LGRIP30: Global Rainfed and Irrigated Cropland Map at 30m

LGRIP30_L3 Version 2 is a high-resolution global cropland dataset derived from Landsat 8 satellite time-series data. It classifies agricultural land into irrigated and rainfed categories at a 30-meter resolution for a nominal year of 2020. The product currently covers the conterminous United States, with global coverage planned for a later date.

Use Cases

• Assessing water use efficiency by comparing the spatial extent of irrigated versus rainfed agriculture.
• Modeling crop yield potential based on water availability and irrigation infrastructure.
• Monitoring changes in agricultural land use and irrigation practices over time.
• Informing food security policy by identifying regions dependent on rainfall versus artificial watering.

Strengths

• Provides high-resolution 30-meter pixel data, enabling detailed field-level analysis.
• Uses Landsat 8 time-series data from 2019-2021 to create a robust nominal 2020 product.
• Includes an accuracy assessment layer for each 10° by 10° tile, allowing for validation of classification results.

Limitations

• Current spatial coverage is limited to the conterminous United States; global data is not yet available.
• Specific row counts, file sizes, and detailed column/attribute information are not provided in the available metadata.
• The license is listed as 'other-license-specified' but no specific license terms are detailed.
