Projects

sandID
sandID is a tool that uses machine learning image analysis to identify the provenance and composition of a sample of sand. 

We are currently in the model training phase. During this time, we need as many images of sand from as many places around the world as possible. To streamline this process and provide opportunities for citizen scientists and other researchers to contribute to building this tool, we’ve developed a simple image upload application. 

If you are interested in contributing images to develop sandID, please contact me for a link to download the app.

Guidelines for Images in the sandID app

Our app has a simple workflow outlined with basic instructions to follow when you open it. It is important that the sample you are photographing is:

1) dry
2) sand (or mostly sand), meaning that most grains are less than 2mm in diameter

and

3) if entering the sample location manually, use decimal degrees with latitude and longitude separated by a comma: 32.987269, -96.748297

For our own lab samples, we place the sand in a 2 inch (5 cm) diameter PVC pipe end cap to have a standardized scale for reference. If you have easy access to such a pipe cap to use in images you upload, it makes our processing easier. If not, just follow the app instructions and it will be close enough. 

Our app is currently only available for Apple devices and works best on an iPhone. It will run on an iPad but the scaling is off. We are working on developing an Android version.
