Spatial Indexing for Effective Visualization of Vector-Based Electronic Nautical Chart

Electronic nautical chart is widely used in sailing to ensure the safety. In this paper, we focus on effective visualization of vector-based electronic nautical chart with spatial indexing enhancement. Spatial indexing has been widely used in spatial data management to improve the performance of data retrieval. Spatial indexed system electronic nautical chart is constructed with R-tree. With the electronic nautical chart visualization stack proposed in this paper, the performance of R-tree indexed system electronic nautical chart is evaluated and the result show its feasibility.
