Earth remembers.
We quantify the rupture.
ForestGuard turns petabytes of raw Sentinel-2 and Landsat multispectral reflectance data into surgical, auditable alerts of illegal logging, lacustrine desiccation, and unauthorized ground disturbance.
Empirical ground truth.
Captured before the record is altered.
Every flagged polygon compiles multispectral indices, confidence distributions, and historic baseline vectors ready for legal or regulatory submission.
Tapajós Primary Canopy Desiccation & Logging Spurs
Pará, Brazilian Amazon
Autonomous multi-temporal optical analysis isolated high-confidence spectral degradation along the Rio Tapajós buffer. Detection triggered by B8/B4 near-infrared absorption shifts indicating mechanized clear-felling.
- ›Identified herringbone logging branch penetrating 4.8 km into protected indigenous perimeter.
- ›Surface canopy reflectance dropped from NDVI 0.81 to 0.23 within 42 days.
- ›Corroborated by Sentinel-1 Synthetic Aperture Radar (SAR) polarization coherence drop.
Elephant Butte Surface Lacustrine Contraction
Sierra County, New Mexico, USA
Modified Normalized Difference Water Index (MNDWI) time-series reveals dramatic littoral contraction in the upper basin, exposing evaporite sediment crusts and disrupting downstream municipal flow allocations.
- ›Shoreline retreated 420 meters eastward across shallow northern bays.
- ›Sediment resuspension and albedo increase confirmed via short-wave infrared (SWIR-2) profiling.
- ›Estimated water volume storage deficit of 38.4 million cubic meters.
Balcones Oak Savannah Impervious Encroachment
Travis County Peripheral Corridor, Texas
Rapid industrial megastructure conversion across primary limestone catchment basins. High-albedo concrete distribution hubs detected prior to local municipal registry updates.
- ›24.8 hectares of high-density oak canopy clear-graded and paved.
- ›Surface runoff velocity index modeled to increase by 310% in the adjacent creek basin.
- ›Heat island delta elevated local radiant surface temperature by +4.2°C.
We do not rely on single-frame snapshots.
We model the temporal velocity of change.
Standard optical remote sensing is deceived by seasonal leaf senescence, atmospheric cloud shadows, and orbital sun-angle variations. ForestGuard applies harmonized multi-temporal matrix math to isolate irreversible biophysical deviations.
Canopy Cell Rupture
Chlorophyll strongly absorbs red light (B4) while mesophyll leaf structure reflects near-infrared (B8). Clear-cutting causes an instantaneous inversion in reflectance ratio.
Aquifer & Surface Retreat
Short-wave infrared (SWIR) suppresses built-up noise and dry soil confusion, yielding precise littoral boundaries even in high-sediment river corridors and shrinking reservoirs.
All-Weather SAR Radar
When continuous tropical cloud cover blinds optical sensors, C-band Synthetic Aperture Radar penetrates moisture to detect surface roughness disruptions and heavy machinery trails.
“Environmental destruction relies on temporal latency. By the time field rangers reach an unmonitored basin, the timber is processed and the ecosystem is irrecoverable. ForestGuard shrinks the alert horizon from six months to six hours.”
Deterministic Processing Pipeline
From raw telemetry downlink to cryptographically signed ecological alert reports.
Constellation Sync
Continuous ingestion of ESA Copernicus Sentinel-2 Level-2A bottom-of-atmosphere (BOA) surface reflectance tiles.
Atmospheric QA
Sen2Cor scene classification masks clouds, cirrus, snow, and shadow artifacts with sub-pixel coregistration.
Temporal Matrix
Pixel-level differencing against baseline seasonal medians across NDVI, MNDWI, and NDBI spectral tensors.
