A mechanism to alert data submitters the importance of including a lonlat file

[lqjiang]

The availability of a lonlat file will help automate the data archiving process significantly, by creating the browse graphic automatically, etc. I wonder if we could add some instructions to the file uploading interface to alert users the importance of including a lonlat file.

For gridded data, they can simply create a lonlat file covering the four corners of the bounding box. For example something like the below:

-179.5 89.5
179.5 89.5
179.5 -89.5
-179.5 -89.5

Adding all grid points there could overcrawd our Oracle database and slow down the searching engine.

Thanks,
