Telemetry · Geospatial

End-to-end aircraft surveillance system built on a $30 USB radio receiver. Ingests live ADS-B transponder broadcasts into PostGIS, enriches each contact against a 520,000-aircraft metadata index, and runs a behavioural detection pipeline that flags low-altitude military operations, night activity, loitering patterns, and other aircraft of operational interest. Identified a cluster of low-altitude military rotorcraft over the Denver metropolitan area matching counter-drug ISR profiles, classified by platform type and operator branch through cross-referencing public ICAO hex registries with behavioural signatures.

Geospatial · Remote Sensing · Urban Forestry

Tested whether free public imagery could support urban-forestry triage in Denver's Hale neighborhood. Species-level classification of NAIP 4-band imagery against a Parks & Recreation arborist inventory reached only 17.0% across ten species — too coarse for inventory replacement. Regrouping the target into five disease-risk management classes (Emerald Ash Borer risk, Dutch Elm Disease risk, water-demanding maples, drought-tolerant conifers, other deciduous) lifted accuracy to 38.3% on 3,088 verified trees, a 2.26× improvement with McNemar p < 0.001 and non-overlapping confidence intervals. The useful product is a field-triage queue, not an automated inventory.
