EarthTrack vs LicheN

EarthTrack has been developed to facilitate ground-level collection of land cover, habitats and change to support routine and continuous characterisation, mapping and monitoring of landscapes from Earth Observation (EO) data as well as assist future co-designed planning. EarthTrack is a component of the Living Earth system, that constructs past, current and future land cover maps from environmental descriptors retrieved from Earth observation data or predicted (e.g., through modelling). Examples are vegetation canopy cover (%) and height (m), water persistence (time) and plant species type and, as these have defined units or categories that are fully scalable in space and time, the classification system is applicable globally whilst maintaining local relevance. EarthTrack and Living Earth uniquely includes a new approach to classifying change that is based on the coupled descriptions of the causes and consequences, considering biotic, abiotic and human-influenced drivers. The maps generated are made publicly available to inform individuals, groups, organisations and even countries across multiple domains (policy, science, land management, society and health). Living Earth has been developed in Wales and Australia, with European effort, and applied at local, national and continental scales.

Curious about nitrogen pollution in your area? This app helps you assess local nitrogen air quality using lichens—good indicators of nitrogen pollution levels in the atmosphere. Knowing nitrogen pollution levels can tell us a lot about the health of your local environment. It provides: • A simple lichen ID photo guide for nitrogen-sensitive and tolerant species • Easy tools for recording lichens on trees and branches • A step-by-step field guide for conducting surveys • An automatic nitrogen air quality index score (NAQI) • Clear pollution zone results: Clean, At Risk, Nitrogen Polluted, or Very Polluted Use nature to understand your air quality and environment!
