Description: Global and local path (GPP, LPP) planning is very actively researched for different vessels and manning levels. To employ planning algorithms or workflows, an environment model must be created, which is not commonly based on Electronic Navigational Chart (ENC), although it is the official and standardized representation of maritime environment. ENCs are used in Electronic Chart Display and Information System (ECDIS), a component of an Integrated Navigation System (INS), the software platform fusing ECDIS, radar, sensor data and functions including route planning for which GPP can be considered as a part thereof. ENCs were created primarily for human interpretation, however with intended usage not solely for navigation. Closed and proprietary navigational and research software, ENC format limitations, scarce availability of free ENC file formats and complex usage outside of regulated frameworks contribute to limited number of ENC based GPP research approaches, usually based on single or few ENC objects. Therefore, the purpose of this study was to create an open-source methodology based on spatially extended object-relational database, programming languages and libraries with geographic information system to manage ENC objects used for static environment modelling and GPP applicable in INS or broader context. We created the navigable area and environment model using ENC objects and hexagonal hierarchical grids from Uber’s H3 Hexagonal Hierarchical Geospatial Indexing System library. For evaluation, we used ENC objects from different usage bands and scales for area between the ports of Savannah and Charleston in the USA with results confirming the open-source methodology applicability, along with possibilities for further research and development.
