NEON AOP Data
Currently the NEON AOP data is distributed through a Citrix account. When data is requested, users are given their own account through which they can access the data. For the Data Institute, we’ve created a single download that contains the files needed for the tutorials during the Institute.
We recommend downloading the complete Data Institute 2017 teaching data subsets from the button in the instructions below (direct download from Citrix).
Download & Uncompress the Data
First, we will download the data to a location on the computer. To download the data for this tutorial, click the blue button Download NEON Teaching Data Subset: Data Institute 2017.
Caution: This file set includes hyperspectral and lidar data sets and is therefore a large file (12 GB). Ensure that you have sufficient space on your hard drive before you begin the download. If not, download to an external hard drive and make sure to correct for the change in file path when working through the scripts.
After clicking on the Download Data button, the data will automatically download to the computer. This is a large file so it might take a while to download.
2) Locate .zip file
Second, we need to find the downloaded .zip file. Many browsers default to downloading to the Downloads directory on your computer. Note: You may have previously specified a specific directory (folder) for files downloaded from the internet, if so, the .zip file will download there.
3) Move to RSDI-2017 directory
Third, we must move the data files to the location we want to work with them. We recommend moving the .zip to create a dedicated subdirectory within a data directory in the Documents directory on your computer (~/Documents/data/RSDI-2017). This RSDI-2017 directory can then be a repository for all data subsets you use for the NEON Data Institute tutorials.
Note: If you chose to store your data in a different directory (e.g., not in ~/Documents/data/RSDI-2017), modify the directions below with the appropriate file path to your RSDI-2017 directory.
Fourth, we need to unzip/uncompress the file so that the data files can be accessed. Use your favorite tool that can unpackage/open .zip files (e.g., winzip, Archive Utility, etc). Depending on the tool you use to uncompress the files, you may need to individually uncompress the individual files within the main file.
5) Combine the Subsets
Fifth, we need to put all three data subsets within a single directory structure. The directory should be the same as in this screenshot (below).
Due to difference in the tools used to uncompress the zipped files, the name of the directory you initially see once unzipping is complete may differ.
You will now have all the teaching data subsets that will be used in the NEON Data Institute 2017.
