Here are some of the details for the 2009 Aerial Photography Acquisition project that includes 1 meter color NAIP imagery for some portions of Utah and smaller areas where 6 inch photography will be collected for agencies providing partnering funding for specific areas at a higher resolution imagery. Click on the map to view a more detailed representation of the acqusition areas.
Acquisition Plan Details:
Spring acquisition March-April, leaf off and no snow (Exception: Cache will be acquired in the fall)
Final delivery no later than September 30, 2009
25cm resolution (1 foot), 3 band natural color, 4327 total square miles (to be included and distributed as part of the State Geographic Information Database
810 square miles of this will be collected as 12.5cm (6 inch). These products will be owned by partnering organization but will be resampled to 25cm for inclusion in the SGID
Control from 2006 will be reused and any additional control needed will be collected by the vendor
QA/QC will be performed by the USGS and partners

Partnering agencies for HRO 2009 (12.5 and 25 cm – 3 band natural color):
The Utah GIS community has another opportunity to develop partnerships to leverage federal funds for acquiring aerial imagery in 2009.
The USGS will support the acquisition of one foot imagery along the Wasatch Front roughly from Spanish Fork to Brigham City and the Dugway Proving Ground. Apdf-based map shows the specific areas that USGS will fund within the light green boundary.
Through our partnership for the 2006 imagery, we were able to significantly increase the area covered as well as upgrading to a better resolution. We have an opportunity to use partnerships to aquire specific areas if your agency is interested in participating. Generally the better pricing was based on increasing the size of the areas that were contiguous. The flight would be in the spring of 2009 for the USGS areas. Vendor(s) will be selected through the state's purchasing processes. An invitation to be will be issued mid-Oct. that requests pricing for one-foot and six-inch natural color imagery for various sizes of acquisition areas. Potential partners will be able to use this pricing matrix to determine what areas they would like to acquire. By the end of December 2008 all partnership agreements must be signed to allow the AGRC to complete contracts with selected vendors.
We have some time to get the details worked out, including getting your input to define the specs for the products, but would like to begin identifying partners. If your agency is interested in participating, please contact:

The High Resolution Orthophotography (HRO) 1 foot Color Aerial Photography from 2006 has started arriving at AGRC. Check the status graphic at http://gis.utah.gov/images/sgidraster/Available_HRO2006.jpg to see if your area(s) of interest is available yet. Each tile block is in GeoTIFF file format, is named according to US National Grid standards, and covers a 4000×4000 meter area. The file sizes for these blocks are around 740mb. As the various tiles arrive they will be available through ImageServer and FTP download (see below). If you need large areas covered by the imagery, it is suggested you deliver or mail an external hard drive on which to upload the data to Rick Kelson at AGRC.
About FTP download of the new HRO imagery: The large file size of the HRO tile block GeoTIFF files results in long FTP download times and also the need for these files to be stored in two separate directories. All HRO tiles for areas north of the southern-most point of Utah lake will be available from ftp://ftp.agrc.utah.gov/Imagery/HRO2006_1Ft_No/HRO2006_1Ft_No/. HRO tiles south of the southern-most point of Utah lake will be available from ftp://ftp.agrc.utah.gov/Imagery/HRO2006_1Ft_So/HRO2006_1Ft_So/
Tips on using HRO Imagery in ArcMap In ArcMap, the HRO imagery is best viewed with a couple of changes to the layer properties. Add the HRO 2006 imagery (from ImageServer) as a layer in ArcMap. Right click the newly added HRO layer and choose Properties. Under the Display tab check the box next to “Make service background color transparent” and under the Service Properties tab change the Compression method to “Uncompressed” or “LZ77″. These adjustments to the HRO2006 Layer Properties will allow you to overlay the HRO imagery over other imagery data with a larger extent, like the NAIP2006 service, minimizing No Data or “Scalloping” issues.
Statewide aerial photography from Fall 2006, is now available as a single, mosaiced layer from the SGID Image Server. This 2006 NAIP layer has 1 meter, natural color pixels and can be accessed with ArcGIS and CAD clients using the free, downloadable Image Server client.
