How do I access GEMS Exchange?
To gain access to our growing portfolio of APIs, learn through the documentation and information on generating an API key.
Can I use the APIs from GEMS Exchange if I don’t program in any language?
The APIs are back-end data streams that are used to solve agri-food challenges. Aside from the GEMS Exchange PreView on this page, which allows you to toggle various API streams on and off, most activities require you to embed the APIs in your own custom programming code. However, we are reaching out to other organizations and expect to see an increasing number of commonly used visualization platforms utilize our APIs on the backend.
What languages can I use with GEMS Exchange APIs?
Currently, the two most common languages used in data science can be used, R and Python.
Can I use GEMS Exchange APIs within the GEMS Platform?
Yes! Open notebook within a JupyterHub session in GEMS, check out the tutorial video for each API, and you are ready to go.
Where else can I use GEMS Exchange APIs?
You can use the GEMS Exchange APIs from anywhere within your Python or R code. On your laptop, from a remote machine, or from within GEMS in your browser.
What’s GEMS Grid all about?
The GEMS Grid is a discrete and nested hierarchical grid system that is based on the EASE-Grid 2.0 projection. GEMS Grid divides up the (Ag-relevant) planet (i.e., Global minus the oceans and Antarctica) into discrete grid cells at varying resolutions. The coarsest resolution level has 36 km grid spacing. All grid cells at subsequent levels with finer resolution fit perfectly into their parent cells, with the finest level of cells splitting the terrain into 1 meter squares. The GEMS Grid API has all the functionality you need to map geographic coordinates (longitude, latitude) on the grid as well as resample the data up to coarser resolution levels based on specified mathematical rules (e.g., mean, min, max, sum).

How does GEMS choose the data sets made accessible via GEMS Exchange?
GEMS has prioritized the creation of new APIs based on how they (1) fit into the needs of the GEMS research objectives, (2) interoperate with existing APIs, and (3) align with the requests of multiple GEMS community members.
What if I want to use an existing API, but my crop isn’t included?
The analytics underpinning each GEMS API is designed to be extensible. If your crop, or details thereof (such as the coverage of traits or agro-ecologies in our multitrait predictor tool) are not in the Exchange we are certainly open to consider adding it. We are, after all, rooted firmly in a discovery driven university!
To enquire, contact the GEMS Solutions team. Please include details of the crop, particular problem, and country coverage of concern and we will get back in touch.
If I have a novel problem, can GEMS Exchange help me?
We are about data driven solutions for the agri-food sector from molecule to market. The GEMS team is distinguished by its transdisciplinary expertise linking cutting-edge data science to the disciplinary domains spanning the food, agriculture and natural resource sciences. Translational R&D is also in our DNA – professional papers and kudos are good, real world impact is paramount. We work on pre-, on- and post-farm problems from ideation, through basic, applied, pre-commercial and commercial innovation.
If you think your problem might be a good fit for us, by all means get in touch with our GEMS Solutions team. If we can’t help, we may know who might be able to.
