Polygons to delineate date of digital orthophotography.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>In order to create one large seamless image, hand drawn seam lines are drawn in by orthophoto technicians to create a tie line between each image and the next. These lines are strategically drawn to minimize changes in the imagery caused by building and tree lean as well as tonal differences. This data set consists of the seamline polygons drawn for the 2007 - 2008 NJ Orthophoto mapping project, attributed with the date of each image used, merged into one layer, and dissolved to show the coverage area for each date of imagery used for the project. Please note that several records include multiple, disjoint polygons.</SPAN></P></DIV></DIV></DIV>
