CropHist

About CropHist

CropHist is built by Digifarm — AI-powered satellite data for agriculture. Digifarm delivers field delineation, deep-resolution imagery (Sentinel-2 at 1 m), Sentinel-2 time series, crop classification, sustainability indices, and productivity zones to insurers, agribusiness, paying agencies, and sustainability programs.

We combine Digifarm's field boundaries and crop classification with national crop data to give every field a full rotation history. In-season crop identification is coming soon — current-season crop predictions available weeks before official national products. The dataset now covers 62+ million fields across 4 countries, with Europe next.

What you can do

• Browse the map at any zoom level — raster crop colors at low zoom, individual field polygons at high zoom
• Use the year slider to see how cropping patterns changed over time
• Click any field to see its full crop rotation history
• Click a crop in the legend to highlight fields with that dominant crop

API

Everything on this site is available as a REST API — field lookup by ID or lat/lng, batch lookups, polygon zonal analysis, and bulk exports. Free tier included (100 lookups / day, no credit card). See api.crophist.com for full docs, pricing, and sign-up.

MCP (AI agents)

CropHist exposes 9 tools over the Model Context Protocol, so you can ask Claude Desktop, Claude Code, ChatGPT / Codex, or any other MCP-capable AI agent about crop rotations in natural language. Install with npx -y crophist-mcp, or point your agent at the hosted endpoint mcp.crophist.com. See mcp.crophist.com for quickstart & the tool list.

Data sources

Methodology

For each field and year, zonal statistics are computed by intersecting the Digifarm field polygon with the national crop raster. The crop code covering the largest fraction of the field is recorded as the dominant crop, with a minimum coverage threshold applied.
