Tenningkart

Tenningkart is a term used in cartography and geographic information system (GIS) discourse to describe a modular, open-source framework for creating and rendering layered maps and geospatial analyses. It is not a single software package but a design concept that emphasizes extensibility, reproducibility, and interoperability across data sources.

Its core philosophy centers on composing maps from independent layers, such as base rasters, vector features, and thematic overlays, with a configuration-driven rendering pipeline. This allows researchers and practitioners to mix data from diverse origins while preserving provenance and versioning.

Tenningkart's development is decentralized, with implementations spread across academic projects, hobbyist communities, and open-data initiatives. As a result, there is no universal standard for file formats, styling, or workflows, though common practices include using open formats like GeoJSON and GeoTIFF, and employing modular tools for data processing and map production.

Applications include urban and environmental planning, education, and disaster response, where users benefit from transparent workflows and the ability to reproduce maps from updated data. Critics note that the lack of a canonical specification can hinder interoperability between unrelated projects.
