Abstract:
This article examines the maps of Minsk of the late XVIII – early XIX century as the sources on social topography of the city. Socio-topographic approach in history implies combining topographic data and social research. City maps have been traditionally viewed as the sources for reconstructing urban topography. However, they often contain valuable data on population of the city, thus it is suggested viewing the maps of Minsk as the carriers of two types of information – topographic and social. Having prepared a review of twenty city maps, the author demonstrates the context of their emergence and provides brief description. The importance of city maps for reconstruction of its topography is underlined. Bases on studying the cartographic content of maps, the author reproduces the image of Minsk of the late XVIII – early XIX; determines the records on social characteristics of urban population. The meaning of cartographic sources for examination of social topography of Minsk is defined.

Abstract:
Topographic maps provide both a detailed and accurate representation of cultural and natural features on the ground and a quantitative representation of relief, usually using contour lines. They can be used to address spatial questions in disciplines related to natural resources, hydrology, forestry, agriculture, or ecology. In 1879, the United States Geological Survey began to map the topography of the United States, producing new map versions of each area at semi-regular time intervals. US Topo maps are the current generation of USGS topographic maps. Unlike traditional topographic maps, the US Topo product is automatically generated from national map databases with topographic maps and produced every three years for all 48 of the contiguous United States, Hawaii, and the United States territories. They are published as freely available geospatial PDF documents that facilitate coordinate readings and spatial measurements (e.g. distance, area) through built-in georeferencing technology. This 7-page fact sheet written by Hartwig H. Hochmair and Adam R. Benjamin and published by the UF/IFAS School of Forest Resources and Conservation focuses on US Topo quadrangle download procedures and layer structure. https://edis.ifas.ufl.edu/fr432

Abstract:
From the beginning of the twentieth century, topographic maps for the Libyan state carried out by various compilers, where the first mapping was carried out by the Italian Military Geographical Institute, the Soviet Union Military, and the U.S. Army, followed by mapping carried out by the Libyan state from the 1950s to the 2000s. Most of these maps have not been digitized and updated using the techniques of geographic information systems and remote sensing. This paper discusses on the objectives, methodology and results of the Libya Topography Project, “Libya Topo” for updating the previously compiled topographical map at scale, 1:250000. Open spatial data from different platforms (OSM, Logistics Cluster, Landsat 8 satellite imagery, and SRTM data, etc.). Also, POIs extracted from previously compiled topographic and geological maps. Spatial database for each UTM zone created to store the features and raster. As for the cartographic style, the map layout adopted is the style of the U.S. Defense Mapping Agency maps. The results of the project are an update of 121 topographical map sheets using Quantum (GIS), those will be freely available for the interested users on request (e.g., environmentalists, academics, and university students, etc.).

Abstract The objective of research concerned verifying the accuracy of the location and shape of selected lakes presented on topographical maps from various periods, drawn up on different scales. The area of research covered lakes situated in North-Western Poland on the Międzychód-Sieraków Lakeland. An analysis was performed of vector maps available in both analogue and digital format. The scales of these studies range from 1:50 000 to 1:10 000. The source materials were current for the years 1907 through 2013. The shape and location of lakes have been verified directly by means of field measurements performed using the GPS technology with an accuracy class of RTK. An analysis was performed of the location and shape of five lakes. The analysed water regions were vectorised, and their vector images were used to determine quantitative features: the area and length of the shoreline. Information concerning the analysed lakes obtained from the maps was verified on the basis of direct field measurements performed using a GPS RTK receiver. Use was made of georeferential corrections provided by the NAVGEO service or a virtual reference station generated by the ASG EUPOS system. A compilation of cartographic and field data formed the basis for a comparison of the actual area and the length of the shoreline of the studied lakes. Cartographic analyses made it possible to single out the most reliable cartographic sources, which could be used for the purposes of hydrographical analyses. The course of shorelines shows the attached map.

Abstract:
Recently there has been an outburst of interest in extending topographic maps of vectorial data to more general data structures, such as sequences or trees. However, there is no general consensus as to how best to process sequences using topographic maps, and this topic remains an active focus of neurocomputational research. The representational capabilities and internal representations of the models are not well understood. Here, we rigorously analyze a generalization of the self-organizing map (SOM) for processing sequential data, recursive SOM(RecSOM) (Voegtlin, 2002), as a nonautonomous dynamical system consisting of a set of fixed input maps. We argue that contractive fixed-input maps are likely to produce Markovian organizations of receptive fields on the RecSOM map. We derive bounds on parameter β (weighting the importance of importing past information when processing sequences) under which contractiveness of the fixed-input maps is guaranteed. Some generalizations of SOM contain a dynamic module responsible for processing temporal contexts as an integral part of the model. We show that Markovian topographic maps of sequential data can be produced using a simple fixed (nonadaptable) dynamic module externally feeding a standard topographic model designed to process static vectorial data of fixed dimensionality (e.g., SOM). However, by allowing trainable feedback connections, one can obtain Markovian maps with superior memory depth and topography preservation. We elaborate on the importance of non-Markovian organizations in topographic maps of sequential data.

Abstract:
The main objective of this study is to describe the preparation of topographic maps using the Surfer software. A total of 159 regularly distributed Ground Control Points (GCPs) were collected with the use of the Differential Global Positioning System (DGPS). Seven methods (Contour Map, Post Map, 3D Surface Map, 3D Wireframe Maps, Grid Vector-1 Map, Color Relief Map, and Shaded Relief Maps) at the Surfer environment were used to prepare the topographic maps at the Mukhtar Village near the Al-Fallujah City. Contour lines with other features were superimposed on the DEM layer, which refers to the topography of the terrain inside this study area. The accuracy of the database's results was estimated, essential maps were given, and the results were efficient and effective. The most appropriate method to represent topographic maps was proposed, each of these techniques has been enough to provide us with a general understanding of the subject area.

Abstract:
This work develops and tests the hypothesis that similarity of meaning derives from substitution regularities in the linguistic environment, represented topographically in the brain. We develop a general mathematical theory of semantic space models and use this to motivate a set of new methods for high-dimensional space construction. We then develop a low-dimensional topographic map model of the lexicon from statistical considerations and apply both models to a range of semantic priming experiments. We show that both models capture a large number of previously un-modelled semantic relations. We model association! semantic relatedness and their interaction, and offer a new theory of associative priming. We then demonstrate that, contrary to previous findings, the models also replicate graded and mediated priming effects. Mediated priming is of theoretical importance to memory models because its existence has been taken as evidence for spreading activation and against compound cue models. We show how a semantic space account representing only substitutability relations can account for mediated priming without making any specific architectural assumptions.

Full text
Abstract:
The thesis builds upon the hypothesis that the spatial arrangement of topographic features, such as buildings, roads and other land cover parcels, indicates how land is used. The aim is to make this kind of high-level semantic information explicit within topographic data. There is an increasing need to share and use data for a wider range of purposes, and to make data more definitive, intelligent and accessible. Unfortunately, we still encounter a gap between low-level data representations and high-level concepts that typify human qualitative spatial reasoning. The thesis adopts an ontological approach to bridge this gap and to derive functional information by using standard reasoning mechanisms offered by logic-based knowledge representation formalisms. It formulates a framework for the processes involved in interpreting land use information from topographic maps. Land use is a high-level abstract concept, but it is also an observable fact intimately tied to geography. By decomposing this relationship, the thesis correlates a one-to-one mapping between high-level conceptualisations established from human knowledge and real world entities represented in the data. Based on a middle-out approach, it develops a conceptual model that incrementally links different levels of detail, and thereby derives coarser, more meaningful descriptions from more detailed ones. The thesis verifies its proposed ideas by implementing an ontology describing the land use ‘residential area’ in the ontology editor Protégé. By asserting knowledge about high-level concepts such as types of dwellings, urban blocks and residential districts as well as individuals that link directly to topographic features stored in the database, the reasoner successfully infers instances of the defined classes. Despite current technological limitations, ontologies are a promising way forward in the manner we handle and integrate geographic data, especially with respect to how humans conceptualise geographic space.

Abstract:
A geographic information system (GIS) was used to create landform measurements and maps for elevation, slope, aspect, landform index, relative phenologic change, and slope position for 3 topographic quadrangles in Virginia. A set of known observation points of the Northern dusky flying squirrel (Glaucomys sabrinus) was used to build 3 models to delineate sites with landform characteristics equivalent to those known points. All models were built using squirrel observation points from 2 topographic quadrangles. The first model, called "exclusionary", excluded those pixels with landform characteristics different from the known squirrel pixels based on histogram analyses. Logistic regression was used to create the other 2 models. Each model resulted in an image of pixels considered equivalent to the known squirrel pixels. Each model excluded approximately 65% of the Highland study area, but the exclusionary model excluded the fewest known squirrel pixels (12.62%). Both logistic regression models excluded approximately 10% more known squirrel pixels than the exclusionary approach. The models were tested in the area of a third quadrangle with points known to be occupied by squirrels. After the model was applied to the third topographic quadrangle, the exclusionary model excluded the least amount of full-area pixels (79.30%) and only 14.81% of the known squirrel pixels. The second logistic regression excluded 81.16 % of the full area and no known squirrel pixels. All models proved useful in quickly delineating pixels equivalent to areas where wildlife were known to occur.

Abstract:
This study aims to refine the current cartographic standards and specifications used by the Australian Defence Force to produce the 1:50 000 scale Topographic Line Map (TLM) so that TLMs can be read with both normal chromatic vision and with achromatic NVG vision. The proliferation and integration of Night Vision Goggles (NVG) into the Australian Army has increased the operating capacity of forces at night. The Australian Army has incorporated NVG into standard operating procedures and training to the effect that Australian military personnel do not operate, at night, without NVG. The increased use of NVG in the Australian Army has required existing systems to be modified or redesigned to be effective within the limitations of NVG. The inability to read TLMs effectively with NVG is an identified problem within the Australian Army. This research has investigated the problems associated with using NVG and the information, which cannot be read on TLMs with NVG. This information was compared to a survey of features on a TLM that are critical for successful military operations. The combined information determined which features on a TLM were to be refined to enable effective reading with NVG. The scope of this research limited refinements to current or previous cartographic standards and specifications used by the Australian Army to produce TLMs. Refinements were limited to symbology, size, and colour and three critical information features of contours, watercourses and vegetation. The problems of cartographic design for a dual vision system (chromatic/achromatic) were investigated and it was determined that the common factor of value contrast exhibits the greatest effect on the refinement process. Prototype TLMs were produced and tested with normal and NVG vision to determine the best cartographic portrayal of the critical information features, without compromising the Figure/ground relationship, balance and cognitive meanings of the TLM. A final product was produced from the prototype experiment results providing a TLM for use with both normal and NVG vision. The refined TLM has changed contours from brown to black without changes to symbology or size and watercourses from 0.1mm width to 0.2mm width without changing colour or symbology. Vegetation was retained at the current standard and specification.

Abstract:
Historic maps are an important primary source which can be utilized in the reconstruction of environmental variables of the pre-industrial landscape. However, methodological constraints have hitherto prevented large scale and systematic approaches. In this paper a novel methodology is presented, which documents the usefulness of the maps in the study of paleo-hydrology and thus serves a better understanding of the conditions for agricultural production under pre-drainage conditions. The methodology is developed based on eighteenth and nineteenth century maps from a 100 km2 study area in one stream catchment in East Jutland, Denmark. It combines information from two types of historic maps in order to correlate computed soil hydrology (wetness index) and recorded historic land-use. The calculated wetness indexes are derived from contour lines on topographic (military) maps (in Danish: Høje Maalebordsblade), whereas the spatial overlays are land-use classes from economic maps (in Danish: Matrikelkort - Original 1). This study demonstrates – for the first time - that the wetness index is explanatory for the agricultural suitable/non-suitable dichotomy (tilled land versus “wetland”: meadows, fens, and peat bogs) on the historic economic maps. Furthermore, the study shows that pre-industrial arable areas were stretched to their limits in respect to cropping wet soils in this agricultural dominated landscape. The study confirms the existing belief that the historic economic maps constitute the best available source of these mosaic-landscapes for periods before the intense subsurface tile drainage began. This finding opens for further methodological development and up-scaling using automatic feature detection, contour line extraction and text recognition of historical maps.

Abstract:
The research provides assessment of current and longer-term consequences of iron ore open pit mining for land resources of adjacent areas. There are applied methods of analysis of fund materials; comparison of topographic sheets and special maps, visual observation, soil testing, laboratory analyses and statistic processing of data obtained. It is revealed that facilities of iron ore mining and concentration waste accumulation (dumps and tailing ponds) are destructive factors for the local lithosphere, dust chemical contamination being the basic one. The steps aimed at reducing negative impacts of technogenic objects of the mining and raw material complex on the environment are under study.

Abstract:
This paper presents a new data fusion multiscale observation product (MOP) for flood emergencies. The MOP was created by integrating multiple sources of contributed open-source data with traditional spaceborne remote sensing imagery to provide a sequence of high spatial and temporal resolution flood inundation maps. The study focuses on the 2015 Memorial Day floods that caused up to US$61 million of damage. The Hydraulic Engineering Center River Analysis System (HEC-RAS) model was used to simulate water surfaces for the northern part of the Trinity River in Dallas, using reservoir surcharge releases and topographic data provided by the US Army Corps of Engineers. A measure of fit assessment is performed on the MOP flood maps with the HEC-RAS simulated flood inundation output to quantify spatial differences. Estimating possible flood inundation using individual datasets that vary spatially and temporally allow an understanding of how much each observational dataset contributes to the overall water estimation. Results show that water surfaces estimated by MOP are comparable with the simulated output for the duration of the flood event. Additionally, contributed data, such as Civil Air Patrol, although they may be geographically sparse, become an important data source when fused with other observation data.
