Digital Soil Mapping

Using R for DSM

Peat Management in Indonesia

We recently published an article in The Conversation on Peat Management and Issues in Indonesia. Sorry in Bahasa Indonesia. But here is an English version of it: Can Indonesian peatland be managed responsibly?

Classical Art as Covariates in Digital Mapping

Cartography is a blend of art and science. But can art be used as covariates in making digital maps? According to a new research yes, and the results are comparable with using real covariates. Ecology mappers face the same problem as DSMers, which covariates should be used for digital mapping?   Machine-learning algorithms supposedly can handle a large number of predictors Read more about Classical Art as Covariates in Digital Mapping[…]

Interpolation

We like to perform interpolation to make a better soil map. When WE do interpolation we want and expect something similar in between the observed points. Musicians also do interpolation, but they want something quite different between the elements. According to Wikipedia, interpolation was done differently according to different genre: Classical Music– an abrupt change Read more about Interpolation[…]

Can Lidar measure peat extent and thickness?

Obviously not, but many in Indonesia were convinced that Lidar is the method for measuring peat extent and thickness. Where does this come from? Lidar, particularly used in airborne mapping, can be used to create a 3-D earth’s surface model. Laser pulses reflect objects both on and above the ground surface, thus it enables estimation Read more about Can Lidar measure peat extent and thickness?[…]

Digital mapping of peatland in West Sumatra

Prof. Dian Fiantis from Universitas Andalas collaborate with us (remotely) to map peatland in West Sumatra, an oil palm plantation with an area about 40,000 hectares. We helped designed the sampling locations by a stratified random approach. Students studied in the Soil Survey Course at Andalas were allocated to groups or zones. They located the Read more about Digital mapping of peatland in West Sumatra[…]

Proximal Soil Sensing from a long way away, and a long time ago

Lunokhod 1 (Луноход, moon walker in Russian) was the first astro-remote-controlled rovers landed on the Moon by the USSR. It was carried to the moon by the Luna 17 spacecraft, landed on November 17, 1970 in the northwestern part of Mare Imbrium, and operated until September 29, 1971. Lunokhod 1 is an eight-wheel rover with Read more about Proximal Soil Sensing from a long way away, and a long time ago[…]

Soil temperature increase in Australia for the past 50 years

Can historical soil temperature data tell us about climate change? Of course Yes, it all began when we visited the Cowra Agricultural Research station and Brian Murphy showed us the soil temperature data from a depth of 1.8 m which was collected daily since 1942. The data show a gradual increase in soil temperature over Read more about Soil temperature increase in Australia for the past 50 years[…]

Best paper 2016: Farm-scale soil carbon auditing

Our paper Farm-scale soil carbon auditing authored by Jaap deGruijter, Alex McBratney, Budiman Minasny, Ichsani Wheeler, brendan Malone and Uta Stockmann was recently voted as Best Paper in Geoderma. The paper available here was published in the March issue of Geoderma. The idea of the paper was borne out of an ARC Linkage project in Read more about Best paper 2016: Farm-scale soil carbon auditing[…]

Open digital mapping for assessing carbon storage in tropical peatlands

Researchers from Sydney, Australia, and Bogor, Indonesia demonstrate that tropical peatland can be mapped accurately and cost effectively using freely-available remote sensing data and open source software. At COP23 in Bonn, the Global Peatlands Initiative and various organisations held events aiming to bring peatlands on the agenda at COP23. Peatlands have an important role in Read more about Open digital mapping for assessing carbon storage in tropical peatlands[…]
