en.Wedoany.com Reported - UK-based marine navigation app Savvy Navvy is expanding its coverage, adding over 2,200 US lakes and European charts for Estonia, Latvia, and Lithuania. This update covers all major lakes in Minnesota and extends to 20 other US states. The company uses an in-house method to process fragmented official hydrographic data, combined with geospatial analysis, to improve the speed and accuracy of chart coverage. Danish charts from the Danish Hydrographic Office have also been added to the app.

Elena Petru, Geospatial Data Engineer at Savvy Navvy, noted that while land mapping has benefited from decades of sustained investment, the history of hydrographic data mapping is different. The situation for inland waters is particularly fragmented, with multiple agencies potentially holding overlapping or conflicting data in various formats, lacking a single authoritative source. The company's geospatial team is addressing this fragmentation through a structured integration process.

Petru, who joined Savvy Navvy in 2023, applies her background in geoinformatics to the challenges of mapping marine and inland waters. Petru stated: "You'd be surprised how often official sources don't fully align with each other. One of the main challenges is that the same lake can be represented slightly differently depending on the dataset. The task isn't simply to pick one and apply it directly, but to carefully compare sources, understand the discrepancies, and make informed decisions on how each lake should be represented. By going beyond official sources for expert validation, we can integrate new regions faster while maintaining high data integrity, thus overcoming a major hurdle in marine navigation."

This approach has become part of Savvy Navvy's broader data processing pipeline, enabling it to expand into new areas consistently and repeatably, including waters not yet fully covered by official hydrographic surveys.

Often referred to as "Google Maps for boats," Savvy Navvy has surpassed 3 million downloads globally. The app offers smart route planning, designed to provide users with optimal routes and dynamic ETAs based on real-time data such as departure time, chart information, weather conditions, tides, vessel specifications, and local regulations.
