D:\SDP_S3_Uploads\draft_products\UG_ndvi_oct2017_1m_v1.tif en dataset This is a 1m resolution map of Normalized Differential Vegetation Index (NDVI) derived from resampled 0.6m 4-band orthoimagery collected as part of the USDA National Aerial Imagery Program. The NAIP tiles were mosaiced and bilinearly resampled to the standard UG 1m grid before calculating NDVI as (NIR-Red) / (NIR+Red). The NAIP Imagery for this area was collected on October 10th, 2017.
