Resource Abstract:
- description: <p>This imagery collected by the ND Department of Transportation was used to digitize road centerline vector
information for the DES Base Map Project. The digitized centerlines were created with a "sub-meter" accuracy. The
imagery were collected during optimum viewing conditions whenever possible, however maximizing flight mission time was also
a major priority. Ideal flying conditions would be during spring and fall seasons when tree and foliage cover is reduced,
thus optimizing the viewing accuracy of roadway centerlines. Other factors affecting image quality can be sun angle, haze,
wind speed, turbulence and cloud cover. The flight missions were prioritized to capture certain PSAP (Public Safety Answering
Point) areas ahead of other counties; However once again, weather conditions dictate where and when the flight crew can collect
data. Certain image anomalies will be visible within the mosaics. These small warpages were addressed during the digitizing
phase by using imagery imported from other stages of the process. It is the intent of NDDOT to eventually address all of these
anomalies.</p> <p>Pixel size is approximately 0.9-feet, data is processed to UTM-14, NAD83. The Base Map missions
were created at a flight height above ground (HAG) of 9,000' (2743.2 meters) which creates imagery with a .90'(27.432
cm) ground sample distance (GSD). The resultant imagery covers a base corridor 12,400' (3779.52 meters) wide. Imagery
collection dates range from November 2009 through November 2013.</p> <p><strong>Constraints:</strong><br
