Geospatial Queries on Data Collection Using a Common Provenance Model

Lineage information is the part of metadata that describes “what”, “when”, “who”, “how”, and “where” geospatial data were generated. If it well-presented queryable, lineage becomes very useful for inferring quality, tracing error sources increasing trust in information. In addition, if a collection datasets can be related presented together, datasets, process chains, methodologies compared. This paper proposes extending step descriptions into four explicit levels abstraction (process run, tool, algorithm functionality). Including functionalities as provides high-level independent from details software used. Therefore, possible to transform initially documenting specific processing steps reusable workflow set operations chain. presents system service distributed environment. The complemented by an integrated provenance web application capable visualizing querying graph composed datasets. International Organization Standardization (ISO) 19115 standards family with World Wide Web Consortium (W3C) initiative (W3C PROV) combined order integrate To represent elements, ISO 19115-2 class names chosen, because they express objects are involved more precisely. relationship naming conventions W3C PROV used relationships among these elements. elements queryable graph.
