High quality digital site reference images are captured annually for a 1 hectare vegetation plot. The set of images for each year usually consists of twenty images: four images taken at each corner of the plot facing each of the four cardinal points, and four images taken from the centre of the plot facing each corner. The Alice Springs Mulga flux tower site was established in 2010 at Pine Hill Cattle Station, with a new core 1 ha plot established in September 2025 within the flux tower footprint.
Use Cases
- Monitor vegetation structure and layout changes over time based on annual photopoint images.
- Provide visual context for interpreting other sensor data from the flux tower site.
- Assess Mulga woodland density and cover based on the described 70-80% canopy cover.
- Track phenological and landscape changes by comparing annual image sets.
Strengths
- Images are captured annually using a standardized five point photopoint method.
- The site is part of a long-term monitoring network established in 2010.
- Images provide context for other data types collected at the site, such as hemispherical photography and phenocam images.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to a single site in Australian Mulga woodland.
