What it is

AtlasZIM is a fully interactive offline atlas: browse the globe, switch between OpenStreetMap and satellite imagery, and search for places — all without needing connectivity.

It runs inside the Kiwix reader like an offline website, but everything is bundled into a single ZIM file.

Note: this is an offline snapshot. It does not include live traffic, routing, or frequently refreshed map data.

Quick facts

Format
ZIM file
Platform
Kiwix (desktop + mobile)
Layers
OSM tiles + satellite imagery
Search
Offline place lookup (GeoNames)

Expect to need ~25 GiB free storage (download + extraction + final ZIM).

When to use this

Use AtlasZIM when you want:

  • A fully offline world map / digital atlas experience (no network required at runtime)
  • A single-file map you can archive, copy, and share easily (.zim)
  • An offline geographic reference that runs on platforms supported by Kiwix (desktop + mobile)
  • Offline place-name lookup/search (GeoNames-backed)
  • A device with ~25 GiB free storage for the full release

Not intended for:

  • Turn-by-turn navigation, routing, or directions
  • Live traffic, real-time updates, or online map APIs
  • Scenarios where you need frequently refreshed map data (this is an offline snapshot)

What this includes

AtlasZIM is a self-contained map application bundled inside a single .zim file. When opened in Kiwix, it behaves like an offline website.

  • OpenStreetMap-based raster map tiles
  • Sentinel-2 cloudless satellite imagery
  • A Leaflet-based JavaScript map viewer
  • An offline place search UI built with Leaflet.Control.Search and GeoNames data

Why ZIM instead of traditional offline map formats?

Most offline maps are distributed as MBTiles, vector databases, or app-specific formats. This project explores a different approach: using ZIM as an offline web container.

Advantages:

  • Single-file distribution
  • Works on all platforms supported by Kiwix (desktop and mobile)
  • No dedicated map application required
  • Easy to archive and share

Features

  • Global coverage
  • Multiple zoom levels
  • Map and satellite imagery layers
  • Fully offline pan-and-zoom navigation
  • Offline place search
  • Runs entirely inside the Kiwix reader

Design decisions

This project intentionally uses pre-rendered raster tiles rather than vector tiles.

While vector tiles can significantly reduce storage requirements, they shift cost to client-side computation (geometry decoding, rendering, memory usage), which is difficult to predict across the wide range of devices that run Kiwix.

By serving simple raster tiles from a ZIM file, the map remains lightweight to render and behaves consistently even on older or low-power devices. The large file size also acts as a natural capability filter: devices that can store tens of gigabytes of tiles almost certainly have sufficient CPU and RAM to handle raster rendering smoothly.

Additionally, because a substantial portion of the dataset is satellite imagery — which is inherently raster — vector tiles would not reduce total size as dramatically in this context. The goal is maximum compatibility and predictable performance rather than minimal disk usage.

Downloads

Requirements & Installation

File size

The current version of AtlasZIM is approximately ~19 GiB. Ensure your device has sufficient free storage before downloading.

Download format

Because the file exceeds Gumroad’s 16 GiB limit, the download is provided as multiple .7z archive parts.

After downloading all parts, use 7-Zip (free, open-source) or a compatible archive tool to extract and combine them into a single .zim file.

How to use

Open the resulting .zim file with Kiwix (available for Windows, macOS, Linux, Android, iOS, Raspberry Pi, and more). The map runs entirely offline inside the Kiwix reader.

Note: Coverage extends between ±85.051129° latitude due to use of the Web Mercator projection.

Videos

(Optional later: rename the video titles on YouTube to AtlasZIM and keep “formerly Offline World Map” in the description.)
