Camera Stations

Register camera-trap deployments with active periods, compute trap-nights, and link observations to fixed stations within your projects.

A camera station represents a fixed deployment point with one or more active periods (start and end dates). Rastrum automatically computes trap-nights and lets you derive standard wildlife indices like Relative Abundance Index (RAI) and detection rate per 100 trap-nights.

Features

• Per-project stations: Each station belongs to a project. Create stations from the project UI or via the CLI with --station-key.
• Active periods: Define multiple deployment periods per station. A period with no end date means "still active".
• Automatic trap-nights: Rastrum computes trap-nights by summing the days across all active periods for the station.
• Observation linking: Observations are linked to stations explicitly — two stations within the same polygon need separate counts.
• CLI integration: The rastrum-import command accepts --station-key to assign a station during batch photo import.

Wildlife indices

With trap-nights computed, you can derive standard biodiversity monitoring metrics: RAI (detections / trap-nights × 100), per-species detection rate, and cumulative sampling effort per project. This data is compatible with CONANP and CONABIO reporting formats.
