Water quality monitoring

Multispectral indicators of turbidity, chlorophyll-a, and algal blooms across entire river stretches and lakes — wall-to-wall context that sparse ground sensors cannot provide.

  • Whole-river coverage
  • Bloom & hotspot flags
  • Complements ground sensors

Benefits

What water quality monitoring unlocks

Short-term optimization

  • Locate pollution hotspots along hundreds of kilometres of river
  • Detect algal blooms in lakes and reservoirs early
  • Prioritise where ground sampling teams should go

Long-term impact

  • Seasonal and multi-year water-quality baselines
  • Programme-level evidence for river-rejuvenation missions
  • Encroachment and discharge patterns near water bodies

Approach & methodology

How the analytics work

We are transparent about data sources, models, and limits — so you can trust what you act on.

Data sources
10 m multispectral optical imagery with water-quality spectral indices; historical archives for baselines.
Approach
Index-based retrieval of turbidity and chlorophyll-a, calibrated against available in-situ measurements; anomaly detection for hotspots.
Update cadence
Each clear-sky pass; weekly composites in monsoon-affected periods.
Limitations
Optical retrievals are surface indicators, not lab assays; cloud and sun-glint reduce usable observations.

Deliverables

Expected outputs

  • GIS-ready data layers (GeoJSON / KML / SHP / GeoTIFF)
  • Decision-ready PDF report with interpretation
  • Interactive smart map with time-series view

Process

Project stages

2–4 weeks to first river-stretch assessment

  1. Define area of interest and indicators with your team

  2. Acquire and process multi-date satellite imagery

  3. Run analytics models and validate outputs

  4. Deliver layers, maps, and report; set up recurring monitoring
