GeoSPARQL+: Syntax, Semantics and System for Integrated Querying of Graph, Raster and Vector Data -- Technical Report
arXiv - CS - Databases Pub Date : 2020-09-10 , DOI: arxiv-2009.05032
Timo Homburg, Steffen Staab, Daniel Janke

We introduce an approach to semantically represent and query raster data in a Semantic Web graph. We extend the GeoSPARQL vocabulary and query language to support raster data as a new type of geospatial data. We define new filter functions and illustrate our approach using several use cases on real-world data sets. Finally, we describe a prototypical implementation and validate the feasibility of our approach.

GeoSPARQL+:用于图形、栅格和矢量数据集成查询的语法、语义和系统——技术报告

我们介绍了一种在语义 Web 图中语义表示和查询栅格数据的方法。我们扩展了 GeoSPARQL 词汇表和查询语言,以支持作为新型地理空间数据的栅格数据。我们定义了新的过滤器函数,并使用现实世界数据集上的几个用例来说明我们的方法。最后,我们描述了一个原型实现并验证了我们方法的可行性。
