Earth Engine Tutorial #36: How to find out the greenest day of the year for each location
Open Geospatial Solutions
by Qiusheng Wu
6M ago
This tutorial shows you how to find out the greenest day of the year for each pixel location. The method can be generalized to find out the corresponding time of the maximum value of a timeseries for each pixel, such as the day with the hottest temperature record for each location during the past decades, the day with the largest amount of rainfall for each location during the past year. Requirements geemap - A Python package for interactive mapping with Google Earth Engine, ipyleaflet, and ipywidgets Installation conda create -n gee python conda activate gee conda install mamba -c conda-fo ..read more

Earth Engine Tutorial #34: Interactive extraction of pixel values and interactive region reduction
Open Geospatial Solutions
by Qiusheng Wu
6M ago
This tutorial shows you how to extract pixel values from Earth Engine images interactively and save pixel values as a csv and shapefile. It will also show you how to perform interactive region reduction, which allows users to draw a rectangle or circle to compute descriptive statistics (e.g., mean, min, max, std, sum) of pixels within a user-drawn geometry. The region reduction results can be exported as a csv for shapefile. Requirements geemap - A Python package for interactive mapping with Google Earth Engine, ipyleaflet, and ipywidgets Installation conda create -n gee python=3.7 conda ac ..read more

Earth Engine Tutorial #31: Machine Learning with Earth Engine - Unsupervised Classification
Open Geospatial Solutions
by Qiusheng Wu
6M ago
This tutorial shows you how to perform unsupervised classification (e.g., KMeans clustering) in Earth Engine. Unsupervised classification algorithms available in Earth Engine Source: https://developers.google.com/earth-engine/clustering The ee.Clusterer package handles unsupervised classification (or clustering) in Earth Engine. These algorithms are currently based on the algorithms with the same name in Weka. More details about each Clusterer are available in the reference docs in the Code Editor. Clusterers are used in the same manner as classifiers in Earth Engine. The general workflow for ..read more
