Description
Georeferenced database on the spatial properties of all individual shallow-water tropical coral reefs worldwide. The dataset was obtained by processing and analyzing the global-scale coral reef benthic data provided by the Allen Coral Atlas (ACA), a publicly available dataset of high-resolution satellite imagery and machine learning-based coral reef classifications.
The original data, already divided into different coral provinces, was segmented to identify the individual reefs of each province using a label assignment algorithm. This allows to analyze several spatial properties of coral reefs such as the size distribution, area-perimeter relationship, fractal dimensions and shape measures.
The dataset contains the following measures for each individual reef in each coral province:
- Area (m²)
- Perimeter (m)
- Surface fractal dimension
- Perimeter fractal dimension
- Compactness
- Diameter ratio
- Distance to nearest reef
- Longitude
- Latitude
- Geometry
