Calgary rivers

Authentic Alberta stream geometry. Animation follows each mapped segment; no downstream topology has been verified.

ILLUSTRATIVE WATER TEMPERATURE

Unavailable

Prototype. Water badges show a number only where a live rivers.alberta.ca reading exists (provisional, Alberta Environment and Protected Areas); other spots show no number. No observed current speed or swimming-safety data.

What this demo establishes

Moving particles follow real, attributed polyline bends. Coordinate-order animation is explicitly illustrative. Disconnected lines are never joined. Verified-direction mode suppresses all motion until a direction record is supplied.

Drag or use arrow keys to pan; + / − to zoom. Motion pauses during map gestures, while hidden, and for reduced-motion preferences. The base map is a MapTiler street map; satellite imagery is turned off.

Thermal circles are withheld because the recovered V12 circles were not clipped to water. No heat distribution is invented here.
