Very High Resolution satellite imagery (eg WorldView3) provides insights into Earth surface processes, but suffers from limited spatial/spectral accuracy. While tools exist to correct these errors, there is currently no robust pipeline. Vhrharmonize is a Python library, command-line interface, and QGIS plugin that automates preprocessing and mosaic generation.

We introduce landlensdb, an open-source Python package for managing proximity sensing imagery, including action cameras, 360° cameras, and UAVs, using PostgreSQL/PostGIS. It automates metadata extraction, corrects geolocation errors via road network snapping, and enables scalable spatial-temporal queries and visualization for large-scale geotagged image datasets.

Invasive canopy-smothering vines such as Merremia peltata threaten tropical forests but are difficult to map under persistent cloud cover. This talk presents a SAR-based workflow using Sentinel-1 and open-source geospatial tools to detect and map infestation across Pacific islands, supporting reproducible, transferable monitoring for management.
