Dataset Basics

The Hamilton County 2009 digital natural-color orthophotography was collected on March 30 during leaf-off conditions at a resolution of 6-inch resolution. The data cover the entire land area of Hamilton County, Indiana, or 434 square miles. Data are delivered tiles, consisting of 2500'x 2500' uncompressed 24-bit natural color TIFF files.  Accuracy is +/- 2.50 feet. The entire perimeter of the county is buffered by at least 2,000 feet. Adjacent flight lines overlap by a minimum of 30 percent.  Imagery was collected with the Z/I Imaging DMC digital sensor.  The file naming convention is as follows: xxxyyyy where xxx and yyyy represent the easting and northing coordinates (respectively) in state plane feet, divided by 1000, of the tile origin (the bottom-left pixel).  TIFF files are approximately 75 MB in size.  Ownership of the data products resides with Hamilton County.
