Querying Distributed GIS with GeoPQLJ based on GeoJSON

Abstract

Widespread use of the Web has increased the need to share and access distributed Geographic Information Systems (GIS). In this context, spatial query languages act as a guideline for Web-based GIS. In this paper, we focus on the Geographical Pictorial Query Language (GeoPQL) and enhance the related system in order to query distributed GIS. This is achieved by using the GeoPQLJ functions which are based on the GeoJSON format specifications. They are implemented in order to invoke the GeoPQL polygon-polyline operators, which is the focus of this paper. We define the logical diagram of the GeoPQLJ distributed system, and illustrate its underlying functionalities.
