Support Vector Machines – on recognizing pixel clusters in satellite data

Scikit-learn, the machine learning library built for Python over 10 years ago is an excellent resource for estimating data and can integrate into geospatial workflows. Helpfully, when choosing an estimator, scikit-learn supplies an interactive diagram to choose the best estimator for the job. One of the big things about machine learning is the need to Read more about Support Vector Machines – on recognizing pixel clusters in satellite data[…]

Earth Observation: Big Data

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 about Earth Observation: Big Data[…]

Template matching with Earth Observation Data

Template matching is a useful technique. Some common uses include manufacturing as a part of quality control, a way to navigate a mobile robot, or as a way to detect edges in images. But can techniques such as these be useful for data captured from satellites? I am especially interested here in Optical data, but Read more about Template matching with Earth Observation Data[…]

Machine learning Landsat / Sentinel data

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 about Machine learning Landsat / Sentinel data[…]

Commercialisation of space

I previously wrote about the Geospatial 2.0 workshop held earlier this year on the Space Campus in Harwell. Geospatial 2.0 Workshop 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. Read more about Commercialisation of space[…]
