“…LiDAR data are also increasingly being used for mapping volcanoes and their eruptive products (e.g., Cashman et al, ) by characterizing the intensity of laser returns from lava flows (Mazzarini et al, ) or deriving highly accurate digital terrain models (DTMs) of active flows (Favalli et al, ) and deposits (e.g., Csatho et al, ; Scott et al, ). LiDAR observations have also been used to map surface roughness and differentiate lava flow terrains (Morris et al, ; Whelley et al, ; Whelley, Garry, et al, ; Whelley, Scheidt, et al, ). Terrestrial Laser Scanning (TLS) is a type of LiDAR scanning, used at each RIS 4 E EVA location that uses a tripod‐mounted instrument (Figure ).…”

Field portable instrumentation, such as in situ geochemical analyzers or broader field of view instruments like multispectral imagers or other imaging capabilities, has the potential to dramatically increase the science return of a planetary surface exploration mission. However, more work is needed to determine how emerging portable technologies should be designed and implemented into evolving mission architectures. This work summarizes the efforts of the RIS4E (Remote, In Situ and Synchrotron Studies for Science and Exploration) SSERVI (Solar System Exploration Research Virtual Institute) team in investigating how field portable instruments should be including into planning for future exploration EVAs (extravehicular activities). EVA crews of geologists and astronauts tested a variety of portable and handheld technologies at both the December 1974 lava flow, Kilauea Volcano, Hawai'i, and Kilbourne Hole, New Mexico, both of which are planetary analog sites. The timeline data gathered during instrument deployment were then mapped onto EVA timelines used in large‐scale NASA planetary surface exploration analog missions. Results and recommendations for future instrument hardware and software development are discussed, as is the operational framework necessary for incorporating in situ analytical capabilities into future planetary surface exploration.

“…A lower value means low separability and higher value shows higher spectral separability between ecotope pair. A higher value of JM distance is desirable for better identification of classes (Whelley et al, 2014).…”

“…There are many state of the art segmentation and classification algorithms available. It is necessary to make full use of the advantages of different algorithms on the basis of multi-feature fusion, so as to achieve better segmentation effect (Yuheng and Hao, 2017). Hence, in this study a combination of segmentation algorithms is deployed.…”

Monitoring environmental supporting conditions of a raised bog using remote sensing techniques

Abstract. Conventional methods of monitoring wetlands and detecting changes over time can be time-consuming and costly. Inaccessibility and remoteness of many wetlands is also a limiting factor. Hence, there is a growing recognition of remote sensing techniques as a viable and cost-effective alternative to field-based ecosystem monitoring. Wetlands encompass a diverse array of habitats, for example, fens, bogs, marshes, and swamps. In this study, we concentrate on a natural wetland – Clara Bog, Co. Offaly, a raised bog situated in the Irish midlands. The aim of the study is to identify and monitor the environmental conditions of the bog using remote sensing techniques. Environmental conditions in this study refer to the vegetation composition of the bog and whether it is in an intact (peat-forming) or degraded state. It can be described using vegetation, the presence of water (soil moisture) and topography. Vegetation indices (VIs) derived from satellite data have been widely used to assess variations in properties of vegetation. This study uses mid-resolution data from Sentinel-2 MSI, Landsat 8 OLI for VI analysis. An initial study to delineate the boundary of the bog using the combination of edge detection and segmentation techniques namely, entropy filtering, canny edge detection, and graph-cut segmentation is performed. Once the bog boundary is defined, spectra of the delineated area are studied. VIs like NDVI, ARVI, SAVI, NDWI, derived using Sentinel-2 MSI and Landsat 8 OLI are analysed. A digital elevation model (DEM) was also used for better classification. All of these characteristics (features) serve as a basis for classifying the bog into broad vegetation communities (termed ecotopes) that indicate the quality of raised bog habitat. This analysis is validated using field derived ecotopes. The results show that, by using spectral information and vegetation index clustering, an additional linkage can be established between spectral RS signatures and wetland ecotopes. Hence, the benefit of the study is in understanding ecosystem (bog) environmental conditions and in defining appropriate metrics by which changes in the conditions can be monitored.

“…They can be classified into first returns, reflected from the tree tops, intermediate returns, from the leaves or branches, and last returns, reflected from the ground. Aerial laser scanning has many uses: measuring agricultural productivity (Saeys et al 2009), distinguishing faint archaeological evidences (Bennett 2012), forestry practices (Hyyppä et al 2012), advancing the science of geomorphology (Sofia et al 2014), measuring volcano uplift (Whelley et al 2014), glacier decline and snowpack (Abermann et al 2010), and providing data for topographic mapping, to name just a few. Using the LiDAR point cloud data, one can extract specific features, such as dimensions of underground ancient structures or aboveground parameters of individual trees (Popescu et al 2003, Popescu 2007, Edson & Wing 2011, Dalponte et al 2014, and obtain ecosystem level information such as forests biomass or carbon sequestration capacity (Lefsky et al 2005, Popescu 2007, García et al 2010, Lee et al 2013.…”

An integrated airborne laser scanning approach to forest management and cultural heritage issues: a case study at Porolissum, Romania

Abstract. This paper explores the opportunities that arise where forest ecosystem management and cultural heritage monuments protection converge. The case study area for our analysis was the landscape surrounding the Moigrad-Porolissum Archaeological site. We emphasize that an Airborne Laser Scanning (ALS or LiDAR-Light Detection and Ranging) approach to both forest management and cultural heritage conservation is an outstanding tool, assisting policy-makers and conservationists in decision making for integrated planning and management of the environment. LiDAR-derived surface models enabled a synoptic, never-seen-before view of the ancient Roman frontiers defensive systems while also revealing the present forest road network. The thorough and accurate road inventory data are very useful for updating and modifying forest base maps and registries and also for identifying the priority sectors for archaeological discharge. The ability to identify and determine optimal routes for forest management and to locate previously unmapped ancient archaeological remains aids in reducing costs and creating operational efficiencies as well as in complying with the legislation and avoiding infringements. The potential of LiDAR to demonstrate the long-term and comprehensive human impact on wooded areas is discussed. We identified a significant historical landscape change, consisting of a deforestation period, spanning over more than 160 years, during the Roman Period in Dacia (106-271 AD). The transdisciplinary analysis of the LiDAR data provides the base for combining knowledge from archaeology, forestry and environmental history in order to achieve a thorough analysis of the landscape changes and history. In the "nature versus culture" dichotomy, the landscape, outfield areas and forests are primarily perceived as nature, while in reality they are often heavily marked by human impact. LiDAR offers an efficient method for broadening our knowledge regarding the character and extent of human interaction with landscapes -forested or otherwise.
