|If you are looking for an aerial photograph
covering a portion of Bayfield County, you might be interested in
examining the new digital orthophotography that has recently become
An orthophoto is a digital image that is produced by making geometric corrections to traditional aerial photographs. The distortion in aerial photographs is removed by unwarping the effects of terrain, removing the perspective projection of the camera, and by fitting the image to a particular map projection to create an "image map" that has a uniform scale and a known accuracy. Hence, orthophotos can be used as a map whereas uncorrected aerial photographs cannot. In computer systems, they can be integrated with other geographic information providing a rich visual context.
Orthophotos have a variety of uses. They can be viewed and printed at various scales, and are extremely valuable in the development of land information systems and land use planning issues.
Obtaining ImageryOur online tool accessible through this web site called MapViewer which will allow users to explore county orthophotography in conjunction with many other map layers, including parcels and land cover.
If you would like to purchase orthophotography covering all or part of Bayfield County, you may do so by contacting the Bayfield County Land Records Department.
You can also download much of the Bayfield County orthophotography for free at the Microsoft TerraServer web site. While this data is essentially the same as the data available through the Land Records Department, it is not registered to any map projection, preventing it from being used in a geographic information system (GIS).
