A semi-automatic methodology to detect fire scars in shrubs and evergreen forests with Landsat MSS time series

This paper presents a semi-automatic methodology for fire scars mapping from a long time series of remote sensing data. Approximately, a hundred MSS images from diFerent Landsat satellites were employed over an area of 32 100 km in the north-east of the Iberian Peninsula. The analysed period was from 1975 to 1993. Results are a map series of fire history and frequencies. Omission errors are 23%...

Semi-Automatic Detection of Storm-Felled Forest Areas in Western Norway’s Spruce Forests Using a Landsat Time Series and Change Detection

Within the widely investigated field of forest disturbance monitoring, the detection of forest storm damages with remote sensing techniques gained rather low attention in the last years. This work aims to fill this gap. The project of storm damage detection, focusing on spruce forests, was initiated by the Norwegian Forest and Landscape Institute ‘Skog og Landskap’. The triggering event for thi...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
