Small-scale field mapping of lichen distribution in three dimensions with a computer-based position-tracking system

Area of Science:

• Ecology
• Geospatial Science
• Antarctic Research

Background:

• Lichen surveys in Antarctica are crucial for understanding ecosystem health.
• Traditional methods for mapping vegetation and topography are time-consuming.
• Precise spatial data is needed for accurate ecological assessments.

Purpose of the Study:

• To evaluate the efficacy of an electromagnetic position-tracking system for ecological mapping.
• To simultaneously collect topographical and lichen distribution data in an Antarctic habitat.
• To assess the time-saving potential compared to conventional survey methods.

Main Methods:

• An electromagnetic position-tracking (Tracker) system was employed.
• A small section of lichen habitat near Cape Royds, Ross Island, Antarctica was mapped.
• Data on site topography and lichen species distribution were collected simultaneously.

Main Results:

• Accurate maps and three-dimensional reconstructions of the study area were produced.
• The Tracker system facilitated the simultaneous collection of topographical and species data.
• Significant time savings were observed compared to conventional survey techniques.

Conclusions:

• Electromagnetic position-tracking offers an efficient method for mapping Antarctic lichen habitats.
• The technique enhances data collection for both topography and species distribution.
• This technology has potential for improving broader-scale ecological transect surveys.
