Syvyyslista

Syvyyslista is a Finnish term formed from syvyys (depth) and lista (list). In Finnish-language science and industry, it denotes a catalog or dataset that records depth measurements associated with geographic locations. Typical entries include coordinates and depth values, sometimes accompanied by the measurement method, timestamp, vertical datum, and quality indicators.

Such lists may arise from hydrographic surveys, sonar mapping, or bathymetric studies and are used to support the creation of bathymetric maps, seabed classification, and marine or freshwater research. They can serve as source data for nautical charts, underwater habitat analyses, or dive planning. The term is generic and can refer to project-specific data tables rather than a single standardized file type.

Data formats for syvyyslista content are commonly tabular, such as CSV or Excel spreadsheets, and may also be stored in GIS-friendly formats like GeoJSON or shapefiles. Metadata typically describes survey method, elevation reference (vertical datum), data quality, and any processing steps. In Finnish practice, a syvyyslista often functions as an intermediate or primary data product in a broader bathymetric or hydrographic workflow.

Etymology and usage notes: The word is a straightforward compound of Finnish roots for depth and list, and its meaning is dependent on context. It is not tied to a single international standard but appears in Finnish-language technical documentation, field reports, and datasets related to underwater topography.
