Carbon and vegetation analysis for priority ecosystems in Cojedes
A Google Earth Engine app that reads vegetation indices and carbon densities across 14 priority ecosystem zones, with a step-by-step guide.
The challenge¶
Scientific results are hard to review when they live in a script. The aim was to make an environmental analysis understandable and checkable for people who do not code.
The solution¶
An Earth Engine app analyses 14 priority ecosystem polygons using Landsat 8 NDVI and SAVI for 2018, 2022 and 2026, links them to reference carbon densities by cover class, and walks the reader through the charts in eight guided steps, from data quality to cautious conclusions.
- Zones: priority ecosystems loaded from a KML, with a code per zone shown on the map.
- Indices: vegetation indices and cover changes over time.
- Carbon: reference densities by class, compared with independent sources.
- Guide: a numbered reading guide, map legends and GeoTIFF export.
Results¶
- 14 zones analysed across three dates in one reproducible app
- A built-in method note, so the audience can judge the limits of the estimates
- Downloadable layers for further work
