To analyse the orthomosaic’s produced from our photogrammetry method, we are using an AI enhanced software. The software is used to identify, count and measure the size of individual corals. This allows a broad range of information about the coral community to be collected. Parameters including actual coral cover, coral growth, mortality, size class frequency, recruitment, physical damage, disease, bleaching and recovery from disturbance can be monitored.
The image below shows the annotation of a 10m orthomosaic transect. The software is used to aid in defining the outline of the corals. An identification is then assigned to each coral. The output from the software includes the identification and size of each individual coral. This information can then be used to provide a permanent record of the coral community and to assess changes over time.
The top section of the image is the 10m orthomosaic transect. The bottom section is the same transect showing the actual coral cover of the different types of corals differentiated by colour. This information is also numerically presented for further data analysis.
