Abstract
The wide dissemination and use of statistics about territories has induced a need for more validation and understanding about those data. We propose an interface that eases the exploration of spatio-temporal data using an interactive cartographic tool by showing data with their metadata simultaneously. This system helps to check the consistency of a set of data through the use of known and efficient methods for detecting spatio-temporal outliers. Finally, on the basis of those observations, and of their own knowledge about the data, experts can generate and export a report on data quality, conform to ISO 19115 standard for geographic metadata.
