Leaf morphometrics

What are the leaf area, aspect ratio, margin type and venation?

Status
Specified, unbuilt
Field
Thin — some prior work
Who wants it
Palaeoclimate, functional ecology.

Why it matters

The proportion of entire-margined species in a flora tracks mean annual temperature. Leaf shape is a palaeoclimate instrument, and every sheet is a reading.

What it needs

Organ segmentation, scale-bar calibration, and a way to handle torn leaves.

State of the art

Leaf margin analysis is decades old and done by hand. Automation is partial.
