Remote Sensing


A look at the growth and the polarity of sentiment of Earth Observation and Remote Sensing since 2008, with Python and Pandas

  • blog

  About 18 months ago I looked at tweets from Twitter containing the phrases Earth Observation or Remote Sensing. Primarily I did this after the first Future EO event that ESA held. You can have a look at the post here: #FutureEO and twitter data mining With the next future EO event this November I… Read More »A look at the growth and the polarity of sentiment of Earth Observation and Remote Sensing since 2008, with Python and Pandas


Scene from above Podcast

Since late last year Alastair Graham and I have been working together on a Podcast. It is something we have both been keen to explore for a while and it certainly felt that the time was right. The aim, at least for me, was to produce something that I would want to listen to. To… Read More »Scene from above Podcast

Blob detection on Satellite Imagery, using OpenCV

  • blog

OpenCV is a fantastic tool for quickly processing satellite data. It is incredibly powerful and very fast. It has also just recently been updated; the full announcement is here. Previously I used Image Segmentation with the Watershed Algorithm to successfully map circular irrigation features using OpenCV. Like many geospatial/image processes (where there are multiple ways… Read More »Blob detection on Satellite Imagery, using OpenCV

The cloudiest place

  • blog

Have you ever wondered what part of the planet is the most cloud free, or perhaps the most cloudy? It is recognised that the biggest impact on optical Remote Sensing is cloud; even if we can acquire an image everyday, we still cannot do much with it if is full of clouds. With the free… Read More »The cloudiest place

Machine learning Landsat / Sentinel data

  • blog

What changes can be measured using Landsat and/or Sentinel-2 data? In large areas change detection (land use for example) is commonly used for these data sets. If companies like Orbital Insights are counting cars, using shadows from floating oil tanks to determine capacity and measuring levels of construction, what smaller objects and data analytics can be… Read More »Machine learning Landsat / Sentinel data

EO data deluge

  • blog

September 2016 was a busy month for the launch of Earth Observation satellites. Terrabella launched 4 more of its SkySats, bringing the total to 7. We’re excited to share the first light images from our four newest high-resolution imaging satellites, SkySat-4-7! — Terra Bella (@terra_bella) September 27, 2016 On the same launch vehicle… Read More »EO data deluge

Commercialisation of space

  • blog

I previously wrote about the Geospatial 2.0 workshop held earlier this year on the Space Campus in Harwell. Ever since this workshop I have started seeing more articles and I have become much more aware of the ‘commercialisation of space’. In April this year The Economist wrote a leader on Space Exploration. machine-learning can… Read More »Commercialisation of space

How low can EO go?

  • blog

The IKONOS satellite, launched in 1999 was the first satellite to offer 1m spatial resolution imagery to the public. It was soon followed by QuickBird; launched in 2001 it provided 60cm imagery. These satellites were, at the time, the workhorses for anyone requiring high resolution imagery. What goes up must come down. #retrospective on #Quickbird… Read More »How low can EO go?

Geospatial 2.0 Workshop

  • blog

“What is the crossing point of machine learning and Earth Observation?” was the question asked this week at the Satellite Applications Catapult Geospatial 2.0 event at the Harwell campus near Oxford. Welcome to everyone attending our Geospatial Workshop today. Perfect clear sky's for Earth Observation! 🌍 — Satellite Applications Catapult (@SatAppsCatapult) July 13,… Read More »Geospatial 2.0 Workshop

Geofencing and Exploration

  • blog

The aim of a seismic survey is to map the subsurface in the most detailed and efficient way, mapping the reservoir so that critical decisions, such as choosing a drilling location, can be made with increased confidence. Definition of the target and an understanding of the quality of data that can be achieved in the… Read More »Geofencing and Exploration
