Displaying 491 - 495 of 661Multi-temporal land-cover classification and change analysis with conditional probability networks: the case of Lesvos Island (Greece)
This study uses a series of Landsat images to map the main land-cover types on the Mediterranean island of Lesvos, Greece. We compare a single-year maximum likelihood classification (MLC) with a multi-temporal maximum likelihood classification (MTMLC) approach, with time-series class labels modelled using a first-order hidden Markov model comprising continuous and discrete variables. A rigorous validation scheme shows statistically significant higher accuracy figures for the multi-temporal approach.
Mapping and monitoring riparian vegetation distribution, structure and composition with regression tree models and post-classification change metrics
Riparian systems have become increasingly susceptible to both natural and human disturbances as cumulative pressures from changing land use and climate alter the hydrological regimes. This article introduces a landscape dynamics monitoring protocol that incorporates riparian structural classes into the land-cover classification scheme and examines riparian change within the context of surrounding land-cover change.
Validation of the collection 5 MODIS FPAR product in a heterogeneous agricultural landscape in arid Uzbekistan using multitemporal RapidEye imagery
The fraction of photosynthetically active radiation (FPAR) absorbed by a vegetation canopy is an important variable for global vegetation modelling and is operationally available from data of the Terra Moderate Resolution Imaging Spectroradiometer (MODIS) satellite sensor starting from the year 2000. Product validation is ongoing and important for constant product improvement, but few studies have investigated the specific accuracy of MODIS FPAR using in situ measurements and none have focused on agricultural areas.
Policy Diffusion and Innovation: Media and Experts in Colorado Recreational Water Rights
Beginning in 1998, an innovation in water rights policy took place in Colorado. This paper analyses the diffusion of the recreational in-channel water right policy innovation among Colorado communities. This research involved in-depth case studies in 12 Colorado communities. Data include interviews, legal and legislative documents, and mass media coverage. These new water rights spread among Colorado communities through two processes. First, experts acted as information entrepreneurs providing both technical and policy information to other communities.
Integrating remotely sensed data, GIS and expert knowledge to update object-based land use/land cover information
Remote-sensing technology provides a powerful means for land use/land cover (LU/LC) monitoring at global and regional scales. However, it is more efficient and effective to combine remote-sensing measurements with a geographic information system (GIS) database and expert knowledge for change updating than to use remote-sensing technology alone. In this article, these different sources of information are integrated in the proposed framework, which is able to provide rapid updating of LU/LC information.
