Many states have high-resolution photos for agricultural and survey purposes, but you may need ArcMap or similar software to rigorously rectify them to a lat/lon grid.  You can try Googling for "Farm Service Agency" or FSA and something like "orthophoto".  Nebraska has some 1-meter imagery available for this.  

You can also try the USDA's website at http://datagateway.nrcs.usda.gov/ and see if they produce something in a useful format for you.  It appears any of their recent ag survey imagery is only available in a MrSID format, which will require a GIS client like ArcMap for use.
