Since warning of the global warming by carbon dioxide, the biomass distribution of forest has been concerned and its study has been requested. Much expectation has focused on the remote sensing corresponding to wide area. We noticed small area and estimated the spatial distribution of the forest volume using the actual GIS and remote sensing data. We comprehended the spatial distribution of the...

Boreal stream networks are embedded in a mosaic of wetlands and lakes interspersed in the forest landscape. This mosaic results in complex and dynamic water chemistry that varies depending on stream size, catchment characteristics, season and flow. Spatiotemporal variations in stream acidity are however frequently predictable based on spatial patterns in the terrestrial watershed, and acidity h...

a widespread approach from which managers were able to ‘determine objective policing tactics in regard to enforcement targets, prevention activities and further intelligence gathering operations’ (Ratcliffe, 2008, p1). Unfortunately, as Hammersley (2008) points out, drug issues can be complex, as they exist within a multifaceted, multitiered global Introduction In 1993, the Audit Commission set...

This paper presents an approach to perform geo-referenced estimations of forest wood residues availability for energy use based on forest inventory data integration into a GIS. Three different estimation methods are described. The first one evaluates biomass availability based on the application of biomass expansion factors to stem volume data of the forest inventories. The method accounts for ...

There has been much research over the past decade on aspects of bus-transit-system service and performance. Common to studies is the necessity that the population served by systems be estimated. Usually this entails delineating areas for which demand is covered through the use of geographic information systems (GIS), as well as deciding on how best to represent potential ridership spatially. Ho...

Forest roads and permanent fuelbreaks are an important part of fire suppression infrastructure, but due to maintenance and environmental costs many forest agencies seek to reduce the extent of these networks. The question of which roads should be retained or where fuelbreaks should be established is contentious, and few quantified methods exist to aid management decisions. This study uses GIS p...

Spatio-temporal land cover changes witnessed within the Nyando River Basin of Kenya were assessed in this study. The land cover changes were mapped by classifying the predominant land cover classes on selected Landsat satellite images. The accuracy of the classifications were assessed using reference datasets developed and processed in a GIS with the help ground based information obtained throu...
