[UW-GIS-L] NAIP $-band Orthoimagery (fwd)

[Harvey Greenberg]

Hooray for infrared!  I would like to see some documentation on data 
acquisition and processing.

Three-foot pixels?  We got 18" pixels for 2006.  Do these photos not 
warrant little pixels?

UTM meters or stateplane pixels?  I assume that the raw images were 
orthorectified once, then reprojected.  If that is true, I want the 
native format.

I would like lossless tiffs.  Any 21st-century software should support 
lossless LZW compression. We could certainly write a script to compress 
tiff file.  It would be a significant savings, wouldn't it?

Re loaner drives: I am a big proponent of using bare drives with docking 
stations.  If Terry ships a bare drive, I can loan you a docking station 
if don't have one yet.
