The georeferencing of RASAT satellite imagery and some practical approaches to increase the georeferencing accuracy

open access: yesGeocarto International, 2015
RASAT Earth Observation Satellite is the second remote sensing satellite of The Scientific and Technological Research Council of Turkey (TUBITAK) Space Technologies Search Institute (TUBITAK Space). Generally, the first step to utilize the satellite imagery in GIS applications is the accurate geometric correction of the imagery.

Evaluating UAV captured RGB and multispectral imagery as a proxy for visual rating of leaf spot in cultivated peanut

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Leaf spot is a devastating disease in cultivated peanut (Arachis hypogaea L.) that can lead to significant yield losses without chemical controls. Multiple disease symptoms, two causal organisms, inconsistent testing environments, and genotype by environment interactions are all components that make breeding for leaf spot‐resistant peanuts ...

Deep learning‐based high‐throughput detection of flowered maize (Zea mays L.) plots from UAS imagery across environments

open access: yesThe Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Flowering time is a critical phenological trait in maize (Zea mays L.) breeding programs. Traditional measurements for assessing flowering time involve semi‐subjective and labor‐intensive manual observation, limiting the scale and efficiency of genetics and breeding improvement.

Georeferencing Brazilian Highway Addresses

open access: yesJournal of Geographic Information System, 2016
The usage of georeferencing as a search tool has suffered a massification after the diffusion of technologies developed by Google and Microsoft. In this context, problems related to the location of properties situated on highways are becoming quite usual in Brazil, because properties registration in highway is permitted in the country and this ...

Species Distribution Modeling of Killer Whales (Orcinus orca) in Australian Waters

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
In this study, we model the spatial distribution of killer whales in Australian waters using MaxEnt. The presence‐only SDMs identified potential areas of habitat suitability and conservation priority both within and outside of known locations. Moreover, the importance of certain predictor variables indicated a preference for different environmental ...

Automated identification of river hydromorphological features using UAV high resolution aerial imagery [PDF]

open access: yes, 2015
European legislation is driving the development of methods for river ecosystem protection in light of concerns over water quality and ecology. Key to their success is the accurate and rapid characterisation of physical features (i.e., hydromorphology ...

From Herbarium to Landscape: New Records and Mapping Rare and Threatened Species of Brazilian Atlantic Rainforest

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Botanical collections remain limited in the mountainous areas of the Brazilian Atlantic Rainforest, which compromises biogeographic knowledge of endangered and locally endemic species and many others that have not yet been described. These gaps hinder the accuracy of biodiversity indicators, limit the discovery and description of new species, restrict ...
