Awesome-EarthObservation-Code

A curated list of awesome tools, tutorials, code, helpful projects, links, stuff about Earth Observation and Geospatial stuff!

This list was started based on #scenefromabove podcast lunchtime discussions

This is being extended frequently in April 2020. Please note that this is not offically an awesome list (yet). Please help me to get it there by contributing and commenting. guidelines

Annotations are based on the headers - where available - on the github accounts

Alastair Graham @ajggeoger and Andrew Cutts @map_andrew come together to present an informal podcast @eoscenefrom looking at the world of modern remote sensing and EO. Fuelled by their passion for all things raster and geospatial, the #scenefromabove podcast aims to be a mix of news, opinion, discussion and interviews.

Training and learning

Deep learning and Machine Learning

  • CNN-Sentinel -Analyzing Sentinel-2 satellite data in Python with Keras (repository of our talks at Minds Mastering Machines 2019 and PyCon 2018)
  • Robin Cole on satellite imagery and deep learning resources - Resources for deep learning with satellite & aerial imagery
  • Image patches - Using a U-Net for image segmentation, blending predicted patches smoothly is a must to please the human eye.
  • Fast AI Satellite imagery resources

  • Road segmentation - Road Detection in satellite imagery. Semantic segmentation is the process of classifying each pixel of an image into distinct classes using deep learning. This aids in identifying regions in an image where certain objects reside.This aim of this project is to identify and segment roads in aerial imagery. Detecting roads can be an important factor in predicting further development of cities, and this concept plays a major role in GeoArchitect (A project which I started). Segmentation of roads is important to map-based applications and is used for finding distances or shortest routes between two places.

Interesting Non EO parts Python

This bit could potentially become the most valuable resource. Lets not ignore other sectors/industries/data science, instead lets embrace it and learn from all that other amazing stuff!

A footnote on awesome

There are many awesome lists relating to 'Geo'. I use that term as widely as possible. This list is not meant to replace these lists. Earth Observation is still way behind the GIS world in terms of audience, reach, number of users etc. Things are changing though, by bringing these links together I hope you can see that there has been so much progress in the last 5 years. I do hope these links are helpful espcially to those who are new to Earth Observation, but also to people like me who with several years of experience think they may have seen it all - we haven't and there is still so much to learn. Earth Observation is not just an academic 'thing' or a basemap anymore, it forms the basis for a growing and diverse business environment. Lets embrace this.

Finally, I wanted to acknowledge a couple of awesome Earth Observation lists that you may list to check out:
