SparQ - Spatial Reasoning done Qualitatively

A toolbox for Qualitative Spatial Reasoning in applications

Overview

• providing reference implementations for spatial calculi from the QSR community
• making specifying and integrating new calculi easy
• providing typical procedures required to apply QSR in a convenient way
• offering a uniform interface that allows straighforward switching between calculi
• being easily integrable into own applications
