CPTPkarttoja

CPTPkarttoja is a community-driven project in digital cartography that focuses on producing, curating, and distributing open, interoperable map resources within a shared framework. The project aims to support education, research, and public information by providing consistent base maps, thematic layers, and tooling for creating custom maps.

Core components of CPTPkarttoja include base map tiles, vector tile datasets, style sheets, documentation, and tutorials. Assets are designed for compatibility with common web mapping and GIS platforms, and are delivered in formats such as MBTiles, GeoJSON, and Mapbox Vector Tiles. The collection emphasizes reproducibility and interoperability, enabling users to reproduce maps and workflows across different environments.

Data sources are typically public open data, government portals, and community-contributed datasets released under open licenses. The project prioritizes clear attribution, license compliance, and transparent metadata to facilitate reuse and integration with other open data initiatives.

Governance and contribution are handled by a distributed community of volunteers and partner institutions. Contributions are coordinated through a public repository and discussion channels, with a lightweight review process to maintain consistency in style, metadata, and licensing. A standard style guide and metadata schema are used to promote interoperability across tools and applications.

Impact and usage of CPTPkarttoja span education, research, urban planning pilots, and public information portals. As an open, collaborative resource, it serves as a reference for open-source cartography practices and as a foundation for new mapping projects.
