Abstract: Henderson County, NC county-wide black and white 1-foot, digital orthophotography for 2001 in compressed MrSID format. (.sid)
Purpose: With the development of the internet and the need to serve various data to remote users, this data layer was developed using MrSID file format and compression technology to represent high-resolution arial ortho-photographic images that could be viewed, managed and delivered easily. This layer was generated from high resolution .tif files used as base data in the creation of other layers, including parcels. These original .tif files were produced using the American Society of Photogrammetry and Remote Sensing (ASPRS) Accuracy Standards for Large Scale Maps.
