Support Vector Machines – on recognizing pixel clusters in satellite data

  • blog
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 »Support Vector Machines – on recognizing pixel clusters in satellite data

Earth Observation: Big Data

  • blog
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

How to consume news/information? If you are not on the first page of a Google search you are effectively nowhere; perhaps if you are not in the first three search results you don’t stand much chance of getting viewed. This presents a problem of trust; we have to trust that the Google search algorithms are… Read More »Keep up to date

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

Commercialisation of space

  • blog
I previously wrote about the Geospatial 2.0 workshop held earlier this year on the Space Campus in Harwell. http://www.acgeospatial.co.uk/blog/geoworkshop/ 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
