TNC California Conservation Technology EarthEngine Workflows

This repository contains EarthEngine work flows to be shared, used, and re-used by Conservation tech

Preparation (for all examples)

Please try to replicate and create Github issues whenever you get stuck. The goal is to have a tutorial that is easy to reproduce. Getting stuck will reflect on me, my writing, or my implicit assumptions.

1. Create a conda environment

Performan this step only once to get started with the project, everything created here will persist on your system unless explicitely deleted:

• Open your Conda enabled terminal (Windows: Cmd symbol in the Anaconda/Miniconda/Conda directory of the start menu). The prompt inidicating that you are in the conda base environment should look something like this:

  (base) C:/{...}
  

• Git clone this repo (make sure Git is installed) in a directory (wherever you would like to store it):

  git clone https://github.com/tnc-ca-geo/ee_workflows.git
  

• Install the conda environment defined within this project:

  • change directory (cd) to the ee_workflows folder created by git clone

  • create environment from the environment definition in this repository

  conda env create -f environment.yml     
  

2. Activate and update the environment and update code

Every time you work on the project

• Open a conda-enabled terminal

• Activate the conda environment created above

  conda activate ee_workflows
  

• It might be necessary to update the conda environment

conda env create -f environment.yml

• Pull the newest changes fom Github

  • change into the root directory of this project and call

  git pull origin master
  

3. Proceed to example projects

Change into the subdirectory for the project in question.

• Extract zonal statistics using a local shapefile and an EarthEngine image
