Shapefileban

Shapefileban is a term used in GIS policy discourse to describe policies that prohibit the use, distribution, or exchange of ESRI Shapefile data formats in certain contexts. The term is not an official standard but a shorthand for evolving governance practices that favor modern, open, or more robust geospatial data formats.

Origins: The concept emerged as organizations faced limitations of the Shapefile format (separate files, limited attribute support, coordinate precision, licensing constraints) and as concerns about data interoperability and security grew. Proponents argue alternatives such as GeoPackage, GeoJSON, or Parquet with spatial extensions provide unified, robust, and open ecosystems.

Mechanisms: Shapefileban is implemented through procurement policy, data-sharing agreements, portal upload restrictions, or licensing terms that exclude .shp/.shx/.dbf sets; in practice, data catalogs may require conversion upon submission; tooling and pipelines are updated to read and convert to preferred formats.

Impact: Policy makers say it improves data interoperability and future-proofing; critics warn of burdens on legacy datasets and potential data loss or vendor lock-in. Debates focus on transition costs, standards momentum, and whether bans are the best approach compared to requiring open formats or providing format-agnostic ingestion.
