Flood Depth
Fathom Global Flood Map shows water depth
in both views. Both views resample the 30 m source data smoothly:
Flat (depth) drapes a continuous depth map on the
terrain. 3D (water surface) raises a continuous
translucent water body to its true water-surface elevation
(WSE = ground + depth), so you can read how deep water gets.

Topographic Position Index
TPI measures the tendency of water to accumulate at any point in the landscape. Lower values indicate areas where water naturally flows and accumulates (valleys), while higher values indicate ridges where water would not flow.

Flow Accumulation
Flow accumulation translated to catchment area in hectares. Indicates how much upstream area drains through each point in the landscape.
Below 1 HA
Up to 1 HA
Up to 10 HA
Over 10 HA
Water Harvest Sites
Intersection of TPI (below −10) and Flow Accumulation (above 15 HA). These points indicate locations where topography can naturally hold water and where a large volume of upstream flow accumulates — ideal candidates for water harvesting.

Groundwater Table
Groundwater flow zones classified by hydrological behavior. Recharge zones absorb rainfall into the aquifer, transit zones convey water laterally, and discharge zones release groundwater to the surface (springs, rivers).

Water Concessions
Official water use concessions granted by CONAGUA. Point size reflects annual concession volume (m³/year). Color indicates water source type.

NDRE
Normalized Difference Red Edge index. Measures chlorophyll content and vegetation health using the red-edge spectral band, sensitive to canopy density and leaf structure.

Vegetation Classification
Multi-year NDVI analysis (Sentinel-2) identifying vegetation persistence zones — whether vegetation is permanently present, seasonal, intermittent, or absent.
Constant — always vegetated
Temporal — seasonally vegetated
Sporadic — rarely vegetated
None — bare soil / no vegetation
Soil Stability
Terrain stability from cosine similarity of Google Satellite Embeddings V1 (2017–2025, 10 m). Higher similarity indicates more stable terrain over time.
