I received a question, regarding the WMS (Web Mapping Services): RGB: http://granitweb.sr.unh.edu:6080/arcgis/services/ImageServices/NH_2015_1ft_R GB/ImageServer/WMSServer CIR: http://granitweb.sr.unh.edu:6080/arcgis/services/ImageServices/NH_2015_1ft_C IR/ImageServer/WMSServer You can't view the URLs with a web browser. You need to open a client application capable of displaying a WMS. There are opensource clients available, but I used ArcGIS 10.3 1. open the ArcCatalog window in ArcMap 2. under "GIS Servers", click "Add WMS server" 3. paste the URL into the dialog, and click OK; no user or password is required I also downloaded ZIP files of SID images for several townships, using this GRANIT FTP link: ftp://ftp.granit.unh.edu/pub/GRANIT_Data/2015AerialPhotography_TownZipFiles I unzipped all the SID files to one folder; added all the SID files to an unmanaged Raster Catalog, using ArcToolbox "create raster catalog" and "workspace to raster catalog"; and added that layer to ArcMap for viewing off-line. Compared to the WMS, I found the compression ratio used to create the SID images degraded resolution slightly, when zoomed in at very small scales. I found that SID images looked a little better when I changed the ArcMap default layer properties for Color Correction, and turned on Color Balancing, Dodging Balancing, Single Color. However, to really see that 1-foot pixel resolution it may be worth acquiring the GeoTIFF images from GRANIT on a portable USB hard drive, if time and budget allow. ------------------------------------------------------------------------- This list (NEARC-L) is an unmoderated discussion list for all NEARC Users.
