Presentation Abstract

Earth Engine is a free cloud computing platform with a multi-petabyte catalog of satellite imagery and geospatial datasets. During the past few years, Earth Engine has become very popular in the geospatial community and it has been used for numerous environmental applications at local, regional, and global scales. In this hands-on presentation, I will demonstrate how to use Earth Engine and the geemap Python package for large-scale geospatial analysis, using automated surface water mapping as a case study. I will introduce a general workflow that is applicable to many environmental applications, such as large-scale vegetation mapping, urban mapping, and land cover change analysis. Some of the key steps of the workflow include: defining study area, searching GEE data catalog, filtering image collection, creating timelapse animations, developing algorithms, applying algorithms to timeseries images, visualizing results, and batch-exporting datasets. I highly recommend you install the geemap Python package before this webinar so that you can follow me to execute code interactively in Jupyter notebook during the webinar.
