The developmental version of the package has been tested on the following systems: Linux: Ubuntu 22.04 # Installation Guide 1. Users should build Python (3.9) and Julia (1.9) environment first. For Python, visit [https://www.anaconda.com/download](https://www.anaconda.com/download) to download and install the Anaconda distribution. For Julia, go to [https://julialang.org/downloads/](https://julialang.org/downloads/) and download the Julia installer for your platform. Follow the installation instructions provided on these websites. 2. Compile the libraries. ``` cd SRCJl\Flib\sitep bash compile_site_percolation.sh ``` # Prepare Data 1. Download data from GEE by using the [GEE_Data_Download_Script](./GEE_Data_Download_Script) and [shapefile](./Shapefile). 2. Place the data in the corresponding path: - MODIS EVI V6 (QTP): [Code/Tibet/Data/Tibet_EVI_V6/Summer](Code/Tibet/Data/Tibet_EVI_V6/Summer/) - MODIS EVI V6 (Sahel) : [Code/Sahel/Data/Sahel_EVI_V6/Summer](Code/Sahel/Data/Sahel_EVI_V6/Summer/) - TerraClimate Summer precipitation (QTP) : [Code/Tibet/Data/Tibet_TerraClimate_pr_Summer](Code/Tibet/Data/Tibet_TerraClimate_pr_Summer) - TerraClimate Summer precipitation (Sahel) : [Code/Tibet/Data/Sahel_TerraClimate_pr_Summer](Code/Sahel/Data/Tibet_TerraClimate_pr_Summer) # Demo ``` cd Code/Sahel/EVI_Percolation bash run_all.sh ``` ``` cd Code/Tibet/EVI_Percolation_Shuffle bash run_all.sh ``` ``` cd Code/Tibet/EVI_Percolation_Snapshots bash run_all.sh ``` ``` cd Code/Tibet/EVI_Percolation_Protection bash run_all.sh ``` ``` cd ode/Tibet/EVI_Enhanced bash run_all.sh ```
