GoMap Android

An experimental native Android port inspired by Go Map!!, the OpenStreetMap editor for iPhone and iPad.

Warning

This project is prerelease software. Editing is currently local and in-memory, and OpenStreetMap upload is deliberately disabled. Do not rely on it for production mapping work or expect edits to survive an app restart.

This is an independent Android port and is not an official Go Map!! release. The project preserves the upstream ISC license and attribution.

Current features

• Native Kotlin and Jetpack Compose interface backed by MapLibre Native
• Esri aerial imagery and OpenStreetMap raster styles
• Toggleable live location puck, accuracy radius, and compass-oriented bearing
• OpenStreetMap viewport downloads with styled roads, buildings, addresses, and points of interest
• Accurate node and way selection with highlighted geometry and generous touch targets
• Live whole-object dragging from the four-direction handle, including updates to connected way geometry
• Go Map-inspired selection callouts and action controls
• Go Map-inspired Settings sheet opened from the bottom-left gear
• Go Map-inspired Display sheet with four functional map backgrounds, left/right plus-button placement, and a map-rotation toggle
• Persistent foreground GPX recording with red active lines, #FE63F9 completed lines, retention settings, deletion, and Android GPX sharing
• Common Tags and All Tags editor sheets
• Offline preset catalog generated from iD Tagging Schema, Temaki, Maki, and Name Suggestion Index data
• Preset search, categories, descriptions, recent choices, and SVG icons
• In-memory undo and redo history for draft creation, geometry movement, and tag changes
• Prerelease upload control with a safety guard until authentication and conflict handling are implemented
