A visualization of map error presented in the journal article 'Spatial cross-validation is not the right way to evaluate map accuracy.'

There are different ways to evaluate map accuracy, and ISRIC pedometrician and senior researcher Gerard Heuvelink recently gave a talk on what he considers to be the gold standard of soil map accuracy assessments: design-based probability sampling.

Soil spectroscopy is a rapidly growing field of research used to measure soil properties and generate soil data. Along with the increased use of soil spectroscopy, sound and standardised procedures are needed for soil spectral measurements, analysis, storage, exchange and prediction of soil properties.

We were saddened to hear of the passing of our former colleague, Mr Wout Bomer. While at ISRIC (1979 – 2010), he worked with great dedication in various capacities providing support with respect to documenting our soil monolith collection, digitization of the slide collection, as well as being our graphic designer and photographer. Wout also ensured that records documenting ISRIC events were properly archived, thereby preserving the institutional ‘memory’ of our institute.

Forests cover approximately 35 percent of Europe, provide employment for 3.5 million people, generate € 500 billion revenue annually and absorb about 10 percent of Europe's annual greenhouse gas emissions. Sustainably managing forest soils, which underpin these key forest benefits, is key to caring for these important ecosystems.
