Satellite & GeoSpatial

We read the land from space.

Satellite imagery as ready-to-use blocks for agriculture, disaster management and district planning. Draw any district or farm; get hectares and polygons on a map, an AI note in Hindi, and alerts on WhatsApp and SMS.

How it works

From a place name to hectares on a map

  1. 01Satellite FetchSentinel-2, Landsat or Sentinel-1 SAR — by place name or a drawn polygon.
  2. 02Cloud MaskDrops cloudy pixels and scenes.
  3. 03Spectral IndexNDVI and other indices, with a threshold.
  4. 04Area & VectorizeHectares and polygons.
  5. 05Map OutputPNG + GeoJSON, a Hindi note, and a chat over the result.

Capabilities

What GeoSpatial Engine does

  • 01Satellite FetchSentinel-2 via Earth Search; Landsat and Sentinel-1 via Planetary Computer.
  • 02Bring your own imageryGeoTIFF Loader and pan-sharpening for sharper multispectral images.
  • 03Land-cover masksCropland only, water only — analyse just what matters.
  • 04Change DetectionBefore vs after, and a season tracked pass by pass with Time Series.
  • 05SAR Flood MappingRadar sees water through monsoon cloud, day or night.
  • 06Geo Query & StatsWorst zones and rankings, ready for an officer's decision.

Data sources

  • Sentinel-2
  • Landsat
  • Sentinel-1 SAR
  • Your GeoTIFFs

In practice

Where it is used

  • Kisan Mitra + satelliteEvery field checked on each clear pass; crop stress above a threshold alerts the block officer and farmers.
  • Aapda Sahayak (floods)SAR flood masks vs the dry-season baseline; affected hectares, villages and roads; relief flows start themselves.
  • District planningSeason time series and land-cover maps for review meetings.
  • Crop-loan checksOn the roadmap for banking and insurance.

Accountable by design

Built to be trusted

  • Public dataOpen Sentinel and Landsat imagery — map outputs carry no personal data.
  • Officer decidesThe AI only points; field visits, advisories and relief are the officer's call.
  • Approval before alertsEvery public message is approved before it goes out.
