Abstract:

<p><strong>Abstract.</strong> The map which shows the large-scale topography on the earth is made variously even now. We made a Topographic map as IN-YOU-ZU from topographic data, too. An ambiguous part became easy to judge by a result and conventional expression method. A study of the map world is developed by using IN-YOU-ZU as a background map, and We will think with explication of the topography structure and expect scientific progress. A made Topographic map is using exhibited topographic public data. When more in-depth data can be used, it's expected that the precision of the expressive power rises more. Geographical Survey Institute make the basic mapinformation 5&thinsp;m mesh DEM, 500&thinsp;m mesh water depth data (J-EGG500) by JODC and the data of TOPO1 of World are used for a Topographic map.</p><p>Theoretically, it's the Topographic map by which the modelling is put the accent on to add the temperature(cold or warm) color of the difference between the inside of the geomorphic surface mean and the plane where the outside is made the wavelength as the depth (or the height). The one to which the name of the large-scale tectonic forms was attached about the world topographical map is Figure 1. The world topographical map by IN-YOU-ZU.</p>

Abstract:

Based on the Guobu topographic survey project in Laxiwa hydropower station at Yellow River, different models of Riegl laser scanning equipment were used to measure each testing area’s topography. Laser scanning measuring technique plays a great role in the process of the hydroelectric topographic survey, and its efficiency works several times higher than that of using traditional measuring means. Moreover, it also can shorten measurement period and reduce the field cost of production, which can achieve good economic benefits and social benefits consequently.

Abstract:

The combination of Global Positioning System-Real Time Kinematic (GPS-RTK) and depth sounder is an important technical method of modern underwater topographic survey. In this paper, the combined technology was integrated with unmanned surface vehicle (USV) technology to construct an unmanned survey system suitable for underwater topographic survey in stilling basin, and it was applied to survey the underwater topography of the stilling basin of Tingzikou hydrojunction project. Based on the surveying and mapping data and 3D model, the trend of elevation change of the stilling basin including apron, end sill, antiscour section, and river convergence section was analyzed. The results show that, for the surface outlet stilling basin of Tingzikou, after flood, the structure is complete, the boundaries are clear, the water quality is good, and there is little sediment on the surface of apron from overflow dam section to end sill. Furthermore, no obvious sediment or structural abnormality has been found in the still basin. Affected by the bedrock and cofferdam cobble gravel sediment, the elevation of the antiscour section and the downstream convergence section of the surface outlet stilling basin increased significantly. For the bottom outlet stilling basin of Tingzikou, there is large sediment within a range of 20 m∼40 m from the bottom sill and the maximum height of it reaches 2.04 m, while there is no obvious sediment or structural abnormality in the remaining region of basin. The critical sedimentation height can effectively judge the safety grade of the sedimentation height in stilling basin and provide a reliable support for assessing the overall safety of stilling basin. The application of unmanned survey technology improves the accuracy and timeliness of underwater topography and sedimentation distribution of stilling basin, which has significant application research value and promotion significance.

Abstract:

Abstract. The U.S Geological Survey is exploring the use of machine learning and geospatial artificial intelligence (GeoAI) for topographic mapping tasks. These automated tasks include extracting topographic features such as hydrography, transportation, vegetation canopy, urban 3D structures, and others from raw data including lidar point clouds, color and near infrared images, historic topographic maps, and Web sources of existing geospatial resources. Current (2020) work includes extracting hydrography from elevation data, and geomorphic features with geographic names from historical topographical maps using Deep Learning. Extracted features are included in a geographic information system (GIS), supporting topographic mapping and modeling activities, and as semantic entities in a graph data model, building a knowledge graph for topographic data. These GIS datasets and topographic knowledge graphs can be used in automated topographic mapping processes and artificial intelligence routines that develop data for hydrologic, biologic, and geologic models that form part of the USGS EarthMap vision.

Extracting topographic characteristics of landforms typical of Canadian agricultural landscapes for agri-environmental modeling. I. Methodology. Can. J. Soil Sci. 91: 251–266. Soil and topographic information are key inputs for many agri-environmental models and there are linkages between soil and topography at the field scale. A major source of soil data is soil databases established based on field soil survey. Although both soil and topographic information are recorded in field soil surveys, the nominal nature of the topographic data has limited their use in agri-environmental models. In this study, we developed a methodology to extract various topographic derivatives and to classify the landscape into landform elements with distinctive topographic characteristics based on detailed analyses of fine resolution digital elevation models. Data obtained from these analyses were used to calculate a representative two-dimensional hillslope of five segments, each with a defined length and slope gradient. A set of modal hillslopes was developed to describe topographic variability. Additional topographic parameters, ratios and indices were calculated to reflect different aspects of topographic characteristics and also to build connections between different agri-environmental models. In particular, a topographic complexity index was developed as a quantitative measure of the degrees of divergence and convergence. This paper describes the methodology using one site as an example. Application of this methodology to other landforms in agricultural land of Canada is reported in a companion paper.

Full text

Abstract:

Les dunes côtières constituent un des éléments fondamentaux de la dynamique des systèmes côtiers sableux. Leur stabilité dépend essentiellement de leur capacité à résister aux effets des tempêtes et à se reconstituer après l'érosion. Dans le contexte actuel du changement climatique, la probable hausse du niveau de la mer devrait affecter considérablement les systèmes côtiers et de surcroît augmenter la vulnérabilité des cordons dunaires à l'érosion.L'objectif principal de cette thèse est d'étudier l'évolution des littoraux dunaires de la Côte d'Opale en adoptant une approche à plusieurs échelles de temps afin d'évaluer leur capacité de résistance et/ou de régénération face aux événements tempétueux. A long terme, l'étude de l'évolution du trait de côte sur près de 68 ans, à partir de photographies aériennes orthorectifiées, a révélé que plus de la moitié des littoraux dunaires de la Côte d'Opale sont stables ou en accumulation et possèdent donc une bonne capacité de résilience, malgré les nombreuses tempêtes ayant affecté ce littoral depuis le début des années 50. L'analyse de leur évolution sur un pas de temps de 5 ans a mis en évidence une forte variabilité spatiale et temporelle directement liée aux forçages météo-marins, notamment aux épisodes tempétueux associés à des hauts niveaux d'eaux. A moyen et court termes, des levés topographiques LiDAR et des mesures in-situ, couplés aux données météorologiques et hydrodynamiques, ont révélé une réponse morphologique différente entre des secteurs dunaires adjacents. Celle-ci est liée à la variation des paramètres morphologiques (altitude de pied de dune, largeur et volume du haut de plage) au cours des périodes étudiées. Les résultats montrent également que les processus de régénération peuvent être très longs sur nos sites d'étude, ce qui suggère que les dunes cotières qui, jusqu'à présent étaient relativement stables, risquent de connaître des épisodes d'érosion plus fréquents avec l'élévation contemporaine du niveau de la mer
Coastal dunes are fundamental elements of sandy coastal systems dynamic. They may experience a variable response to coastal erosion, in relation to their ability to withstand storm effects and to recover from erosion. Global sea level rise, related to global warming, would considerably affect coastal systems and hence the sensitivity of coastal dunes to erosion. The main objective of this thesis is to study the evolution of the Côte d'Opale coastal dunes at different time scales in order to evoluate their capacity to resist and/or to recover from storm impacts. Over long term periods (nearly 68 years), shoreline evolution analysis from orthorectified aerial photographs revealed that more than half of the Côte d'Opale coastal dunes are stable or prograding and thus, are resilient. Their evolution over 5-year periods highlighted a strong spatial and temporal variability which is directly linked to weather and hydrodynamic conditions, especially the occurence of storms during heigh water levels. At medium and short term scales, topographic surveys from LiDAR and in-situ measurements, coupled with metrological and hydrodynamic data, showed a different morphological response between adjacent coastal dune areas. This is related to variations in morphological parameters such as dune foot elevation, width and volume of the upper-beach during the studied periods. Results show also that coastal dunes recovery from storms can be a very long process at our study areas, suggesting that foredunes in a state of mesoscale stability may experience more frequent erosion with currents sea level rise

Abstract:

The primary objective of this research was to perform an in vitro assessment of the ability of microscale topography to alter cell behaviour, with specific regard to producing favourable topography in an orthopaedic ceramic material suitable for implantation in the treatment of arthritis. Topography at microscale and nanoscale alters the bioactivity of the material. This has been used in orthopaedics for some time as seen with optimal pore size in uncemented hip and knee implants. This level of topography involves scale in hundreds of micrometres and allows for the ingrowth of tissue. Topography at smaller scale is possible thanks to progressive miniaturisation of technology. A topographic feature was created in a readily available clinically licensed polymer, Polycaprolcatone (PCL). The effect of this topography was assessed in vitro. The same topography was transferred to the latest generation composite orthopaedic ceramic, zirconia toughened alumina (ZTA). The fidelity of reproduction of the topography was examined using scanning electron microscopy (SEM) and atomic force microscopy (AFM). These investigations showed more accurate reproduction of the topography in PCL than ZTA with some material artefacts in the ZTA. Cell culture in vitro was performed on the patterned substrates. The response of osteoprogenitor cells was assessed using immunohistochemistry, real-time polymerase chain reaction and alizarin staining. These results showed a small effect on cell behaviour. Finally metabolic comparison was made of the effects created by the two different materials and the topography in each. The results have shown a reproducible topography in orthopaedic ceramics. This topography has demonstrated a positive osteogenic effect in both polycaprolactone and zirconia toughened alumina across multiple assessment modalities.

Abstract:

Shetland boasts exceptionally well-preserved, but largely overlooked, field systems spanning a period of approximately 4000 years (Neolithic/Bronze Age – Viking/Norse). These have the potential to vastly increase our understanding of past agricultural practices and life styles. This study uses topographical survey, Shape Analysis, GIS, soil survey and micromorphology to answer questions relating to their location, form and function/management, pioneering the use of new tools and testing current models. An holistic landscape approach to the field systems is developed and tested against a multi-period site. Previously unknown types and periods of field systems are identified through survey and shape analysis, tools demonstrated to be valuable in refining the emerging model of field classification. GIS has illuminated pre-, during and post- construction factors influencing boundary form. New insights into location arise from the survey and GIS. Soils work has demonstrated that existing models of soil management over-simplify a complex situation, that thin acidic soils retain cultural information and that accretion was important to the sustainability of these peaty soils. While soils were sustainable over extended periods, the cultural inheritance of managed land appears to be limited. This thesis therefore presents the most holistic and comprehensive understanding of Shetland field systems which has so far been attempted.

Abstract:

The following presents a method for determining topographic elevation error for overland unstructured finite element meshes derived from bare earth LiDAR for use in a shallow water equations model. This thesis investigates the development of an optimal interpolation method to produce minimal error for a given element size. In hydrodynamic studies, it is vital to represent the floodplain as accurately as possible since terrain is a critical factor that influences water flow. An essential step in the development of a coastal inundation model is processing and resampling dense bare earth LiDAR to a DEM and ultimately to the mesh nodes; however, it is crucial that the correct DEM grid size and interpolation method be employed for an accurate representation of the terrain. The following research serves two purposes: 1) to assess the resolution and interpolation scheme of bare earth LiDAR data points in terms of its ability to describe the bare earth topography and its subsequent performance during relevant tide and storm surge simulations.

Abstract:

Since the texture of surfaces plays a key role in the shaping of many environmental processes, high resolution measurements are important to study these phenomena. Specifically, 3-D point cloud data is desirable to document river shape and evolution, surface roughness, and erosion-sedimentation processes. The best method of obtaining these measurements is using a terrestrial laser scanner. However, these are too expensive for limited-use experiments. Therefore, I developed a simple, affordable, and robust system used to acquire high resolution data relating to hydraulic and fluvial environments.

Full text

Abstract:

Within the last decade, airborne lidar (Light Detection And Ranging) equipment has evolved to the point where it can provide accurate ground surface elevations on a dense grid (often 1m by 1m) along pipeline corridors, at a cost that is a fraction of the cost for a comparable ground based topographic survey. This paper explains how lidar is used to acquire topographic data and how the data are converted to digital terrain models referenced to geodetic benchmarks. The accuracy and density of topographic data acquired by lidar surveys can be used to greatly facilitate pipeline design and reduce pipeline construction costs. The major benefits include: 1) The density of ground surface elevations obtained using lidar are significantly better than can be obtained using photogrammetry or conventional ground based survey methods. 2) The survey data can be collected over large areas in a matter of days and with virtually no disturbance to landowners. 3) The digital terrain models derived from lidar survey data can be imported into existing drafting (CAD) software and used to efficiently generate centerline profiles, cross-sections and alignment sheets as required for pipeline design and construction. 4) Hillshade maps derived from lidar data have proven extremely useful in pipeline route studies because they allow surface features to be identified and often avoided, thereby minimizing pipeline construction and operating costs.

Abstract:

A low-cost multicamera Unmanned Aircraft System (UAS) is used to simultaneously estimate open-coast topography and bathymetry from a single longitudinal coastal flight. The UAS combines nadir and oblique imagery to create a wide field of view (FOV), which enables collection of mobile, long dwell timeseries of the littoral zone suitable for structure-from motion (SfM), and wave speed inversion algorithms. Resultant digital surface models (DSMs) compare well with terrestrial topographic lidar and bathymetric survey data at Duck, NC, USA, with root-mean-square error (RMSE)/bias of 0.26/–0.05 and 0.34/–0.05 m, respectively. Bathymetric data from another flight at Virginia Beach, VA, USA, demonstrates successful comparison (RMSE/bias of 0.17/0.06 m) in a secondary environment. UAS-derived engineering data products, total volume profiles and shoreline position, were congruent with those calculated from traditional topo-bathymetric surveys at Duck. Capturing both topography and bathymetry within a single flight, the presented multicamera system is more efficient than data acquisition with a single camera UAS; this advantage grows for longer stretches of coastline (10 km). Efficiency increases further with an on-board Global Navigation Satellite System–Inertial Navigation System (GNSS-INS) to eliminate ground control point (GCP) placement. The Appendix reprocesses the Virginia Beach flight with the GNSS–INS input and no GCPs.

Abstract:

This study was conducted to inventory, classify, and map soils and vegetation within the ecosystems of Katmai National Park and Preserve (KATM) using an ecological land survey (ELS) approach. The ecosystem classes identified in the ELS effort were mapped across the park, using an archive of Geo-graphic Information System (GIS) and Remote Sensing (RS) datasets pertaining to land cover, topography, surficial geology, and glacial history. The description and mapping of the landform-vegetation-soil relationships identified in the ELS work provides tools to support the design and implementation of future field- and RS-based studies, facilitates further analysis and contextualization of existing data, and will help inform natural resource management decisions. We collected information on the geomorphic, topographic, hydrologic, pedologic, and vegetation characteristics of ecosystems using a dataset of 724 field plots, of which 407 were sampled by ABR, Inc.—Environmental Research and Services (ABR) staff in 2016–2017, and 317 were from existing, ancillary datasets. ABR field plots were located along transects that were selected using a gradient-direct sampling scheme (Austin and Heligers 1989) to collect data for the range of ecological conditions present within KATM, and to provide the data needed to interpret ecosystem and soils development. The field plot dataset encompassed all of the major environmental gradients and landscape histories present in KATM. Individual state-factors (e.g., soil pH, slope aspect) and other ecosystem components (e.g., geomorphic unit, vegetation species composition and structure) were measured or categorized using standard classification systems developed for Alaska. We described and analyzed the hierarchical relationships among the ecosystem components to classify 92 Plot Ecotypes (local-scale ecosystems) that best partitioned the variation in soils, vegetation, and disturbance properties observed at the field plots. From the 92 Plot Ecotypes, we developed classifications of Map Ecotypes and Disturbance Landscapes that could be mapped across the park. Additionally, using an existing surficial geology map for KATM, we developed a map of Generalized Soil Texture by aggregating similar surficial geology classes into a reduced set of classes representing the predominant soil textures in each. We then intersected the Ecotype map with the General-ized Soil Texture Map in a GIS and aggregated combinations of Map Ecotypes with similar soils to derive and map Soil Landscapes and Soil Great Groups. The classification of Great Groups captures information on the soil as a whole, as opposed to the subgroup classification which focuses on the properties of specific horizons (Soil Survey Staff 1999). Of the 724 plots included in the Ecotype analysis, sufficient soils data for classifying soil subgroups was available for 467 plots. Soils from 8 orders of soil taxonomy were encountered during the field sampling: Alfisols (<1% of the mapped area), Andisols (3%), Entisols (45%), Gelisols (<1%), Histosols (12%), Inceptisols (22%), Mollisols (<1%), and Spodosols (16%). Within these 8 Soil Orders, field plots corresponded to a total of 74 Soil Subgroups, the most common of which were Typic Cryaquents, Typic Cryorthents, Histic Cryaquepts, Vitrandic Cryorthents, and Typic Cryofluvents.

Abstract:

The main recommendations of the panel report can be summarised under five key headings:  Scotland in the Roman world: Research into Roman Scotland requires an appreciation of the wider frontier and Empire-wide perspectives, and Scottish projects must be integrated into these wider, international debates. The rich data set and chronological control that Scotland has to offer can be used to inform broader understandings of the impact of Rome.  Changing worlds: Roman Scotland’s rich data set should be employed to contribute to wider theoretical perspectives on topics such as identity and ethnicity, and how these changed over time. What was the experience of daily life for the various peoples in Roman Scotland and how did interactions between incomers and local communities develop and change over the period in question, and, indeed, at and after its end?  Frontier Life: Questions still remain regarding the disposition and chronology of forts and forces, as well as the logistics of sustaining and supplying an army of conquest and occupation. Sites must be viewed as part of a wider, interlocking set of landscapes, and the study of movement over land and by sea incorporated within this. The Antonine Wall provides a continuing focus of research which would benefit from more comparison with frontier structures and regimes in other areas.  Multiple landscapes: Roman sites need to be seen in a broader landscape context, ‘looking beyond the fort’ and explored as nested and interlocking landscapes. This will allow exploration of frontier life and the changing worlds of the Roman period. To do justice to this resource requires two elements: o Development-control archaeology should look as standard at the hinterland of forts (up to c.1 km from the ‘core’), as sensitive areas and worthy of evaluation; examples such as Inveresk show the density of activity around such nodes. The interiors of camps should be extensively excavated as standard. o Integrated approaches to military landscapes are required, bringing in where appropriate topographical and aerial survey, LIDAR, geophysics, the use of stray and metal-detected finds, as well as fieldwalking and ultimately, excavation.  The Legacy of Rome: How did the longer term influence of the Romans, and their legacy, influence the formation, nature and organisation of the Pictish and other emergent kingdoms?

Abstract:

The Coastal Observation and Analysis Branch (COAB) located at the Field Research Facility (FRF) conducts quarterly surveys and post-storm surveys along up to 60 kilometers of coastline within the vicinity of the FRF to assess, evaluate, and provide updated observations of the morphology of the foreshore and dune system. The surveys are conducted using a mobile terrestrial LiDAR scanner coupled with an Inertial Navigation System (INS). Traditionally the surveys coincide with a low tide, exposing the widest swath of visible sediment to the scanner as well as enough wind-sea swell or texture to induce wave breaking upon the interior sandbars. The wave field is measured with X-Band radar which records a spatial time series of wave direction and speed. Data for the survey region was collected using the VZ-2000's mobile, 3D scanning mode where the scanner continuously rotates the line scan 360 degrees as the vehicle progresses forward. Elevation measurements are acquired on all sides of the vehicle except for the topography directly underneath the vehicle. As the vehicle moves forward, the next rotation will capture the previous position's occluded data area. Laser data is acquired in mobile 3D radar mode with a pulse repetition rate of 300kHz, theta resolution of 0.19 degrees and phi resolution of 0.625 degrees. Horizontal Datum NAD83(2011), Projection North Carolina State Plane (3200) meters; Vertical Datum NAVD88, meters with geoid09 applied.
