Other Available File Formats

Full Information Formats These files contain all of the available metadata.

Partial Information Formats These files contain only some of the available metadata.
Columnar Table	A table with separate columns of numbers for each independent variable (i.e., grids) and for the data. This is an inefficient format, so you would have gotten a HUGE file for dataset of this size. This file will be approximately 132535296 bytes, with 4 columns of 8283456 numbers.
2-Dimensional Tab-Separated Tables Y X Table X Y Table	Tab-separated-values (tsv) file with information about the independent variables (i.e., grids). The list to the left allows you to specify the format of the table. Note: The variable running across the top of the table (identifing columns) is listed first and the variable running down the side of the table (identifing rows) is listed second.
