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
This week Planet successfully launched 88 of its doves, taking another massive step forward in mapping the entire planet daily. I have written about the dramatic increase in temporal resolution data several times in the past. It is worth repeating though – I think – that while Remote Sensing is not new, the level of… Read More »Data, data everywhere
What is Big Data? Big data is a term for data sets that are so large or complex that traditional data processing application softwares are inadequate to deal with them. https://en.wikipedia.org/wiki/Big_data In an event this week in central London I heard big data described as “non-spreadsheet” data. I think Earth Observation (EO) data could fit… Read More »Earth Observation: Big Data
I have previously written about automatically edge detecting. Using OpenCV is a nice way of quickly running the edge detect and getting some information back about the image. You can read about the Canny edge detection algorithm here Here is how Wikipedia details the process of the canny edge detection (if you didn’t click the… Read More »Reclassify and Numpy
Last week I attended the ESRI Petroleum user group in London. I think just over 200 people attended. I missed last year’s event but I have been present at this regular event many times in the past. Many thanks to the organisers – they do an incredible job. Pleasingly, there were plenty of Earth Observation… Read More »GIS Petroleum User Group
This week I attended “Geo-Tech Masterclass: Introduction to satellite APIs” given by Planet (formally Planet Labs) at the Geovation hub in London. The Geovation hub is run by the Ordnance Survey with the “intention to be a centre of collaboration and inspiration in the UK geospatial industry” – exciting times! Earth Observation data can be… Read More »Temporal EO (Planet and the Oilfield)
