Aerial photography

Wisconsin's Statewide Forestry Aerial Photography Program includes stereoscopic coverage for the entire state. Current photography varies across the state from 1997 to 2003. Aerial photos from 1997 to 2003 are summer, black and white infrared with a scale of 1:15,840 (four inches to the mile). Aerial photos for the 2007 to 2014 flights are taken during the fall, and are color infrared with a scale of 1:15,840.

Contact prints

Contact prints are 9-by-9-inch images printed on photographic paper with an approximate scale of 1" = 1,320'. Each print covers approximately a four square mile area, or around 2,600 acres.

Orders of one through nine prints may be ordered by using the legal description (i.e., township, range and section number). This information can be found in numerous locations including plat books (available through county clerk offices or from mapping companies) and the Wisconsin Atlas and Gazetteer (available at many bookstores, gas stations or discount stores). A legal description looks like this: "T 26 N, R 12 E, S 18" where "T" is for township, "R" for range and "S" for section.

Orders of 10 or more prints must include the county flight line number, negative roll number and photographic frame number. These numbers are available on photo index maps, which can be found at DNR field offices or by calling the Division of Forestry at 608-267-7494.

Stereoscopic viewing

Stereoscopic viewing provides the third dimension of height. Think of what you see when you're in an airplane. You can see differences in the heights of buildings, trees and topography, which is what you see when viewing aerial photos stereoscopically.

Overlap ImageThe aerial photos were taken with about 60 percent overlap in the flight line. Adjoining flight lines overlap each other by about 30 percent. This allows an image to appear on at least two consecutive photographs. This overlapping feature provides for viewing stereoscopically (in three dimensions) by aligning two consecutive photos and using a stereoscope. Enlarged aerial photos are generally too large for this purpose.

If you are interested in being able to view photos in three-dimension, at least two consecutive aerial photos must be purchased and viewed with a stereoscope.

Black-and-white IR versus color infrared

Forestry's Aerial Photography Project is in the process of converting from B&W IR to CIR. Each county is available in only one format depending on the year of acquisition. Refer to the map to determine whether the county you are interested in is available in B&W IR or CIR.

Contact print pricing

Prices are per print. Shipping and handling charges are based on the number of prints you order (e.g, the shipping charge is $12 whether you order 1 or 50 prints).

  1-50 prints 51-100 prints 101-250 prints 251-500 prints > 500 prints
B&W $9.95 $9.80 $9.45 $9.15 $8.95
Color $13.80 $13.45 $12.25 $10.50 $10.25
Shipping and handling $12 $14 $14 $16 $16 + $3/hundred over 500

Contact print delivery times

Orders are processed on a first in/first out priority. The delivery time for contact prints is based on the following order quantities:

  • 1-100 prints: 10 working days
  • 101-500 prints: 15 working days
  • 501-1000 prints: 30 working days
  • over 1000 prints: 60 working days

Digital prints

Digital scans are digital reproductions of the CIR negatives, with an approximate scale of 1 inch = 1,320 feet.  Each scan covers approximately a four-square-mile area, or around 2,600 acres.

The digital scans are reproduced from one-foot pixel resolution digital scans. Two digital scan products are available for purchase.

Raw

Raw scans are best described as digital pictures of the 9x9 print. While these scans must be viewed on a computer, they do not contain any geographic information in order to overlay them with other geographic data.

Geo-referenced

These scans have been geo-referenced using a global positioning system (GPS) coordinate tethered to the center point of each digital photographic frame to georeference the image to WTM NAD 83/91 (learn more about parameter definition of the WTM projection). While these scans are not to be confused with orthophotos--as they have not undergone the same correction methodology--they may be viewed with other geographic data.

Georeferencing is the process of scaling, rotating, translating and de-skewing the image to match a particular size and position. While viewing the scans in a geographic information system (GIS) is possible, analysis and any exact measurements should not be conducted.

Digital scan ordering details

As with ordering contact prints, orders of one to nine prints may be ordered by using the legal description (i.e. township, range and section number). This information can be found in numerous locations including plat books (available at your county clerk or from mapping companies) and the Wisconsin Atlas and Gazetteer (available at many bookstores, libraries, gas stations or discount stores). A legal description looks like this: “T 26 N, R 12 E, S 18” where “T” is for townships, “R” is for range and “S” is for section.

Orders of 10 or more prints must include the county flight line number, negative roll number and photographic frame number. These numbers are available on photo index maps, which can be found at DNR field offices or by calling the Division of Forestry at 608-267-7494.

Digital scans sample order

For orders of nine or fewer, digital scan reproductions may be ordered by a legal description (township, range and section). For orders of 10 or more, digital scan reproductions must be ordered by using the photo index map information (roll, flight line and frame numbers).

Proof prints

Proof prints are photocopies of contact prints that can be mailed or faxed to you. They are especially useful if you want to order an enlargement. Instead of viewing an original contact print at a DNR forestry field office, you have the option of ordering a proof print. Note that the quality of the photocopy is not as high as the original contact print and that the image is shrunk to fit on an 8.5-by-11 inch piece of regular, photocopy paper, which alters the one inch = 1,320 foot scale.

To obtain a proof print, contact the customer service department at HAS Images, Inc. [exit DNR] at 937-222-3856 or mail or fax the Forestry Aerial Photography Project Order Form [PDF]. There is a $10 per proof print processing fee that is not applied towards the cost of any future enlargement purchase.

Enlargement prints

If you are interested in a scale other than one inch = 1,320 feet (or you would like a larger print) then you may order an enlargement by doing the following:

  • View the 9-by-9-inch contact print or a proof print of the area of interest. You will be ordering an enlargement of an area on a photo (versus an area of the land) so you need to first view the photo before determining which area you want to enlarge. A copy of the contact print is available for viewing at the DNR forestry field office serving the county in which the land area coverage is located. Proof prints can be ordered by following the directions in the proof print section.
  • From the sectional diagrams below, select one of the 15 standard cropping options. When choosing the area of the photograph to be enlarged, the image should be oriented so that the photo date, roll line and frame number are at the top. Simply identify the area by letter and number (e.g., B2 or G14) and write it on the enlargement order form in the "Section Letter and Number" column. Please allow a minimum of two inches around your exact area of interest.
  • Select the scale at which you want your enlargement OR select the size of your enlargement. Selecting one option automatically determines the other. For example, if you want to order a B2 sectional with a scale of one inch = 400 feet, then the size of the enlargement will be 14-by-14 inches. These are the most common scale and size requested. To request other scales and sizes, please contact HAS Images, Inc. [exit DNR] directly.
  • Contact HAS Images, Inc. [exit DNR] to order your enlargement and for pricing information.

View digital orthophotos online

Digital orthophotos are available on the DNR webview DOP tracker. Ortho aerial photos (also known as digital orthophotos, or DOPs) are digital images of detailed, rectified aerial photographs that have been geo-referenced so they can be used with other map data. When displaying DOPs on your computer, you can zoom in and out, pan and print out portions of the aerial photos just as you would any other kind of map. You can also display a wide range of other DNR map data over top of the ortho aerial photos.
