The CPCe (Coral Point Count with Excel extensions) program is a Windows-based software (PC use only) that provides a tool for the determination of coral cover using transect photographs. A specified number of spatially random points are distributed on a transect image and the features underlying the points are user-identified. Coverage statistics are then calculated and the results sent to Excel spreadsheets automatically.
Additionally, CPCe can be used for image calibration and area analysis of benthic features. Excel sheets are automatically generated to summarize the area calculations for each image.

Allows the specification of the rectangular area of interest on the frame image. This area can be marked manually, the entire frame image can be used, x and y offsets from the image edge can be specified, or an area of specific dimensions can be marked.
Specify number of random points: Allows the specification of the number of random points drawn on the image for analysis. The points can be distributed as full random, stratified random, uniform grid, or uniform spacing.
Calculate points: Calculates the positions of the random points drawn on the image.
CPCe is released as copyrighted freeware. It is the National Coral Reef Institute's (NCRI) aim to provide a useful tool for researchers, coral reef managers, and individuals involved in coral reef monitoring, assessment, and restoration.
