Data fusion and analysis of maps and remote sensing data collected from different spatial perspectives (ground, air, and space) at different times from the early 20th century to the present using different sensors were used to answer questions about glacier behavior and rapidly changing landscapes of Alaska’s southern Kenai Mountains. Expeditions to three fiords of the southern Kenai Mountains were conducted during the summers of 2004, 2005, 2006, and 2021. Each expedition used repeat photography to document glacier behavior and change, and landscape evolution at six Kenai Mountains glaciers, most located within Kenai Fjords National Park. Bear Glacier, Aialik Glacier, Pedersen Glacier, Holgate Glacier, Little Holgate Glacier, and Northwestern Glacier were studied and at a minimum, their terminus positions were determined for the following dates: 1909, 1950, 1961, 1973, 1990, 2004-2006, and 2021. Each glacier displayed unique asynchronous behavior. Since 1909, all displayed long-term terminus retreat. However, the timing for each glacier was unique. In 2021, Holgate Glacier was advancing, while the other five glaciers were retreating.

Eurasian Black Vulture (EBV) and Eurasian Griffon Vulture (EGV), while residents elsewhere, winter in Uttar Pradesh, India. Knowledge of the habitat and regulating factors is obligatory for protection and better management of these vultures. Therefore, different types of habitats were mapped using eight species distribution models. Presence records from field survey, published data and citizen science, and 23 bioenvironmental raster layers were the model inputs. Eighteen models were developed whose strength varied greatly. As per the performance indicators, GBM and GLM were found to be superior models for EGV. For EBV all models were acceptable. MARS, with good model strength, was rejected on the grounds of field verification. However, the Ensemble model, overall, was found the best. As per this model, good habitat was restricted mostly in the Tarai ecozone. The top two vital variables were NDVI, and bio13 for both the vultures. The most vital temperature variable for EGV was bio08 while bio09 for EBV. Tarai ecozone showed the largest expanse of suitable area for both the vultures followed by Vindhyan-Bundelkhand, Gangetic plains and Semi-arid ecozones. Among the two, EBV (49000 km2) had more suitable area than EGV (37000 km2). Agricultural areas were found to be largely unsuitable. As per land cover, good habitat was mostly confined in forests. For better management of these wintering vultures which need only roosting and foraging, it is proposed that destruction of forested habitat and decrease in foraging materials needed immediate attention and control.

The use of remote sensing indices in order to obtain information for vegetation distributions, heath and patterns is a popular practice with applicability at different scales of detail. The present article presents an example of using the Normalized Difference Vegetation Index (NDVI) and Change Detection method to identify the spatio temporal evolution of forest area in Târgu Lăpuș city, northern Transylvania, Romania. NDVI method is applied at different NDVI threshold values such as 0.1, 0.15, 0.3, 0.45 and 0.6. For the analyzed area, an area of 1.56 km2 with forest gain and 3.59 km2 with forest loss was identified. The advantage of using this method is the large time gap for which it can be done, in our situation being an analysis for the period 1983-2020 so that we can identify the trend of evolution of areas occupied by forests in a city where spatially built it often extends uncontrollably, affecting the degree of compactness of the forests and implicitly their protection functions.

Typically, in scientific publications, peer review processes are used to maintain the quality standards of the research activity and its results presented in manuscripts submitted for publication, to improve performance, relevance and give them credibility. The peer review helps the publisher (editor-in-chief and editors, respectively the editorial board) decide whether the submissions should be accepted, considered acceptable with revisions (minor or major), or rejected. For many journals, all manuscripts submitted are subjected to a double-blind peer-review process, in which the authors and reviewers’ identities are kept secret from each other. The goal of double-blind peer review is for submitted papers to be judged on their scientific merit alone, and thus reducing publication bias (minimizing bias) and protecting identities. The double-blind peer-review model implies that the author's name and affiliation are not revealed to reviewers, and, in turn, the reviewers' name or any other information is never disclosed to the author or other reviewers of the manuscript. In order to ensure the quality of the publications, editors require that the reviewers have expert knowledge in their fields of research and have authored a substantial number of peer-reviewed publications. The selection of reviewers is the responsibility of the editor-in-chief, the editors and the editorial board, respectively.

Geodesy is the science of measuring and representing the earth, whose beginnings are ancient and are found in antiquity. Like other disciplines, it has known a continuous evolution, along with the evolution of human society and the development of knowledge. More than in other sciences, the evolution of geodesy has been dramatically influenced by advances in science and technology. Thus, at present, modern technology has been reached that allows in-depth studies with the help of state-of-the-art technologies, such as radio telescopes, ground surveys, satellites, etc. In Romania, geodetic education and research have a rich history and tradition, but going through numerous and profound restructuring, intensified in the modern era. These were imposed both by the development of science and technology in the field and by economic and social restructuring at the national level. The turmoil and evolutions from the end of the 20th century and the beginning of the 21st century slowly led to the consolidation of the Romanian geodesy and its directions in academic education and research. Ineluctable, things are evolving, and the above issues are being considered by teaching staff and researchers at the universities, research institutes and state and private companies and units with concerns and interests in geodesy. An enthusiastic group of representatives (coming especially from the most recognized universities in Romania, with study programs of land measurements and cadastre) set out to found the new journal Nova Geodesia. After an exhaustive analyzing of the situation of the field in Romania in the current European and international context, they considered that such a journal is timely and necessary in order to support the research in the domain in Romania, but also in the south-eastern part of Europe (facing similar problems) and around the world, truly considering research and creative innovation as the ‘engine of progress’ of humanity. Nova Geodesia has set out to be an open access journal, set up to develop a reliable platform and provide unrestricted access to the scientific literature for the rapid dissemination of recent updates in geodesy and related topics related to cartography, urban administration and the environment, project design and constructions such as dams, bridges, plants, boundary marking, landscape and ecology, environmental management, geography, planetology, hydrography. Through its new approach, the journal adheres to the mission of developing a reliable bridge of communication between people interested in the topics of science and technology mentioned, bringing authentic and unique scientific contributions.
