High Resolution Imagery from National Map

• The four band NAIP allows selection of either true color or false color IR.  The "A" in NAIP stands for agriculture, so it might also be leaf on, making things hard to see on the ground.  Non agricultural users like geologists or hikers often prefer leaf off imagery to see through the trees.
• You may have to decide if you lots of detail for a small area, or a larger area with less detail.
• The data is in prestaged tiles, mostly in JPG2000 format (lossy compression).  You will need GDAL to open the imagery in MICRODEM. 

Some of these data sets are in WGS_1984_Web_Mercator_Auxiliary_Sphere projection.  You can verify this by looking in the Geotiff File Metadata for the Geotiff created by GDAL.  If the program does not automatically correct this, you must warp the image to usable UTM coordinates, on the Resample menu. 

If you need to merge tiles, get ready for the command line using GDAL.  MICRODEM should hide the messy details.   Do any merges before you warp.
