TRAMES 1.1.2 — ground-anchored camera cones

Navigation that routes around automated licence-plate readers.

What changed

Camera field-of-view cones are now anchored to the ground. Each cone was
drawn at a fixed on-screen size, so it looked the same at every zoom and implied
a different real-world coverage each time you zoomed — and read far too small
next to the DeFlock map's cones.

A cone is now a real geographic sector: apex at the camera, swept at a fixed
radius in metres. It grows and shrinks with zoom, covers a consistent stretch of
road, and lies flat on the road when you tilt the map into 3D. The GL renderer
draws it as a filled polygon (the same primitive OsmAnd uses for eclipse
footprints); the non-GL fallback projects the same geographic sector.

Two display constants tune the look — the radius (how far down the road a reader
is shown watching) and the span (how wide the wedge is). They're a display
convention, not a survey: OpenStreetMap gives only the bearing a camera faces.

Everything from v1.1.1 carries forward.

Install

TRAMES-1.1.2-arm64-v8a.apk — 210 MB, Android 7.0+, arm64-v8a only

Verify before installing:

Package org.soulstone.trames — installs alongside OsmAnd rather than
replacing it. Open it, type a destination, and avoidance is already on.

⚠️ Read this before you trust the build

This APK is signed with the public Android debug key (CN=Android Debug,
the well-known keystores/debug.keystore, password android).

That key is not secret. Anyone can build a modified APK signed with the
identical key, and Android will accept it as an update to this app. The
signature proves nothing about who built it.

For a tool whose users are specifically trying to avoid being tracked, that is
a real weakness and not a formality. Until a proper release key exists:

  • Verify the SHA-256 above against a build you make yourself, or
  • Build from source: ./setup-resources.sh && cd client && ./trames-build.sh
