The final web-app using Greppo and GEE. Image by author. Google Earth Engine is an amazing tool in a data scientists toolbox for working with geospatial data. However, building a web-app with the GEE code editor requires a steep learning curve. The JavaScript based app-creator requires a large investment of time for data scientists who are solely Python developers Greppo is the perfect tool to bridge this gap. In this blog post I will be building a web-application with Greppo with a a popular GEE use-case with DEM (Digital Elevation Model). I will walk you through understanding the basics of GEE, the client-server model, how the API works and the GEE data model. With that background, the post will use Greppo to create an app using GEE’s Python interface and highlight Greppo’s mental model and easy to use interface. Note: All the code here is in Python. They are ported from the GEE’s sample JavaScript code in the documentation . Getting started Before we get started, you need to get access to Google Earth Engine. Follow the instruction Here is a quick tutorial on Greppo and how to use it: Build a geospatial dashboard in Python using Greppo Next, let’s setup our Python environment to install the dependencies. To understand what Python environments are and how to set it up, pip install earthengine-api greppo The code for the web-app will go into app.py, and the app is served and run through the command line using the command greppo serve app.py. Note: To run the greppo comman...

For an introductory look at JavaScript and more in-depth exercises with the Earth Engine API, see Google Earth Engine allows users to run algorithms on georeferenced imagery and vectors stored on Google's infrastructure. The Google Earth Engine API provides a library of functions which may be applied to data for display and analysis. Earth Engine's How to use these docs The Earth Engine documentation is designed for people familiar with geospatial data analysis. The docs are primarily structured by data type. For example, the left side navigation contains links to sections or pages about important data types such as Image, ImageCollection, Feature, FeatureCollection, G...

We’re at a unique inflection point in our relationship with the planet. We face existential climate threats — a growing crisis already manifesting in extreme weather events, coupled with the loss of nature resulting from human activities such as deforestation. But at the same time, the world is mobilizing around climate action. Citizens are demanding progress, and governments and companies are making unprecedented commitments to transform how we live on this planet — from policy decisions to business practices. Over the years, one of the top climate challenges I’ve heard from businesses, governments and organizations is that they’re drowning in data but thirsty for insights. So starting today, we’re making Google Earth Engine, which originally Earth Engine will be Earth Engine will also be available to startups that are a part of the For organizations that may not have resources dedicated to working with Earth Engine, we’ve continued to grow our partner network to support them. For example, our partner NGIS worked with Rainforest Trust to get action-oriented and tailored insights that can help them conserve 39 million acres of tropical forests around the world.

Earth Engine Explorer (EE Explorer) is a lightweight geospatial image data viewer with access to a large set of global and regional datasets available in the This tutorial will cover the use of the EE Explorer application, including: • how to find data in the Data Catalog • adding data to the Workspace • explanation of interface features • how to tailor data visualization The goals of this tutorial are to enable you to use EE Explorer, inspire you to discover and view new data, and provide a starting point to imagine how you might expand your exploration using the Tutorial Contents • Earth Engine Explorer • Data Catalog • Workspace • Managing Data Layers • Adding data layers • Layer visibility • Adjusting data layer date • Adding multiple layers • Duplicate datasets • Reordering layers • Removing layers • Setting visualization parameters • Data band display • Single-band grayscale • Three-band true color • Three-band false color • Contrast, brightness, and opacity • Data range • Gamma • Opacity • Palette • Visualizing change over time • Things to look out for • What's Next • Feedback for us? Data Catalog The Data Catalog lists the datasets available for viewing and analysis in Earth Engine proper. A subset of the data are available for display in EE Explorer. • Click on the Data Catalog button in the upper right of the EE Explorer app. On the Data Catalog page you will see a list of Popular Tags, linking to datasets that have those tags applied. Below that is a list of var...

Meet Earth Engine Google Earth Engine combines a multi-petabyte catalog of satellite imagery and geospatial datasets with planetary-scale analysis capabilities. Scientists, researchers, and developers use Earth Engine to detect changes, map trends, and quantify differences on the Earth's surface. Earth Engine is now available for commercial use, and remains free for academic and research use. Simple, yet powerful API The Earth Engine API is available in Python and JavaScript, making it easy to harness the power of Google’s cloud for your own geospatial analysis. Google Earth Engine has made it possible for the first time in history to rapidly and accurately process vast amounts of satellite imagery, identifying where and when tree cover change has occurred at high resolution. Global Forest Watch would not exist without it. For those who care about the future of the planet Google Earth Engine is a great blessing! -Dr. Andrew Steer, President and CEO of the World Resources Institute.
