This blog is loosely a transcipt from the scenefromabove podcast season 12 episode 6. You can listen to it below. These, though, are my opinions. Background When we started doing the podcast in Dec 2017 we were raving about Google Earth Engine (GEE) and if you’d asked me what Microsoft were doing in the Earth… Read More »GEE vs Planetary Computer
Google Earth Engine seems to be updated pretty frequently. Towards the end of 2018, I noticed two interesting things – that some of the Sentinel 5P data is now available and that Google is shutting down Fusion Tables. Fusion Tables will be shut down at the start of December 2019, so you have just under… Read More »Google Earth Engine: Sentinel 5P, and the demise of Fusion Tables
Almost a year ago I wrote a post on building time-lapse imagery with Google Earth Engine. It shows how to process the Landsat 8 top of atmosphere collection into an mp4 format. It talks about choosing the path and row and filtering on clouds, selecting the bands and converting to 8 bit imagery. I did… Read More »Time series on Landsat data with Google Earth Engine
Google Earth Engine (GEE) has a very nice feature called ‘image reducer’ and, frankly, it is incredibly useful. Say, for example, you have a field boundary and you want to know the mean, median, maximum and minimum NDVI values for it. In GEE you can use the reducer to get these values. You can also… Read More »Image reducer in Python
If you have an hour (or 3) to spare then there are certainly worse things to do than to investigate the last 30 or so years of time-lapsed imagery on Google Earth Engine Timelapse. It can make for uncomfortable viewing as ice retreats or urban areas expand at a phenomenal rate. It can inform you;… Read More »Building time-lapse imagery with Google Earth Engine
This week I saw an excellent overview of Google Earth Engine Google Earth Engine docs I’ve previously written about Google Earth Engine here. If you want a basic guide, take a look. http://www.acgeospatial.co.uk/blog/processing-google-cloud/ It is worth repeating from my previous article, “You can sign up / request access here https://earthengine.google.com/ As long as you are… Read More »5 Awesome things about Google Earth Engine
October 2016 brought the announcement from Google that it had all Landsat and Sentinel data on its cloud. Amazon are also hosting all this data, ESRI are using the Amazon cloud and so are Planet (both of these for over a year). Never before has so much Earth Observation data been available to everyone. I… Read More »Processing images on the Google Cloud
The Great Britain and Northern Island cycling team are good. In fact, they are very good. In Bejing 2008 they won 8 golds, 4 silver and 2 bronze (14 medals; 2nd place France with 6 medals) In London 2012 they won 8 golds, 2 silver and 2 bronze (12 medals, 2nd place Germany with 6… Read More »Marginal gains in EO – Google goes for timelapse
