Data-Driven Finding
All findings in this report are derived from Sentinel-2 satellite remote sensing data — not self-reported by the asset owner. The 7.5% NDVI decline and approximately 24-acre western disturbance zone are satellite-observable facts, on record.

Current Environmental State
What is the current surface condition of this parcel? Is there anything that should not be there?
WEIGHT · 50%
Methodology · Data Sources
Using2024 summer Sentinel-2 L2A imagery（云量<20%，中位数合成）to assess current surface conditions. RGB true colour (surface appearance) and SWIR shortwave infrared (subsurface moisture anomalies, soil composition, industrial disturbance signatures) are analyzed.

RGB Observation
The parcel is predominantly agricultural land with good vegetation coverage. A structure (high-reflectance white body) is visible in the northwest — consistent with a known farm building or industrial facility. Township Road 232 clearly crosses the southern boundary; Range Road 283 defines the western edge. No large-scale hardscaping or industrial contamination signatures detected.
SWIR Observation
Most of the parcel shows bright green (healthy vegetation, adequate moisture). The northwest structure appears magenta/white (hardscaped surface signature). The southeast quadrant displays yellow-orange tones, indicating lower soil moisture or surface disturbance. No hydrocarbon seepage signatures or anomalous thermal hotspots detected.

Historical Trajectory Finding
2020至Year 2024间，地块整体NDVI Mean下降7.5%（0.533→0.493），约24英亩区域（占地块25%）NDVI下降超过0.1。下降区域主要集中在西北侧（最显著）、西南侧上部及东南角。这一变化与西侧工业设施扩张或土地整备活动的时间节点相吻合，需在正式尽调中核实具体原因。
Signal Requiring Attention
The northwest zone shows the most significant change, consistent with the known structure location — likely construction disturbance or hardscape expansion. The southeast corner change source requires further investigation. Pro Edition upstream watershed analysis recommended.

Surrounding Environmental Pressure Scan
What is within 500 metres that could affect this parcel — now or in the future?
纳入LAYER 01权重
Methodology
Satellite imagery and public infrastructure data are used to identify environmental pressure sources within a 500-metre buffer around the AOI boundary.
Known Surrounding Context (Public Facts)
The parcel is adjacent to theCPKC Main Line (north), with 5-minute access to Calgary Ring Road (Stoney Trail) and 3-minute access to Glenmore Trail. Industrial and logistics facilities are already established nearby, within the Rocky View County-approved Prairie Gateway Area Structure Plan.

| Pressure Source | Category | Satellite-Estimated Distance | Risk Transmission Pathway |
|---|---|---|---|
| CPKC主铁路线 | Transportation Infrastructure | Within ~100m of AOI north boundary | Hazardous goods transport risk; noise; vibration |
| Township Road 232 | Transportation Infrastructure | AOI south boundary | Traffic pollution deposition; surface runoff |
| Range Road 283 | Transportation Infrastructure | AOI west boundary | Traffic pollution; access corridor |
| 西侧工业设施 | Industrial Activity | AOI west boundary毗邻 | Airborne particulates; noise; potential fugitive emissions |
| 周边湿地水塘 | Hydrological | 100–300m outside AOI boundary | Seasonal ponding; soil moisture fluctuation |
Buffer Zone Assessment
Rail and road infrastructure constitute moderate transportation pressure. The western industrial facility is the most significant proximate pressure source. Multiple wetland ponds are visible in satellite imagery outside the AOI boundary, indicating a relatively high water table — foundation treatment costs during construction should be assessed.
