Reef Chronicler · How-to

The topside procedure, step by step.

Nothing in this course is measured in the water. The numbers are made afterwards, at a table, in two Dry Sessions — and none of it needs software written for the course. Four things get done, and each has a page.

The documents hold the method; these pages hold the procedure. Menus move, buttons get renamed, and a screenshot is stale the week after it is taken. If a page here and the Course Guide ever disagree about what to do, the Guide is right. If they disagree about where the button is, these pages are the ones being kept current — and each says when it was last checked.
01 · Dry Session 1 and 2

The frame check in Fiji

Open the frame, measure the width of each of the four charts in pixels with the line tool, divide the widest by the narrowest. The ratio goes in the Entry; the smallest ratio is the frame you score.

 02 · Scoring

Point intercept in CoralNet

An account, a source, the class list, the upload, fifty random points, the buddy's independent pass, and the export that goes in the archive with the point positions.

 03 · Scoring, no account

The random-point overlay by hand

A printed transparent overlay, or a short Python script that draws the points on the frame, and a tally sheet. Slower, no version to record, cannot drift.

 04 · Scoring, offline

Fiji multi-point and Cell Counter

The offline fallback where there is no CoralNet: place the points in Fiji, count each class with the Cell Counter plugin, and save the point positions with the frame.

What none of these pages does: set a pass mark for the frame check, choose a class for a point you cannot call, or average your figure with your buddy's. Those are the course's rules, not the software's, and the lessons are where they live.
