Mapper Core (COC Base)

This upstream-faithful build adds online satellite/aerial imagery and importable imagery catalogs. It does not include Map Hub.

• macOS — Apple silicon disk image (.dmg)
• Windows x64 installer (.exe)
• Windows x64 portable build (.zip)
• Linux x86-64 portable AppImage
• Linux x86-64 Debian/Ubuntu package (.deb)
• Linux x86-64 RPM package (.rpm)
• Linux x86-64 Flatpak bundle
• Android arm64 preview (.apk)
• Release manifest (.json)

The macOS and Windows preview packages are unsigned. The macOS app is internally sealed and verified, but not Apple-notarized: Control-click Mapper, choose Open, then confirm Open. If macOS still blocks it, use System Settings > Privacy & Security > Open Anyway. In Microsoft Defender SmartScreen, select More info, then Run anyway.

The Android APK is preview-signed for direct installation rather than Play Store distribution. Uninstall an older COC preview first if Android reports a signing conflict.

1. Open Templates > Online Imagery.
2. Paste a tile URL or import the puget-sound.oic catalog.
