Welcome to geeViz

GeeViz is a free open source Python package developed by RedCastle Resources for exploring and analyzing Earth observation data within the Google Earth Engine (GEE) platform. geeViz provides user-friendly functions to simplify complex data processing, analysis, and visualization tasks, acting as a toolkit to make working with GEE data more accessible.

Can be accessed from the GEE Community Repository > Or within the internal Forest Service GitHub instance

A javaScript equivalent can be accessed in the GEE Playground > on GitHub > Or within the Forest Service GitHub instance

Documentation (in progress)

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/gee-community/geeViz) into your Python's site-packages

  6. To stay up to date, upgrade via PIP (pip install geeViz --upgrade) or 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)

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 timeLapseExample
    • from geeViz.examples import getLandsatWrapper
    • from geeViz.examples import getSentinel2Wrapper
    • from geeViz.examples import getCombinedLandsatSentinel2Wrapper
    • from geeViz.examples import harmonicRegressionWrapper
    • from geeViz.examples import LANDTRENDRWrapper
    • from geeViz.examples import LANDTRENDRViz
    • from geeViz.examples import CCDCViz
    • from geeViz.examples import lcmsViewerExample
    • from geeViz.examples import LCMAP_and_LCMS_Viewer
    • from geeViz.examples import phEEnoVizWrapper
    • from geeViz.examples import LANDTRENDRViz
    • from geeViz.examples import GFSTimeLapse

  • These examples are a great way of getting started. In order to use them for your work, go to you Python site-packages folder PythonNN\Lib\site-packages\geeViz

  • There are several notebook eamples also available. These are very similar to their script counterparts, but are better for learning how to use the tool.

  • 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.
