Automated detection of individual clove trees for yield quantification in northeastern Madagascar based on multi-spectral satellite data

Autor: Sandra I.B. Roth, Reik Leiterer, Michael E. Schaepman, Enrico Celio, Michele Volpi, Philip C. Joerg

Publikováno v: Remote Sensing of Environment, 221

There is an increasing demand for clove products, mainly dried buds and essential oil on global markets. Consequently, the importance of clove trees as a provisioning service is increasing at the local level, particularly for smallholders cultivating

Capturing and quantifying the world in three dimensions (x,y,z) using light detection and ranging (lidar) technology drives fundamental advances in the Earth and Ecological Sciences (EES). However, additional lidar dimensions offer the possibility to

Vegetation monitoring in refugee-hosting areas in South Sudan

Autor: Reik Leiterer, Sebastian Eugster, Philip C. Joerg, Hendrik Wulf, Urs Bloesch

Mass population displacements put additional stress on the ecosystems and often lead to conflicts with the host communities, especially in the case of large refugee or Internally Displaced Person (IDP) camps. Therefore, there is need for the assessme

Computation of a distributed glacier surface albedo proxy using airborne laser scanning intensity data and in-situ spectro-radiometric measurements

Autor: Philip C. Joerg, Michael E. Schaepman, Michael Zemp, Jorg Weyermann, Felix Morsdorf

Publikováno v: Remote Sensing of Environment. 160:31-42

In recent years, multi-temporal topographic measurements from airborne laser scanning (ALS) have been increasingly used as a source of spatially explicit and accurate information to calculate geodetic glacier mass balances. Simultaneous to collecting

Evaluating volumetric glacier change methods using airborne laser scanning data

Autor: Michael Zemp, Philip C. Joerg

Publikováno v: Geografiska Annaler: Series A, Physical Geography. 96:135-145

Assessments of geodetic volume change are widely used in glaciology and have a long tradition dating back to the nineteenth century. Over time, the geodetic method and corresponding data storage have been developed further, but the resulting methodol

High uncertainty in 21st century runoff projections from glacierized basins

Autor: Matthias Huss, Philip C. Joerg, Nadine Salzmann, Michael Zemp

Publikováno v: Journal of Hydrology. 510:35-48

Glacier response to a changing climate and its impact on runoff is understood in general terms, but model-based projections are affected by considerable uncertainties. They originate from the driving cli- mate model, input data quality, and simplific

Glacier-wide mass balance has been measured for more than sixty years and is widely used as an indicator of climate change and to assess the glacier contribution to runoff and sea level rise. Until recently, comprehensive uncertainty assessments have

Methodological approaches to infer end-of-winter snow distribution on alpine glaciers

Autor: Michael Zemp, Martin Hoelzle, Leo Sold, Philip C. Joerg, Matthias Huss, Hubert Andereggen

Publikováno v: Journal of Glaciology

Snow accumulation is an important component of the mass balance of alpine glaciers. To improve our understanding of the processes related to accumulation and their representation in state-of-the-art mass-balance models, extensive field measurements a
