Interactive Satellite Maps
Use the interactive sliders below to explore how satellite imagery and vegetation indices reveal land use changes across the Amazon region. Swipe between datasets like NDVI and SWIR, or compare high-resolution PlanetScope imagery to long-term Landsat data. These visual tools help uncover patterns of forest degradation, regrowth, and environmental transformation, giving you a clearer picture of what the numbers really mean on the ground.
Landsat 8 OLI/TIRS (30m) vs PlanetScope (3m) - Overview
This slider compares low-resolution Landsat 8 imagery with high-resolution PlanetScope data over the same region. Note the detail visible in the PlanetScope view, especially in river patterns, forest edges, and disturbed zones.
Landsat 8 OLI/TIRS (30m) vs PlanetScope (3m) - Plantation Site
This close-up view highlights how higher-resolution imagery (3m PlanetScope) captures small-scale changes missed in the coarser Landsat data. Useful for identifying minor clearings, agricultural plots, or early-stage regrowth.
NDVI Change Over Time
🟥 High values (red) – Dry surfaces (e.g., bare soil, deforested zones, urban areas, water)
🟨 Mid values (yellow) – Transitional or mixed moisture surfaces
🟩 Low values (green) – Moist surfaces (e.g., wetlands, forest canopy, moist soil)
This comparison shows Normalized Difference Vegetation Index (NDVI) change from 1990 to 2024. Reductions indicate vegetation loss or stress; increases point to regrowth or intensification of green cover.
🟩 High values (green) – Dense, healthy vegetation, water
🟨 Mid values (yellow) – Moderate vegetation or sparse growth
🟥 Low values (red) – Bare soil, built-up areas, stressed vegetation
Shortwave Infrared (SWIR) imagery reveals changes in moisture and surface exposure. Increased reflectance often signals deforestation, urbanization, or drying; decreased reflectance may indicate regrowth or wetter conditions.
