Schweizerisches Landesforstinventar
LFI

Die terrestrischen Aufnahmen im LFI sind sehr aufwändig. Um den Aufwand zu optimieren werden die Stichprobenflächen vor der Feldsaison in Stereoluftbildern interpretiert. Dabei kommen die digitalen Sensordaten der swisstopo zum Einsatz. Eindeutige Nichtwald Flächen werden terrestrisch nicht besucht.

A seamless 3D digital surface model of Switzerland
Switzerland 3D

Every three years swisstopo acquires digital stereo images covering the whole country. The digital sensor ADS80 collects data in the spectral band blue, green, red, near-infrared and pan with ground resolutions between 25 cm and 50 cm. We develop methods and workflows to derive country-wide digital surface models using image correlation techniques.

TreeMig-CH: modelling climate change influenced spatio-temporal forest dynamics in Switzerland
TreeMig-CH: modelling climate change influenced spatio-temporal forest dynamics in Switzerland

In an ensemble study, the forest landscape model TreeMig is applied over Switzerland with various climate change and several land-use-change scenarios to explore the range of forest developments. This project is part of the OcCC/ProClim CH2014 initiative.

TreeMig: modelling spatio-temporal forest dynamics from stand to continental scale
TreeMig

A spatio-temporal forest modelled has been developed to simulate forest dynamics and species migration under a changing climate.

The need for high resolution
Climate data portal

The goal of this project is to provide current and scenario climate grids of resolutions adequate for ecological studies and applications.

BBS: Developing methods to simulate biome boundary shifts
BBS

Tree species migration can considerably slow down biome boundary shifts. We develop methods to simulate migration reliably and efficiently with coarse resolution.

Comparison of methods for interpolating soil properties using limited data
Methods for interpolating soil properties

Spatial interpolation of biological and biophysical variables is of central interest to many landscape ecologists. In this study, scientists evaluated the utility, accuracy, and effectiveness of ordinary kriging, inverse-distance weighting, and thin-plate smoothing splines with tensions using soil samples from the Omo Basin, Ethiopia.

MAIOLICA: Simulation of vegetation emitted greenhouse gases
MAIOLICA

Greenhouse gases emitted from vegetation feed back on the atmospheric chemistry and climate. We aim to simulate such vegetation produced greenhouse gases and to provide information on emissions from other sources.

Spatially-explicit modelling of biophysical parameters for the Shoshone National Forest, WY
Modelling of biophysical parameters

High resolution climate maps were generated for NW-Wyoming (USA) in order to measure tree species realized niches. The goal of this study was to define species parameters for a spatially-explicit, dynamic forest simulation model.

Emerging and Contemporary Technologies in Remote Sensing for Ecosystem Assessment and Change Detection on Military Reservations
Technologies in Remote Sensing

The main objectives of this project were to stratify the landscape of individual military ranges, to identify the fundamental vegetation and soil attributes, to establish ecosystem response and recovery in relation to disturbance (land use), to identify the attributes of remote sensing systems and to develop methods for scaling indices between coarse and fine resolution imagery.
