Installing

1. Become a trusted Google Earth Engine (GEE) tester (https://signup.earthengine.google.com/#!/)

2. Install package using pip (pip install geeViz) folder

3. Authenticate using the GEE cli in a cmd prompt (earthengine authenticate)

4. You can also install with git. If installing this way, first install the Python GEE package (pip install earthengine-api)

5. Then clone this repository (git clone https://github.com/rcr-usfs/geeViz) into your Python's site-packages

6. To stay up to date, pull the latest commit (git pull origin master)

7. This repository is also available within the FS gitHub instance (https://code.fs.usda.gov/forest-service/geeViz)

   • To add this instance to your local git instance execute remote add https://code.fs.usda.gov/forest-service/geeViz in a git bash
   • Now you can pull the latest from your origin (git pull origin master) or github (git pull github master)

Using

• Several examples are available within the examples module to help you get started. To test, enter the following command within the Python build you installed geeViz in:

  • from geeViz.examples import geeViewExample

• Other examples are:

  • from geeViz.examples import getLandsatWrapper
  • from geeViz.examples import getSentinel2Wrapper
  • from geeViz.examples import harmonicRegressionWrapper
  • from geeViz.examples import LANDTRENDRWrapper

• When these examples are run, a viewer should open in your default browser. It will show any data that was added to the map.

• Layers can be toggled on/off and opacity changed. They can also be measured and queried under the TOOLS pane.
