ArcGIS 9.2 has problems displaying rasters.  Some may be bug-related and some new-methodology-related.  Regardless, this affects display of the new 2006 NRCS NAIP county mosaic aerial photographs that just became available.

I've been getting my copies from the Conservation Commission FTP site.  They've been working to put them out and have 74 of 77 counties available for download.  I've gotten them all but have found the following problems that appear to be 9.2 related.

Of the 77 

*	3 Counties:  Mayes, Latimer, Le Flore   

	*	Not yet available on the OCC server. 

*	3 Counties:  Cherokee, Delaware and Pushmataha 

	*	Display at the wrong location, because the units display as fathoms when you look in layer properties in 9.2.  In 9.1 the units display as meters and the map displays at the correct location.  If you go into ArcCatalog and reset the Spatial Reference to UTM-15 NAD83 in meters, that fixes them. 

*	9 Counties 

	*	9.2 claims they have no georeferencing information and will not display them in combination with other data, but 9.1 finds it and displays them just fine.  These are all the ones that cross the UTM zone boundary between zones 14 and 15.  To fix them the spatial reference for the following counties to the indicated UTM zone in NAD83. 
	*	Zone 14 

		*	Atoka 
		*	Bryan 
		*	Hughes 
		*	Okfuskee 
		*	Osage 

	*	Zone 15 

		*	Okmulgee 
		*	Pittsburg 
		*	Tulsa 
		*	Washington 

*	Also, in a matter unrelated to ArcGIS 9.2, Comanche County is missing a patch of data about 3 miles wide by 8 miles high, in the NW corner of the county.
