Land Suitability for Lettuce Cultivation in Nariño Department, Colombia

A land suitability map for commercial lettuce cultivation in the Nariño Department of Colombia, produced in December 2018. The dataset results from a land evaluation methodology applied at a 1:100,000 scale, incorporating biophysical, socioeconomic, and socio-ecosystem components. It was developed under contract 222 of 2017 between UPRA and the University of Nariño.

Use Cases

• Classifying land aptitude for lettuce using the Aptitud column on a polygon-by-polygon basis.
• Calculating total suitable area in hectares for different aptitude classes using the Área (ha) column.
• Mapping and visualizing suitability zones by joining the Aptitud categories to the geographic polygons in the_geom.
• Identifying and filtering out legally excluded zones for agricultural planning using the Aptitud categories.

Strengths

• Includes multiple suitability categories (Alta, Media, Baja, No Apta, Exclusiones legales) for detailed analysis.
• Contains a geographic geometry column (the_geom) enabling spatial visualization and analysis.
• Provides area calculations in hectares (Área (ha)) for each classified polygon.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
