Kanalvis

Kanalvis is a term used in geographic information visualization to describe a class of visual representations of canal networks. It refers to methods and styles that emphasize navigability, infrastructure, and hydraulic context of canals within a geographic information system (GIS). Kanalvis visualizations typically combine vector maps of canal routes with attributes such as lock locations, water depth, flow direction, nearby settlements, and historical routes, to provide an at-a-glance understanding of canal systems for planners, researchers, and the public.

The term originated in European GIS communities in the early 21st century as inland waterways were mapped with greater detail and interactivity. It is not a formal standard, but a descriptive label used to describe a family of visualization practices meant to support decision making, education, and heritage interpretation.

Techniques and features commonly associated with kanalvis include layered map designs, color-coded lanes to indicate traffic capacity or canal status, variable stroke widths to reflect canal size, and interactive time controls to show how networks change over time. Data sources often include geometric canal alignments, lock and dam inventories, depth measurements, land use data, and historical maps.

Applications of kanalvis span urban planning, water management and flood risk assessment, restoration projects for historic waterways, navigation safety analysis, and tourism or educational mapping that highlights canal heritage and ecosystems.
