Approximate Query Answering Based on Topological Neighborhood and Semantic Similarity in OpenStreetMap

IEEE Access, 2020
In this paper we focus on a pictorial query language, referred to as Geographical Pictorial Query Language (GeoPQL), and we revise its formal semantics by considering the polygon-polyline, polyline-polyline, and polygon-polygon topological relationships.

Multi-Parameter Estimation of Average Speed in Road Networks Using Fuzzy Control

ISPRS International Journal of Geo-Information, 2020
Average speed is crucial for calculating link travel time to find the fastest path in a road network. However, readily available data sources like OpenStreetMap (OSM) often lack information about the average speed of a road.
