The world’s largest public repository of African soil chemistry data.
AfSIS DB is a web portal providing an interface for uploading, searching, and downloading soil chemistry data. It provides a lightweight and centralized laboratory information management system in the cloud for soil laboratories affiliated with the AfSIS project, including The World Agroforestry Centre (ICRAF), the Tanzania Soil Information Service (TanSIS), the Ghana Soil Information Service (GhaSIS), Rothamsted Research, and One Acre Fund (OAF).
The georeferences table stores the latitude and longitudes of all soil sample numbers, allowing multiple labs to know where soil samples came from. Simple map visualizations for these locations are also automatically created.
Spectroscopy readings collected from proprietary hardware are stored their original, raw binary formats in S3. We do this to preserve numerical precision and avoid transcription errors. Upon upload, input validation code is executed to check for possible misconfigurations of the spectroscopy hardware.
AfSIS DB supports multiple kinds of searches across data tables:
New data entries can be uploaded in many different ways, including CSV imports, folder synchronization, and manual entry into fields.
