论文摘要
我们在语义Web图中介绍了一种语义表示和查询栅格数据的方法。我们扩展了GeoSparql词汇和查询语言,以支持栅格数据作为一种新型的地理空间数据。我们在现实世界数据集中使用多个用例来定义新的过滤器功能,并说明我们的方法。最后,我们描述了一种典型的实施,并验证了我们方法的可行性。
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.
