The Land Cover product is a high-resolution (1 meter) dataset that provides baseline land cover information in multiple formats to support different land management applications. It is derived from 1 meter or better resolution, 4 band color infrared imagery that is acquired typically on a 2 year cycle as part of the National Agriculture Imagery Program (NAIP) or a state orthoimagery acquisition project.
EarthDefine's Land Cover product offers significant advantages over traditional coarser resolution (30m or lower) land cover datasets. Our high-resolution data enables you to precisely map fine scale variations in the landscape in mixed landcover terrains that are crucial to accurately modeling a host of landscape processes.
