Re: [las_users] LAS changes variable names/ dimensions on download

One of the other attributes that the saved file had was:

LON1_8648:point_spacing: "uneven" ;

which I thought was weird because the dataset that I am testing is regularly gridded (atleast it is supposed to be)

The fact that the size of the axis increased may seem odd.  Depending on the limits of the region that's been selected, the longitude request may have specified wrapping a bit more than 360 degrees around the globe.  Perhaps that's something we should prevent, so that the size of the dataset wouldn't be increased.

The download process always saves a sub-set based on the state of the selection widgets. The request to Ferret is always in world coordinates, not index space. So it's likely that the sub-set selected to be saved was slightly smaller that the full dataset.  Since it's writing a subset it makes a new axis with a new name.

Hi All,

I observed a couple of strange things when I recently downloaded a gridded data from LAS and saved it as a NetCDF file.

1. The dimensions of the lon variable changed from 8640 to 8648
2. the lon variable itself was renamed to LON1_8648

Why is this happening? Is this some kind of a bug? 

LAS 7.3 (Ferret 6.82)
