These original input rasters are in GeoTIFF format and because there are two UTM Zones in Connecticut, the input rasters are in either the NAD 1983 UTM Zone 18N Meters or NAD 1983 UTM Zone 19N Meters. The individual rasters were projected to NAD 1983 StatePlane Connecticut FIPS 0600 Feet and merged together in the resulting statewide mosaic. The 20090728 edition corrects an error found with one quarter quadrangle input raster (4107101_se_19_1_20080710.tif) that was improperly georeferenced. Using ESRI ArcGIS 9.2 software, statistics for the pixel color values in the image have been calculated and stored with the imagery data. This has been done to improve drawing performance and to easily manage how color bands are displayed. Depending on the GIS software used to view the image, the creation of these statistics may result in a default display of the raster mosaic in extreme colors values rather than in a natural color scheme. However, this can be changed with most software. For example, when viewing the imagery with ESRI ArcMap software, change the Symbology Stretch setting from a value of Standard Deviation to None to achieve a more natural range of colors for both color and color infrared displays. Apply these band settings to obtain full color imagery. Red = Band 1 Green = Band 2 Blue = Band 3 Apply these band settings to obtain color infrared imagery. Red = Band 4 Green = Band 1 Blue = Band 2</pre> </div><br></div> <ol> <li><a name="what.1"><b>How should this data set be cited?</b></a><br><br><div style="margin-left:20; margin-right:40">USDA-FSA-APFO Aerial Photography Field Office, State of Connecticut, Department of Environmental Protection, 20090310, Connecticut 2008 NAIP 4 Band Color and Color Infrared Orthophoto: USDA-FSA-APFO Aerial Photography Field Office, Salt Lake City, Utah. </div><br><div style="margin-left:20"><i>Online links: </i><ul> <li TYPE="disc"><a target="viewer" href="http://www.fsa.usda.gov/FSA/">http://www.fsa.usda.gov/FSA/</a></li> <li TYPE="disc"><a target="viewer" href="http://www.ct.gov/dep">http://www.ct.gov/dep</a></li> </ul><br></div> <div style="margin-left:20"><i>Other citation details: </i><div style="margin-left:40">The 20090730 edition corrects an error found with one quarter quadrangle input raster that was improperly georeferenced.</div><br></div> </li> <li><a name="what.2"><b>What geographic area does the data set cover?</b></a><br><br><div style="margin-left:20"> <div>Bounding coordinates:</div> <div style="margin-left:40"> <div><i>West: </i>-73.771496</div><div><i>East: </i>-71.732821</div><div><i>North: </i>42.071144</div><div><i>South: </i>40.932939</div></div> </div><br></li> <li><a name="what.3"><b>What does it look like?</b></a><br><br><div style="margin-left:20"> <div><a target="viewer" href="http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcolorfullview.jpg">http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcolorfullview.jpg</a> (JPEG) </div> <div style="margin-left:40">Full view of Connecticut 2008 NAIP in full color</div> </div><br><div style="margin-left:20"> <div><a target="viewer" href="http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcirfullview.jpg">http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcirfullview.jpg</a> (JPEG) </div> <div style="margin-left:40">Detail view of Connecticut 2008 NAIP in color infrared</div> </div><br><div style="margin-left:20"> <div><a target="viewer" href="http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcolordetailview.jpg">http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcolordetailview.jpg</a> (JPEG) </div> <div style="margin-left:40">Detail view of Connecticut 2008 NAIP in full color within vicinity of the University of Connecticut at Avery Point in Groton, Connecticut.</div> </div><br><div style="margin-left:20"> <div><a target="viewer" href="http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcirdetailview.jpg">http://www.cteco.uconn.edu/metadata/dep/browsegraphic/orthophoto2008naipcirdetailview.jpg</a> (JPEG) </div> <div style="margin-left:40">Detail view of Connecticut 2008 NAIP in color infrared within vicinity of the University of Connecticut at Avery Point in Groton, Connecticut.</div> </div><br></li> <li><a name="what.4"><b>Does the data set describe conditions during a particular time period?</b></a><br><br><div style="margin-left:20"><i>Calendar date: </i>20080703</div> <div style="margin-left:20"><i>Calendar date: </i>20080710</div> <div style="margin-left:20"><i>Calendar date: </i>20080711</div> <div style="margin-left:20"><i>Calendar date: </i>20080715</div> <div style="margin-left:20"><i>Calendar date: </i>20080716</div> <div style="margin-left:20"><i>Currentness reference: </i></div> <div style="margin-left:60"> <pre id="fixvalue">ground condition</pre> </div><br></li> <li><a name="what.5"><b>What is the general form of this data set?</b></a><br><br><div style="margin-left:20"><i>Geospatial data presentation form: </i>Fgdb raster digital data</div><br></li> <li><a name="what.6"><b>How does the data set represent geographic features?</b></a><br><br><ol TYPE="a"> <li><b>How are geographic features stored in the data set?</b><br><br><div style="margin-left:20"> This is a Raster data set.

Collected data was downloaded to portable hard drives and shipped to the processing facility daily. Airborne GPS / IMU data was processed and reviewed to ensure sufficient accuracy for project requirements. Planar rectified images were generated from the collected data for use in image quality review. The planar rectified images were generated at five meter resolution using a two standard deviation histogram stretch. Factors considered during this review included but were not limited to the presence of smoke and/or cloud cover, contrails, light conditions and sun glint. When necessary, image strips identified as not meeting image quality specifications were re-flown to obtain suitable imagery. Aerotriangulation blocks were defined primarily by order of acquisition and consisted of two to twelve strips. Image tie points points providing the observations for the least squares bundle adjustment were selected from the images using an autocorrelation algorithm. Photogrammetric control points consisted of photo identifiable points selected from base imagery provided by USDA FSA APFO. Elevations for the control points were sampled from USGS NED DEMs. The control points were loaded in to a softcopy workstation and measured in the acquired image strips. A least squares bundle adjustment of image pass points, control points and the ABGPS was performed to develop an aerotriangulation solution for each block. Precedence was given to the photo identifiable control points over control provided by the ABGPS solution in the bundle adjustment to ensure the final solution would agree with the provided base imagery within the required tolerances. The triangulated strips were ortho-rectified to the USGS NED DEM for the project area. The images were re-sampled from the raw resolution of 0.7 meters to the required resolution of 1.0 meters using a cubic convolution filter during the process. The red, green, blue, and NIR bands were combined to generate a final ortho-rectified image strip. The ADS40 sensor collects twelve bit image data which requires radiometric adjustment for output in standard eight bit image channels. The ortho-rectified image strips were produced with the full 12 bit data range, allowing radiometric adjustment to 8 bit range to be performed on a strip by strip basis during the final mosaicing steps. The imagery was mosaicked using a combination of automated and manual seamline generation. The 12 bit data range was adjusted for display in standard eight bit image channels by defining a piecewise histogram stretch. A constant stretch was defined for each image collection period, and then strip by strip adjustments were made as needed to account for changes in sun angle and azimuth during the collection period. Strip adjustments were also made to match the strips histograms as closely as possible to APFO specified histogram metrics and color balance requirements. Automated balancing algorithms were applied to account for bi-directional reflectance as a final step before the conversion to 8 bit data range. APFO specified DOQQs were extracted from the final mosaic in GeoTIFF format. Each DOQQ clipped from the mosaic was reviewed for conformance to APFO histogram metrics and color balance parameters using automated procedures. Images flagged for non-conformance were reviewed and adjusted manually on an image by image basis to bring them into conformance. In extreme cases, such as when a DOQQ was comprised primarily of water, modification of the histogram metrics to match targets caused severe degradation of image quality. In these cases, the water was masked out and histogram adjustments were applied to land. GeoTIFF tags for the appropriate UTM zone were then applied to all images </pre> </div><br><div style="margin-left:40"><i>Data sources produced in this process: </i><ul> <li TYPE="disc">Georectifed Image</li> </ul> </div><br></div> <div style="margin-left:20"> <div><i>Date: </i>20090403 (change 2 of 4) </div> <div style="margin-left:40"> <pre id="fixvalue">Using ESRI ArcGIS 9.2 software, an empty raster dataset was created and subequently populated with input rasters to create a statewide raster mosaic. The State of Connecticut, Department of Environmental Protection obtained these input rasters from the USDA-FSA-APFO Aerial Photography Field Office, 2222 West 2300 South, Salt Lake City, 84119-2020. STEP 1 - Create Raster Dataset - The Coordinate System for the raster dataset is NAD_1983_StatePlane_Connecticut_FIPS_0600_Feet. The image compression type is JPEG with a compression quality of 90. The Pyramid Reference Point X and Y coordinate are 687800 and 1015180, respectively. Bands: 4. Pyramids: 12 Bilinear. The Pixel Type is 8_BIT_UNSIGNED, which supports index values from 0 to 255.

The Ignore Background Value was set to one (1). The NoData value was left blank. The Mosaicking Tolerance value was set to zero (0). Consequently, pixel values in the raster mosaic resulted from a resampling of pixels values from individual input rasters due to the difference in alignment of input and mosaic (target) pixels. Note, in the resulting mosaic, the input rasters in NAD 1983 UTM Zone 18N Meters and NAD 1983 UTM Zone 19N Meters were projected to NAD 1983 StatePlane Connecticut FIPS 0600 Feet.

Using ESRI ArcGIS 9.2 software, statistics for the pixel color values in the image have been calculated and stored with the imagery data. This has been done to improve drawing performance and to easily manage how color bands are displayed. Depending on the GIS software used to view the image, the creation of these statistics may result in a default display of the raster mosaic in extreme colors values rather than in a natural color scheme, for example. However, this can be changed with most software. For example, when viewing the imagery with ESRI ArcMap software, change the Symbology Stretch setting from a value of Standard Deviation to None to achieve a more natural range of colors for both color and color infrared displays.</pre> </div><br><div style="margin-left:40"><i>Person responsible for change: </i><br><div style="margin-left:20"><div style="margin-left:20"> <div>Howie Sternberg</div><div>State of Connecticut, Department of Environmental Protection</div><div><pre id="fixvalue">79 Elm Street</pre></div> <div>Hartford, Connecticut 06106</div> <div>USA</div><br><div>860-424-3540 (voice)</div><div>860-424-4058 (FAX)</div></div> </div> </div><br><div style="margin-left:40"><i>Data sources used in this process: </i><ul> <li TYPE="disc">Georectifed Image</li> </ul> </div><br><div style="margin-left:40"><i>Data sources produced in this process: </i><ul> <li TYPE="disc">Mosaic</li> </ul> </div><br></div> <div style="margin-left:20"> <div><i>Date: </i>20090420 (change 3 of 4) </div> <div style="margin-left:40"> <pre id="fixvalue">Copied data from ArcSDE 9.2 raster dataset to FileGeodatabase 9.3 raster dataset format for data distribution purposes.
