TesTable and GEOQUAL are tools that evaluate the quality of passport data and geo-referencing for plant genetic resources. TesTable checks table formats for passport data and can report or correct errors. GEOQUAL assigns quality values to passport data coordinates based on parameters like coordinate accuracy, site description matching with administrative data, and environmental suitability of the collecting site. It summarizes these parameters to provide an overall quality score on a scale of 0-100. Evaluating geo-referencing quality helps ensure passport data supports the goals of conservation and use of plant genetic resources.
