The DECam NEO Survey (PI Lori Allen) is using DECam to measure the size distribution of Near-Earth Objects from 1 km to 10 m. The survey has measured 235 unique NEOs, implying the existence of 4 million NEOs larger than 10 m (Allen 2016). The first Data Release of objects and measurements is available through the Data Lab.

For more information on the survey, see the presentation from the Science with DECam meeting (https://www.noao.edu/meetings/decam2015/files/LAllen_DECam2015_v3.pdf).
