The Balearic coastline presents an environmental and biological heterogeneity, which confers great complexity on the marine environment and treasures important biodiversity, both at the level of ...species and marine communities. The endemic phanerogam of the Mediterranean Sea, Posidonia oceanica, holds a pivotal role in maintaining high biodiversity, warranting protection as stipulated in the Posidonia Decree 25/2018. The purpose of this study is to provide quantitative criteria that will allow the delimitation of areas with Posidonia oceanica for conservation and to aid planning and management of this species, contributing to the reduction of biodiversity loss caused by anthropogenic impacts and global change. Utilizing a comprehensive approach, the study employs photo interpretation of aerial photographs taken at depths between 0 and 5 m, data from Side-Scan Sonar (SSS) campaigns, reprocessing information from the LIFE Posidonia project at depths between 20 and 30 m, and targeted sampling using Remote Operated Vehicles (ROV) and ocular recognition at strategic points. The research not only seeks to assess the present state of the phanerogam but also analyzes its evolution, establishing a technological database for consultation and integrated analysis. This database facilitates effective management by tracking habitat changes, representing a significant contribution to the understanding of the impact of global change on ecosystems through Geographical Information Technologies (TIGs).
Deep maps are finely detailed, multimedia depictions of a place and the people, buildings, objects, flora, and fauna that exist within it and which are inseparable from the activities of everyday ...life. These depictions may encompass the beliefs, desires, hopes, and fears of residents and help show what ties one place to another. A deep map is a way to engage evidence within its spatio-temporal context and to provide a platform for a spatially-embedded argument. The essays in this book investigate deep mapping and the spatial narratives that stem from it. The authors come from a variety of disciplines: history, religious studies, geography and geographic information science, and computer science. Each applies the concepts of space, time, and place to problems central to an understanding of society and culture, employing deep maps to reveal the confluence of actions and evidence and to trace paths of intellectual exploration by making use of a new creative space that is visual, structurally open, multi-media, and multi-layered.
The book presents and discusses a large corpus of Jewish maps of the Holy Land that were drawn by Jewish scholars from the 11th to the 20th century, and thus fills a significant lacuna both in the ...history of cartography and in Jewish studies. The maps depict the biblical borders of the Holy Land, the allotments of the tribes, and the forty years of wanderings in the desert. Most of these maps are in Hebrew although there are several in Yiddish, Ladino and in European languages. The book focuses on four aspects: it presents an up-to-date corpus of known maps of various types and genres; it suggests a classification of these maps according to their source, shape and content; it presents and analyses the main topics that were depicted in the maps; and it puts the maps in their historical and cultural contexts, both within the Jewish world and the sphere of European cartography of their time. The book is an innovative contribution to the fields of history of cartography and Jewish studies. It is written for both professional readers and the general public. The Hebrew edition (2014), won the Izhak Ben-Zvi Prize.
Since the 1980s, ‘critical cartography’ has been developing. Its merits lie in its awareness of the socially constructed nature of cartographic representations, the power relations involved, and the ...process-bound nature of cartographic practices. The ‘post-critical’ cartography proposed here takes up these merits but does so without following the categorical rejection of positivist ‘traditional’ cartography or the moral demarcation of what can and cannot be represented as well as the subordination of theories to the ‘critical’ paradigm. Instead, the ‘post-critical’ approach relies on the struggle for suitable theoretical frameworks—the normative reference horizon within the endeavor of cartography is the enhancement of life chances. In this respect, the prefix ‘post’ refers not only to a temporal ‘after’, but also to the perpetuation of central concerns of ‘critical’ cartography, simultaneously freeing it from such limitations.
Abstract
SLAM is a fundamental problem in robotic field and there have been many techniques on it. It is necessary to give an insight on weakness and strength of these techniques specific to the ...intended final application. This paper presents a study of three most common laser-based 2D SLAM techniques: Gmapping, KartoSLAM and Cartographer. Each technique was applied to construct maps combined with autonomous exploration. All the approaches have been evaluated and compared in terms of inaccuracy of constructed maps against the ground truth. In order to draw conclusions on the performance of the tested techniques, a metrics of average distance to the nearest neighbor (ADNN) was applied. Moreover, the computational load of each technique is examined.

"The digital era has brought about huge transformations in the map itself, which to date have been largely conceptualised in spatial terms. Novel objects, forms, processes and approaches have emerged ...and pose new, pressing questions about the temporality of digital maps and contemporary mapping practices: in spite of its implicit spatiality, digital mapping is strongly grounded in time. This collection brings time back into the map, taking up Doreen Massey's critical concern for 'ongoing stories' in the world; it asks how mapping enrols time into these narratives. Maps often seek to ‘freeze’ and ‘fix’ the world, looking to represent, document or capture dynamic phenomena. This collection examines how these processes are impacted by digital cartographic technologies that, arguably, have disrupted our understanding of time as much as they have provided coherence. The book consists of twelve chapters from experts in the field. Each addresses a different type of digital mapping practice and analyses it in relation to temporality. Cases discussed range from locative art projects, OpenStreetMap mapping parties, sensory mapping, Google Street View, to visual mapping, smart city dashboards and crisis mapping. Authors from different disciplinary positions consider how a temporal lens might focus attention on different aspects of digital mapping. This kaleidoscopic approach demonstrates a rich plethora of ways for understanding the temporal modes of digital mapping and the interdisciplinary background of the authors allows multiple positions to be developed and contrasted."
There's no excuse for getting lost these days—satellite maps on our computers can chart our journey in detail and electronics on our car dashboards instruct us which way to turn. But there was a time ...when the varied landscape of North America was largely undocumented, and expeditions like that of Lewis and Clark set out to map its expanse. As John Rennie Short argues in Cartographic Encounters, that mapping of the New World was only possible due to a unique relationship between the indigenous inhabitants and the explorers. In this vital reinterpretation of American history, Short describes how previous accounts of the mapping of the new world have largely ignored the fundamental role played by local, indigenous guides. The exchange of information that resulted from this "cartographic encounter" allowed the native Americans to draw upon their wide knowledge of the land in the hope of gaining a better position among the settlers. This account offers a radical new understanding of Western expansion and the mapping of the land and will be essential to scholars in cartography and American history.
This article reviews the current research and applications of various digital soil mapping (DSM) techniques used to map Soil Organic Carbon (SOC) concentration and stocks following a systematic ...mapping approach from 2013 until present (18 February 2019). It is intended that this review of relevant literature will assist prospective researchers by identifying knowledge clusters and gaps in relation to the digital mapping of SOC. Of 120 studies, most were clustered in some specific countries such as China, Australia and the USA. The highest number publications were in 2016 and 2017. Regarding the predictive models, there was a progression from Linear Models towards Machine Learning (ML) techniques, and hybrid models in Regression Kriging (RK) framework performed better than individual models. Multiple Linear Regression (MLR) was the most frequently used method for predicting SOC, although it was outperformed by other ML techniques in most studies. Random Forest (RF) was found to perform better than MLR and other ML techniques in most comparative studies. Other common and competitive techniques were Cubist, Neural Network (NN), Boosted Regression Tree (BRT), Support Vector Machine (SVM) and Geographically Weighted Regression (GWR). Due to the inconsistency in various comparative studies, it would be advisable to calibrate the competitive algorithms using specific experimental datasets. This review also reveals the environmental covariates that have been identified as the most important by RF technique in recent years in regard to digital mapping of SOC, which may assist in selecting optimum sets of environmental covariates for mapping SOC. Covariates representing organism/organic activities were among the most frequent among top five covariates, followed by the variables representing climate and topography. Climate was reported to be influential in determining the variation in SOC level at regional scales, followed by parent materials, topography and land use. However, for mapping at a resolution that represents smaller areas such as a farm- or plot-scale, land use and vegetation indices were stated to be more influential in predicting SOC. Furthermore, unlike a previous review work, all recent studies in this review incorporated validation and 41% of them estimated spatially explicit prediction of uncertainty. Only 9.16% studies performed external validation, whereas most studies used data-splitting and cross-validation techniques which may not be the best options for datasets obtained through non-probability sampling.

Abstract Maps play a central role in the transfer of knowledge for biodiversity conservation. However, their production and reception contexts have not been sufficiently investigated so far. While ...critical cartography has demonstrated that maps are not objective representations of nature but are influenced by social conventions, these insights have not been fully reflected in ecological mapping practice. This paper draws on critical map theory and expands it with a critical evaluation of map visualization. By analyzing the design of biodiversity maps, our study demonstrates that the way biodiversity is visualized in maps does not adequately reflect the dynamics and interdependencies of natural systems, nor does it adequately reflect the species-specific needs. It is argued that design-led research provides relevant knowledge about evaluating maps in terms of their functionality as communication tools. This is of central importance if we wish to further develop ecological cartography and make it practicable and effective in its field of application.
