Remote sensing inversion of soil moisture and analysis of influencing factors in complex cropland environments in karst plateau mountainous areas of Southern China

Geocarto International
Accurate soil moisture assessment is crucial for ecological and agricultural purposes. To investigate the soil moisture distribution and its influencing factors under the mountainous areas of the karst plateau, this study took the cultivated plots as a ...

The Dutch Caribbean municipalities in comparative perspective [PDF]

Island Studies Journal, 2015
Upon the dissolution of the Netherlands Antilles in 2010, the smallest islands in this federation – Bonaire, St. Eustatius, and Saba – became special municipalities of the Netherlands, and were hence politically and constitutionally integrated into the ...

NDVI assessment versus two impact factors analysis (separate analysis based on chlorophyll content and leaf cellular structure): which method is more effective to detect declining health of an individual tree?

Geocarto International, 2023
In detecting the internal health of an individual tree, “two impact factors analysis” refers to evaluation of NIR and RED separately, instead of merging them together in one formula as in NDVI assessment.

Islanders in community: identity negotiation through sites of conflict and transcripts of power [PDF]

Island Studies Journal, 2010
This paper explores the problem of negotiated identity on Madeline Island (Wisconsin, USA). In this social context, who is and who is not an islander is not clearly defined as simply “local” or “tourist”.

Automatic lineaments detection using radar and optical data with an emphasis on geologic and tectonic implications: a case study of Kabul Block, eastern Afghanistan

Geocarto International, 2023
The earth’s surface linear features, expressing geological lineaments, play a key role in identifying hydrothermal alteration and mineralization zones, as well as in understanding tectonic settings of a region.

First evidence of Campanian-Maastrichtian shallow marine deposits from eastern Atlantic margin (Doualasub-basin, Cameroon): Palynological and sedimentological approaches

Geosystems and Geoenvironment
Integration of facies analysis with organic microfossils (mainly dinoflagellate cysts) provides insights into the paleoenvironmental reconstruction of the onshore part of the Douala sub-basin of Cameroon.

A landscape metrics-based sample weighting approach for forecasting land cover change with deep learning models

Geocarto International, 2023
Unaddressed imbalance of multitemporal land cover (LC) data reduces deep learning (DL) model usefulness to forecast changes. To manage geospatial data imbalance, there is a lack of specialized cost-sensitive learning strategies available.

Recontinentalizing Canada: Arctic Ice’s Liquid Modernity and the Imagining of a Canadian Archipelago [PDF]

Island Studies Journal, 2009
Studying mobile actor networks of moving people, objects, images, and discourses, in conjunction with changing time-spaces, offers a unique opportunity to understand important, and yet relatively neglected, “relational material” dynamics of mobility.

Deep learning methods applied to digital elevation models: state of the art

Geocarto International, 2023
Deep Learning (DL) has a wide variety of applications in various thematic domains, including spatial information. Although with limitations, it is also starting to be considered in operations related to Digital Elevation Models (DEMs). This study aims to
