This chapter deals with types, purposes, contents and perspectives of geomorphological mapping, from the widely applied, ‘traditional’ symbol-based maps to the modern geographical information system (GIS)-based, object-oriented geomorphological mapping models, capable of providing reliable multiscale cartographic support to environmental analysis and land planning projects. In the last decades, the availability of new tools such as satellite imagery, global positioning systems, digital elevation models and GIS has induced a new, more effective approach in the acquisition, storage and display of geomorphological features. By this approach, geomorphologists can produce geomorphological models, consisting of land surface ‘objects’, organised into hierarchically arranged classes with spatially and temporally variable properties and geometric relationships. Unlike ‘traditional’ maps, object-oriented models can provide a full geometric description of landforms and near-surface deposits. Moreover, generalisation/decomposition procedures allow the translation of geomorphological objects from larger to smaller scales and vice versa. A case study of a GIS-based, object-oriented geomorphological model, in which ‘traditional’ symbol-oriented mapping is associated with grid-based/object-based analysis, is provided by the Salerno University (Italy) GeoMorphological Information System (GmIS). Some significant examples of traditional geomorphological maps and multiscale object-oriented mapping models produced at the Salerno University are presented in the annexes.read more

Classification and mapping of the ecoregions of Italy
TL;DR: In this article, the authors define the ecoregions of Italy, southern Europe, based on a robust methodological process for classification and mapping and constitute the first comprehensive ecological classification of the country that integrates accurate and updated cartographies and knowledges on climate, vegetation, land units and biogeography.
Journal ArticleDOI
Combining geomorphometry, feature extraction techniques and Earth-surface processes research: The way forward
TL;DR: In this article, a review of the existing literature of geomorphometry and feature extraction can be found, along with some emerging fields of future research in the digital realm, supporting the likely effectiveness of geomorphic and feature extractions as they are advancing the theoretical, empirical and applied dimension of Geomorphology.

Geomorphological hazards susceptibility in high-density urban areas: A case study of Mexico City
TL;DR: In this article, the authors used various geomorphic analyses to develop a feasible methodology to reduce the disaster risk in Iztapalapa district, where they defined three geomorphological regions: the lacustrine plain, the volcanic piedmont and the mountain area.

Improving regional flood risk assessment using flood frequency and dendrogeomorphic analyses in mountain catchments impacted by tropical cyclones
Adolfo Quesada-Román,Adolfo Quesada-Román,Adolfo Quesada-Román,Juan Antonio Ballesteros-Cánovas,Sebastián Granados-Bolaños,Christian Birkel,Markus Stoffel +6 more
TL;DR: In this article, the authors developed regional flood-frequency analyses combining tree-ring based estimation and measurement of peak discharge at monitoring stations during tropical cyclones to derive flood quartiles, which were combined with the Topographic Wetness Index (TWI) to determine regional flood hazards along floodplains.
Journal ArticleDOI
Low-cost UAV applications in dynamic tropical volcanic landforms
TL;DR: In this article, the authors present and promote innovative low-cost low-power UAV surveying for volcanic geomorphology and volcanic hazards in the tropics with heavy rainfall, deep volcanic soils and high relief.

Introduction to remote sensing
TL;DR: The history and scope of remote sensing is described in detail in this paper, where the authors present a detailed overview of the field of Remote Sensing and its application in agriculture, land use and land cover.
Book
Geographic Information Systems and Science
TL;DR: The Third Edition of this bestselling textbook has been fully revised and updated to include the latest developments in the field and still retains its accessible format to appeal to a broad range of students.
Book
Problems of relative growth
TL;DR: This detailed study of the different rates of growth of parts of the body relative to the body as a whole represents Sir Julian Huxley's great contribution to analytical morphology, and it is still a basis for modern investigations in morphometrics and evolutionary biology.
Book
The Ghost in the Machine
TL;DR: Koestler examines the notion that the parts of the human brain-structure which account for reason and emotion are not fully coordinated as discussed by the authors, which may explain the paranoia, violence, and insanity that are central parts of human history.
Book
A hierarchical concept of ecosystems
TL;DR: A more general line of thought based on hierarchy theory has been proposed in this paper, which suggests an objective way of decomposing ecosystems into their component parts and offers a rewarding method for integrating various schools of ecology.
