MAPSPAM (Spatial Production Allocation Model) is a professional agricultural geodata platform operated by the International Food Policy Research Institute (IFPRI). Its core goal is to downscale coarse-grained agricultural statistics at the national/provincial level into global crop distribution spatial data with a 10km grid resolution using the cross-entropy method, providing foundational data support for agricultural geographic research and policy planning. The platform currently hosts open data for multiple versions spanning 2000 to 2020, covering 42 major crops globally.
The platform's core features fall into three categories: First, the data center offers downloads for all versions of SPAM data. All datasets are hosted on the Dataverse platform, completely free and open to use with no registration required. Second, the map gallery supports online viewing, annotation, and downloading of single-crop distribution maps, making it easy to quickly preview data. Third, it openly shares complete methodology documentation, team information, and existing cited publications, helping researchers understand the model logic and standardize data citations. All resources on the entire platform are 100% free of charge, fully open to academic and public research use.
This dataset has been validated by hundreds of top academic publications worldwide, and its reliability is widely recognized in the field; it features a complete time series, broad global coverage, and a uniform format compatible with most GIS analysis tools, keeping the barrier to entry low.
The site has an outdated design with mediocre interactive experience; it only offers data downloads, with no online analysis or visualization functionality; the current version only has 10km resolution, which cannot meet the requirements of high-precision research for small regions; the platform only provides content in English, which is not user-friendly for domestic Chinese users.
Users in mainland China can access the website directly, and no proxy is required for data downloads. This platform is an ideal resource for university researchers and policy research institutions working in agricultural geography, climate change, and food security. It is a rare free, authoritative public data resource for the agricultural spatial research field.
