The State of Delaware contracted with Earth Data (formerly PhotoScience) to update the 1992 1-meter resolution color-IR digital orthophotos series for Delaware with a 1-meter resolution greyscale digital orthophoto series. The state was re-flown in March/April, 1997. The airphotos were digitized and georeferenced to Delaware State Plane coordinates (meters, North American Datum 1983, based on GRS 1980 spheroid). The source data are TIFF-format ~50 MB 8-bit greyscale files for each of the 172 quarter-quads in Delaware.

To disseminate these data on the web, the Spatial Analysis Lab (UD) resampled the 172 DOQ's covering the state to 5-meter resolution without changing projection, using a nearest-neighbor (i.e. center-cell selection) resampling procedure which generates a high-contrast image with some blockiness in very small features. Most images were brightened and contrast-enhanced using Adobe Photoshop. To reduce file size and eliminate sun glare, large water areas are masked to black. These files are distributed in JPEG format in the original DE State Plane (NAD83 meters) projection.
