Copernicus initiative has boosted geospatial information services in a range of societal domains. Addressing the domain of human security we developed a validation strategy for user-specific map products. This validation strategy is based on four categories (relevance, impact, readability, transferability) that each consists of selected validation attributes. The developed expert-based scaling approach follows the Likert scale, which results in an individual grading per product. In addition to the quantitative assessment, also verbal descriptions of positive and negative aspects, as well as recommendations are provided. All validation outcomes are communicated via a web-based platform, which was developed using open-source software environments. The presentation of the validation outcomes in this intuitive manner supports the continuous improvement of the production within the service. In addition, the validation strategy is intended to be adaptive to different contexts. This assures the implementation in operational services and further application fields, where it is necessary to assure, maintain, and improve the quality of the products in the long run.
