IDENTIFICATION OF LOW ACCURACY REGIONS IN LAND COVER MAPS USING UNCERTAINTY MEASURES AND CLASSIFICATION CONFIDENCE
Multispectral images Classification Uncertainty Confidence Accuracy Spatial variation
2018/11/9
The aim of this article is to assess if the data provided by soft classifiers and uncertainty measures can be used to identify regions with different levels of accuracy in a classified image. To this ...
Study finds mercury levels in Arctic soils 5 times higher than temperate regions
mercury levels Arctic soils 5 times higher temperate regions
2017/7/24
Plants and soil in the Arctic tundra absorb and store mercury released into the atmosphere by industry and mining in the Earth's temperate regions, leading to soil mercury levels five times higher tha...

A NEW METHOD TO DETECT REGIONS ENDANGERED BY HIGH WIND SPEEDS
Non-Parametric Regression Boosted Regression Trees Wind Speeds Spatial Predictions
2016/11/30
In this study we evaluate whether the methodology of Boosted Regression Trees (BRT) suits for accurately predicting maximum wind speeds. As predictors a broad set of parameters derived from a Digital ...

In this study object-based image analysis (OBIA) techniques were applied to assess land cover changes related to mineral extraction in a conflict-affected area of the eastern Democratic Republic of th...
MEASURING POLYCENTRICITY OF MEGA-CITY REGIONS IN CHINA BASED ON THE INTERCITY MIGRATION FLOWS
Migration Flows Mega-city Region Polycentricity Chinese City Social Media Data
2016/11/15
This paper uses the intercity migration flows to examine relations between Chinese cities, identify the important mega-city regions and measure each region's polycentricity from an interaction perspec...

Remote Sensing Ocean
2016/7/28
It is well known that Internal Waves of tidal frequency (i.e. Internal Tides) are successfully detected in sea‐surface height (SSH) by satellite altimetry (Ray and Mitchum, 1996). Shorter period Inter...
Much research has been devoted to studies of and algorithms for memory management based on garbage collection or explicit allocation and deallocation. An alternative approach, region-based memory mana...
Region-based memory management systems structure memory by grouping objects in regions under program control.Memory is reclaimed by deleting regions, freeing all objects stored therein. Our compiler f...
