<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This data set consists of 0.152-meter pixel resolution (approximately 0.5-foot), 4-band orthoimages covering the entire State of Delaware. With a total of 2,005 X 1700-meters by 1700-meters (2.89 square kilometers) full orthoimage tiles providing imagery in blocks on the ground with no "no data" space, the total area of the project is 5,794.45 square kilometers (2,237.25 square miles). This project also includes 0.076-meter pixel resolution (approximately 0.25-foot), 4-band orthoimages that covers select areas within the State of Delaware park system for the Department of Natural Resources and Environmental Control (DNREC), Division of Parks and Recreation. With each of the 116 X 1700-meters by 1700-meters (2.89 square kilometers) orthoimage tiles providing imagery in blocks on the ground, the total of the collective area is approximately 335.24 square kilometers (129.44 square miles). The 0.076 meter product is approximate in area because a "white data" space is present in areas outside the official boundaries of the delivery tiles. There is no image overlap between adjacent tiles. An orthoimage is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. The design accuracy is estimated not to exceed 1.52-meters NSSDA 95% confidence (0.88-meters Root Mean Squared (RMSE) Error XY (0.62 meter RMSE X or Y). The projected coordinate system is Delaware State Plane. The horizontal datum is NAD83 2011. The vertical datum is NAVD88. The units are in meters.</SPAN></P></DIV></DIV></DIV> |
