Extent of available data.
This data layer is the 2002 to 2004 statewide multi-season orthophotography. It originated from the United States Geological Survey and has a 30 meter resolution. Orthophotography is extremely useful for determining land use and land cover. As a result of this, it can provide important context for specific locations and other spatial data. If multiple years are available, it can also be used to identify changes that take place on the landscape.
