The SGID ImageServer now provides 1:24K and 1:100K USGS topographic maps with a background hillshade. The background hillshade together with the topo map contours should make it easier to visualize terrain. The layers, found with the Scanned Maps folder, are named:
At v9.2, ArcMap does not allow Image Server images to be clipped to a custom extent and exported locally.
But, using the Image Server Viewer that installs with the Image Server client, you can zoom to your area of interest and export the image to a local file using almost any file type, geographic extent, and pixel size you desire.
In order to make the SGID Image Server imagery layers more friendly, all existing services have been renamed and grouped into category folders.
The old layer names (e.g. 100KDRG, 2006NAIP) will remain usable until March 1, 2008. After March 1st, the old layers will be deleted and any image service layers using the old layer names will no longer work. This means you'll want to delete the old image server layers from your ArcMap projects and add new ones from the newly created folders and layer names.
We realize that this will be an incovenience, however AGRC has received a volume of feedback on the Imager Server layer names usability. Hopefully, by making this one-time change, we will make using Image Server more intuitive.
AGRC now has statewide color infrared imagery derived from the 2006 NAIP flight. This imagery, although displayed in ArcMap as Red, Green, and Blue (RGB), actually displays the Near Red, Red, and Green bands in the imagery and is useful for discerning features such as vegetation that give off a distinct signature in the infrared spectrum. The CIR imagery is available through the SGID ImageServer (NAIP2006_CIR) and through FTP download as Quarter Quad TIFF files and Mr. Sid county mosaics.
