nds-mapviewer 2026.1.4.dev53

CLI to run the NDS MapViewer Docker container for visualizing map data (NDS.Live, GeoJSON, and more)

NDS MapViewer CLI

Visualize NDS.Live, NDS.Classic, and GeoJSON map data on a deck.gl-based map with live style editing, feature inspection, and layer management — all from a single mapviewer command. No container-runtime knowledge required.

Beta — This Python package is in early development. The CLI interface may change between releases. Feedback and bug reports are welcome via the NDS developer portal.

Full documentation: https://developer.nds.live/tools/mapviewer

Features

• Map visualization powered by deck.gl via erdblick
• Multiple data formats — NDS.Live, GeoJSON, NDS.Classic (member edition)
• Live style editing — modify map styles in real time with YAML-based rules
• Feature inspection — click any map feature to explore its attributes and relations
• Local and remote data — view SmartLayer folders, FileStore files, or remote services
• Guided setup — interactive wizard for creating data source configs
• Config management — save, switch, and delete configs from the RunScreen (c)

Getting Started

The recommended way to set up your NDS.Live environment (credentials, container registry, pip index) is via ndslive-setup:

pip install ndslive-setup
ndslive-setup

This interactive wizard configures everything you need in one step, including installing nds-mapviewer.

Either Docker or Podman works as the container runtime — Podman is a free alternative if you cannot use Docker Desktop's commercial license.

Usage

mapviewer                         # HomeScreen (or auto-loads ~/.nds/config.yaml)

mapviewer /path/to/data.ndslive   # View a local FileStore
mapviewer /path/to/folder         # View a local SmartLayer folder
mapviewer /path/to/geojson/       # View a GeoJSON folder
mapviewer --demo                  # Try it with NDS Islands sample data

mapviewer mywork                  # Load a saved config by name
mapviewer /path/a.ndslive /path/b # Multiple sources at once

All commands accept -e community|member and -i VERSION.

If ~/.nds/config.yaml exists, mapviewer (with no arguments) loads it automatically and goes straight to the RunScreen.

If you edit ~/.nds/config.yaml manually, use host paths there, not container paths. The CLI translates them into the correct container mounts when it starts the container runtime.
