2014/5/6
NOAA-AVHRR bi-monthly NDVI data of 8×8 km for the period of 1982–2006 were used to analyze the trend of crop phenology matrices over Indian region. Time series principal component analysis of NDVI was...
OBJECT-BASED APPROACH TO MAP SEMI–NATURAL AREAS IN MOUNTAIN REGION WITH HIGH SPATIAL RESOLUTION IMAGES
Object-based texture measurements data mining decision tree semi-natural areas
2014/6/12
Semi–natural areas are characterized by cultivated and natural areas with continuous transition zones. Especially in the alpine regions, this type of land-cover is predominant. The paper presents a me...

2014/6/12
In Portugal, updating municipal plans (1:10 000) isrequired every ten years. High spatial resolution imagery has shown its potential for detailed urban land cover mapping at large scales. However, sha...
SUPER-RESOLUTION MAPPING OF LANDSCAPE OBJECTS FROM COARSE SPATIAL RESOLUTION IMAGERY
Super-resolution mapping coarse spatial resolution image landscape patches characterization
2014/6/12
The landscape patches that are fundamental to landscape ecology may be considered as objects to be extracted from remotely sensed imagery. The accuracy with which objects may be characterised varies ...
SPATIAL ACCURACY ASSESSMENTOF OBJECT BOUNDARIES FOR OBJECT-BASED IMAGE ANALYSIS
Uncertainty object-based accuracy assessment object fate object validity
2014/6/12
Before an object-based image classification can be used, one has to evaluate if it qualifies for its designated purpose, because uncertainty occurs in the complex process of object-based image analysi...
