. • Tectonic_discontinuities Line layer representing major tectonic discontinuities associated with the Baetic System. • Baetic_system_envelope Rectangular polygon envelope covering the spatial extent of the Baetic System layer. Within each folder the layers are provided in two formats: • Shapefile (.shp, .dbf, .shx, .prj, etc.)• GeoPackage (.gpkg) The folder "0_Source" contains the original reference material used forthe compilation of the dataset. 3. Spatial Reference Systems The dataset is distributed using two geographic coordinate referencesystems.

Data Processing The Baetic System boundaries were extracted from the geological regionsmap of the Iberian Peninsula and the Balearic Islands from the AtlasNacional de España (Instituto Geográfico Nacional). During thedigitisation process, special care was taken to preserve the geometry ofthe original cartographic source as faithfully as possible. The Baetic System polygons were obtained by extracting the correspondinggeological region from the complete map. Unnecessary elements from theoriginal dataset were removed in order to simplify the layer and reducefile size. Only the minimum set of attribute fields required for thedataset was retained. The layer "Tectonic_discontinuities" was derived from the same geologicalreference sources and represents major tectonic discontinuitiesassociated with the Baetic System. The layer "Baetic_system_envelope" was generated using the tool"Minimum Bounding Geometry (Data Management)" in ArcGIS Pro,producing a rectangular polygon representing the spatial extentof the Baetic System layer. All digitisation, editing and geoprocessing tasks were carried outin a GIS environment. 6.1 Terminology The term "Baetic System" is used throughout this dataset to refer tothe mountain system commonly known as the Baetic or Betic Cordillera.This terminology follows the usage adopted in: Tapiador, F. J. (2020).The Geography of Spain.Springer International Publishing.https://doi.org/10.1007/978-3-030-18907-5 7.
