GeoPhilly unites developers, geographers, data geeks, open source enthusiasts, civic hackers and map addicts in our shared love of maps and the stories they tell. If you use maps as part of your work or just want to learn more, this is the meetup for you!
Our events aim to be open, friendly, educational and social and range from happy hours to lightning talks or even workshops. Come create a diverse, inspiring geospatial community in the Philadelphia with us!
This event is co-sponsored by DataPhilly and GeoPhilly. Please RSVP to only one of the meetup groups.
Schedule: 6:00pm: Welcome 6:15 to 8pm: Workshop
Workshop: Geospatial Data Analysis Landcover classification using satellite data (e.g. Landsat8, Sentinel2, etc.) is becoming more and more popular as it is the foundation for many other projects (city planning, farm management, etc.). However, downloading large-sized satellite images (GBs) can be time consuming and requires large memory space. On the other hand, Google Earth Engine Python API provides an easy and fast way to get access to and query satellite data to points of your interest.
In this workshop, we will learn how to use Google Earth Engine Python API to get time-series Sentinel2 data to two groups of points: points in urban area and points in crop lands, and then visualize and compare time-series Sentinel2 spectrums of points in urban areas and crop lands.
If time permits, we will explore how to build up a machine learning model for landcover classification (cropland vs. urban land) using the above time-series data we obtain.
Presenter: Dr. Fei Jiang Dr. Fei Jiang obtained her PhD from the Pennsylvania State University in 2020. Her past research aimed to address water pollution problems from agriculture watersheds in Pennsylvania using a variety of GIS and other geospatial analysis techniques. After that, she joined PlantVillage at Penn State as a GIS and machine learning expert. Together with her wonderful team, she works towards helping millions of smallholder farmers in Africa adapt to climate change and combat pest attacks.
Pre-requisites: Basic python knowledge
All registered attendees are requested to check email or meetup page before workshop for information on downloading any workbooks or open source software.
