INVESTIGATION OF DEFORESTATION USING MULTI-SENSOR SATELLITE TIME SERIES DATA IN NORTH KOREA [PDF]

open access: yes, 2017
Department of Urban and Environmental Engineering(Environmental Science and Engineering)North Korea is very vulnerable to natural disasters such as floods and landslides due to institutional, technological, and other various reasons. Recently, the damage

MODISTools - downloading and processing MODIS remotely sensed data in R [PDF]

open access: yes, 2014
Remotely sensed data – available at medium to high resolution across global spatial and temporal scales – are a valuable resource for ecologists. In particular, products from NASA's MODerate-resolution Imaging Spectroradiometer (MODIS), providing twice ...

Modelling fire occurrence at regional scale. Does vegetation phenology matter? [PDF]

open access: yes, 2015
Through its influence on biomass production, climate controls fuel availability affecting at the same time fuel moisture and flammability, which are the main determinants for fire ignition and propagation.

Sensitivity of airborne-derived crop stress indices to the agricultural practices [PDF]

open access: yes, 2008
When acquired both in optical and thermal infrared domain, remotely sensed data can provide a wide range of information about the status of a crop. Several studies have demonstrated the utility of such information for the development of stress indices ...

Use of consumer-grade cameras to assess wheat N status and grain yield [PDF]

open access: yes, 2019
Relationships between (a) fractional Intercepted PAR (fIPAR), and (b) aboveground biomass (Biomass) and (c) grain yield at harvest with the Normalized Difference Vegetation Index (NDVI) derived either from a spectroradiometer or a conventional camera at ...

Mapping forests in monsoon Asia with ALOS PALSAR 50-m mosaic images and MODIS imagery in 2010. [PDF]

open access: yes, 2016
Extensive forest changes have occurred in monsoon Asia, substantially affecting climate, carbon cycle and biodiversity. Accurate forest cover maps at fine spatial resolutions are required to qualify and quantify these effects. In this study, an algorithm

Local forest structure variability increases resilience to wildfire in dry western U.S. coniferous forests. [PDF]

open access: yes, 2020
A 'resilient' forest endures disturbance and is likely to persist. Resilience to wildfire may arise from feedback between fire behaviour and forest structure in dry forest systems.

Radiometric normalization of high spatial resolution multi-temporal imagery : A comparison between a relative method and atmospheric correction [PDF]

open access: yes, 2007
Radiometric normalization is a vital stage in the pre-processing of multi-temporal imagery. It aims to insure a reliable exploitation of images acquired under different imaging conditions.

Sensitivity of GNSS-R spaceborne observations to soil moisture and vegetation [PDF]

open access: yes, 2016
Global navigation satellite systems-reflectometry (GNSS-R) is an emerging remote sensing technique that makes use of navigation signals as signals of opportunity in a multistatic radar configuration, with as many transmitters as navigation satellites are

Applying Remote Sensing Technologies in Urban Landscapes of the Mediterranean

open access: yesAgriEngineering, 2020
There has been increasing pressure on water resources in cities due to the proliferation of urban green areas. In the Mediterranean climate, only a small part of the plants’ water needs is supplied by rainfall during the winter months.
