Core Responsibilities

Primary Functions

Compile and critically evaluate a diverse range of hydrographic, topographic, and oceanographic source data, including multibeam echosounder (MBES), side-scan sonar, Lidar, and satellite-derived bathymetry.
Author, update, and maintain official nautical charts in both digital (Electronic Navigational Charts - ENC) and raster/paper formats to ensure they are fit for the purpose of safe navigation.
Perform rigorous quality control and assurance checks on geospatial data and cartographic products to verify compliance with international (IHO S-57/S-100 series) and national cartographic standards.
Apply advanced cartographic principles, including symbolization, generalization, and feature selection, to ensure chart clarity and prevent information overload.
Process and apply critical safety updates, such as Notice to Mariners (NTMs), to all relevant navigational products in a timely and accurate manner.
Manage and maintain the integrity of large-scale hydrographic and cartographic databases, ensuring data lineage, metadata, and versioning are meticulously documented.
Create high-resolution digital bathymetric models, gridded surfaces, and contours from processed survey data for charting and scientific analysis.
Collaborate directly with hydrographic surveyors and data processors to understand data limitations, resolve ambiguities, and ensure a seamless flow of information from field to chart.
Research, assess, and integrate new or non-traditional data sources, such as crowdsourced bathymetry and satellite imagery, to enhance chart coverage and accuracy.
Perform complex geodetic computations, datum transformations, and projection conversions to ensure all data aligns within a common, reliable spatial framework.
Analyze and resolve complex cartographic compilation issues, such as feature conflict, data gaps, and depiction of intricate maritime features like traffic separation schemes and anchorage areas.
Generate and validate shoreline data from various sources, including aerial photography, satellite imagery, and Lidar, to accurately depict the land-sea interface.
Develop and maintain technical documentation, standard operating procedures (SOPs), and workflow diagrams for cartographic production processes.
Utilize scripting languages, primarily Python, to automate repetitive data processing and cartographic tasks, improving efficiency and consistency.
Create specialized thematic maps and custom charting products for a variety of stakeholders, including coastal zone managers, marine biologists, and port authorities.
Participate in the validation and testing of new cartographic software, production systems, and evolving data standards like the IHO S-100 Universal Hydrographic Data Model.
Liaise with external maritime authorities, stakeholders, and the public to address chart-related inquiries and provide expert guidance.
Interpret and compile man-made and natural features from source materials, ensuring accurate attribution and representation on the final product.
Manage chart schemas, feature catalogues, and symbol libraries to maintain consistency across the entire suite of navigational products.
Provide cartographic expertise and support for maritime boundary delimitation and other marine spatial planning initiatives.
Conduct thorough historical chart and source analysis to inform compilation decisions and resolve data discrepancies over time.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis for internal and external stakeholders.
Contribute to the organization's broader data strategy and the roadmap for transitioning to next-generation S-100 products.
Collaborate with business units and hydrographic planners to translate navigational needs and safety requirements into cartographic specifications.
Participate in sprint planning, retrospectives, and other agile ceremonies as part of a collaborative production team.
Mentor and provide technical guidance to junior cartographers, interns, and GIS technicians.
