The Concept of a Georeferential Spatial Database of Topographic–Historical Objects (GSDoT-HO): A Case Study of the Cadastral Map of Toruń (Poland)

In this study, we aimed to further the international discussion on the methodology of applying GIS technology to the editing of large-scale cadastral maps, taking the experience of editing the cadastral map of Toruń from 1910–1915 as an example. We present the concept of building a georeferential spatial database of topographic–historical objects (GSDoT-HO), which includes the stages involved in creating the database, its exemplary structure, and a proposal of good practices in this process, which were developed in the course of previous projects using a geographic information system for Historical Atlases of Polish Towns. Our works included the scanning, calibration, and rectification of a total of 178 sheets of cadastral maps (including 154 sheets of the map of Toruń and 24 sheets of the cadastral map of the then-village of Mokre) at differentiated scales of 1:250, 1:500, 1:1000, and 1:2000. Finally, in the process of vectorization, vector and attribute data were acquired, which made up the final result in the form of GSDoT-HOs. This database was created out of seven information layers with linear or polygon geometries, including the two most important layers, i.e., plots and buildings, which for the then-area of the city of Toruń, contained approximately 5800 and 10,800 vectorised polygon objects, respectively. This article shifts the focus of the discussion of standards in the use of GIS technology to edit Historic Towns Atlases from the development of interactive maps to the construction of a database that should enable comparative studies of urban spaces.

Sediments and bedforms of the Harle tidal inlet (Wadden Sea, Germany)

ABSTRACT The paper presents a map of sediment surface distribution and bedforms in the Harle tidal inlet, German Wadden Sea. Data collection, processing, and map editing were realized within the sublittoral mapping program of Lower Saxony national waters carried out by the NLWKN – Coastal Research Station. The map is the result of the combined use of multibeam echosounder, sub-bottom profiler, and ground-truth data. The sediment characterization is achieved by an unsupervised approach using an Object-Based Image Analysis (OBIA) on a normalized backscatter mosaic, verified by nineteen sediment samples. Morphometrical parameters and sub-bottom data provided important information to identify hard substrates and bedforms.

『대동여지도』 모사본의 형태와 유형 연구

This paper aims to research on the 18 map-copies which are the transcript-edition of Daedongyeojido (大東輿地圖, 1861). In the relationship with the woodblock print, there are cases which are simply copied. In other cases, errors on maps were corrected. And in some cases the map folder system was changed, and the toponyms with the geographical notes were added. Based on the form and contents, the maps were classified into four types. Among them, a group of modified copy edition in which four maps were included has common characteristics in terms of form and contents. The size and geographical contents of those maps show that this transformation was modeled after a woodblock edition in the National Diet Library, Japan. Even though many of the geographical names and notes were originated from the previous manuscript editions of large-scale Joseon maps, newly added notes contain the historical geography of Joseon. The fact that those manuscript copies were made in the 19th century shows that there was a continuous demand for Daedongyeojido. And the addition of contents in maps is for the overcome of the limitations of woodblock maps.

QDM[formula omitted]: A MATLAB toolbox for analyzing quantum diamond microscope (QDM) magnetic field maps

Paleomagnetic measurements of rock magnetizations are typically performed using classical net moment rock magnetometers on bulk, millimeter- to centimeter-sized samples. In this case, the limited spatial resolution effectively averages across the signal of multiple populations of magnetic grains, each of which may have a distinct geological history. Magnetic field imaging with the quantum diamond microscope (QDM) allows for the measurement of weakly magnetic (10−16 Am2) samples at micrometer spatial resolution, potentially isolating the signal of magnetic grain populations and resolving ambiguities from bulk sample analyses. To achieve such high resolution, the QDM retrieves the energy spectrum of nitrogen–vacancy (NV) color centers within micrometer-scale pixels across a millimeter-scale field of view. Therefore, large amounts of data need to be processed to generate a magnetic field map, which itself often requires further specialized analysis. Until now, no freely-available, comprehensive, open-source software package existed that was able to process this type of data. Here we give an overview of the most important features of QDMlab, our open-source MATLAB toolbox for generating and analyzing QDM magnetic field maps of geologic samples. QDMlab utilizes modern computational techniques like graphics processing unit (GPU) and spectral fitting routines as well as automated image alignment algorithms. QDMlab contains easy-to-use functions for (1) generating magnetic field maps from raw QDM data, (2) map editing, and (3) quantifying the net magnetic moment and rock magnetic properties of rock and mineral samples.

Multipurpose GIS Portal for Forest Management, Research, and Education

The main objective of this research was to develop a web-based geographic information system (GIS) based on a detailed analysis of user preferences from the perspective of forest research, management and education. An anonymous questionnaire was used to elicit user preferences for a hardware platform and evaluations of web-mapping applications, geographic data, and GIS tools. Mobile GIS was used slightly more often than desktop GIS. Web-mapping applications that provide information to the public and the present research results were rated higher than the forest management application. Orthophotos for general purposes and thematic layers such as forest stand maps, soils, protected areas, cadastre, and forest roads were preferred over highly specialized layers. Tools for data searching, map printing, measuring, and drawing on digital maps were rated higher than tools for online map editing and geographic analysis. The analysis of user preferences was used to design a new multipurpose GIS portal for the University Forest Enterprise. The GIS portal was designed with a three-tier architecture on top of the software library for managing user access, working interactively with digital maps, and managing web map applications. The web map applications focus on tools and geographic information not available elsewhere, specifically timber harvest and logistics, research plots, and hunting game management.

The impact of land use and land cover change on hydrological processes in Brantas watershed, East Java, Indonesia

Assessing the impact of land use and land cover change (LULCC) on hydrology is essential for water resource management. The Brantas watershed contributes about 30% of the water supply of the East Java region. The present rapid pace of land occupation for agriculture and settlements is expected to continue to alter flow processes within the watershed. This study aims to simulate LULCC and its impact on the hydrological processes of the watershed. The long-term impact of LULCC is evaluated using the Soil & Water Assessment Tool (SWAT). The analysis model is calibrated using monthly data series from 1996 to 2005 and then validated using data series from 2006 to 2015. Two editions of maps (2001 and 2015) are then used to calculate the LULCC that took place across this time period. The impacts of LULCC on hydrological processes at the sub-basin level are also evaluated. The results show that the variability of rainfall patterns from 2001 to 2015 strongly affected flow variability. The LULCC from agricultural land to other uses (irrigated rice fields, settlements and forests/plantations) is most evident in three sub-basins (sub-basins 2, 9 and 17). However, each sub-basin may respond differently with respect to the LULCC taking place. The increase in area occupied by each class of land use and cover use (LULC) is not always linear to the observed flow, and widely differing LULC classes may display similar flow responses while classes with similar characteristics may have differing impacts on flows within a sub-basin. In other words, the hydrological processes taking place are too complex to be simplified at the sub-basin level.

From Historic Cartography to Historical Mapping: Creating a Digital Edition of the Gaul/Raczyński Map of Greater Poland (1807−1812)

ABSTRACT The author aims to propose a model digital edition of historic maps using as an example the Gaul/Raczyński map (1807–1812). The digital editions of historic maps elaborated so far vary greatly, from map facsimiles without editorial interference, through georeferenced and mosaicked maps and, finally, to spatial databases. Very rarely they are supplemented with a proper source commentary and editorial work documentation. So far, there has been no edition combining all the above. Thus, the proposed edition connects all those functionalities, illustrating the result with an example of a very interesting nineteenth-century topographical map of part of Greater Poland. It can serve as a starting point for an extensive discussion on the role of historic maps in historical cartography in the digital era.

KMapper: A Field Geological Survey System

The computing power of smart mobile devices has evolved as much as the power of desktop personal computers (PCs). Accordingly, a field geological survey system capable of utilizing the performance of smart devices is needed. Thus, the objective of this paper is to introduce a system with functions to take advantage of the performance of smart devices while meeting the various requirements of a geological survey. The system integrates geographic information system functions and smart sensors to execute field geological surveys effectively and can express various collections on a map. It also includes a map editing function that allows users to edit geological boundaries and areas on a map from the touch-based interface of a smart device. The records collected can be exported for editing of the geological map on a desktop PC. The developed app can replace traditional recording media used in field geological surveying and exploration work. It can be used to acquire location-referenced measurements with smart sensors, making field work more effective.

Tracking Land Use Land Cover changes from 2000 to 2018 in a local area of East Java Province, Indonesia

Abstract Land Use Land Cover (LULC) changes represent human influences on the natural ecosystem. This study aims to analyse such changes in the eastern part of East Java, a region of ± 3320.3 km2. The changes are analysed by comparing two editions of maps (the National Digital Map and Landsat-8). Five subsets are explored to understand the LULC changes caused by the development of: transportation infrastructure; industrial sites; the agricultural sector; tourism; urbanisation; and sub-urbanisation. Regional development from 2000 to 2018 has increased built-up areas by 40.55% (122.5 km2), while paddy fields have increased by 71.08%, and forest plantation areas by 16.03%. Conversely, the development has reduced rural areas by 61.06% (860.1 km2) and water bodies by 54.02% (44.52 km2). The LULC has significantly changed the natural landscape to a human-dominated landscape, which is potentially fragile in the face of the disasters to which the region is prone.

Análise espacial dos casos de dengue e correlação com dados pluviométricos em São Paulo no período de 2015 a 2016

O vírus da dengue é um arbovírus da família dos flavivírus. Há quatro tipos de vírus: DEN (1, 2, 3 e 4), sendo o DEN3 o mais grave. É transmitido pelo Aedes aegypti. As formas clínicas são: a Dengue Clássica, Dengue com Complicações e a Febre Hemorrágica da Dengue. O Brasil é responsável por 70% dos casos da doença nas Américas. O objetivo deste trabalho foram demarcar as localidades que apresentam o maior número de casos de dengue correlacionando com dados pluviométricos no estado de São Paulo no período de 2015 a 2016. A prevalência foi calculada nos munícipios que registraram os maiores números de casos associados aos índices pluviométricos. Para edição de mapas foi utilizado o programa Q GIS 2.18. O estado de São Paulo foi o que apresentou o maior número de casos no país no período de 2015 a 2016 (1.688.688). As maiores prevalências relacionadas com os dados pluviométricos foram registradas em Onda Verde (17.989,9/1445,9mm); São Paulo (17.965,9/1819,4mm); Rio Claro (10.804,7/1435,0mm); Catanduva (8.915,2); Sorocaba (8.815,6/1476,3mm) e Campinas (5.766,2/1793,5mm). Os municípios com os maiores números de casos registrados foram: Onda Verde, São Paulo, Rio Claro, Catanduva, Sorocaba e Campinas. A associação entre a pluviosidade e sorotipo viral provavelmente colaboraram para a elevada prevalência da doença em 2015. Naquele ano a região Sudeste apresentou uma crise hídrica e as pessoas armazenaram água das chuvas em recipientes improvisados aumentando assim a oferta de criadouros do mosquito. Desta forma é muito importante que ocorra o incremento das políticas públicas de prevenção e a conscientização da população ao respeito de medidas para prevenção de criadouros do mosquito vetor. Palavras Chaves: Dengue. Aedes aegypti. Prevalência.

Land use alteration strategy to improve forest landscape structural quality in Radhanagar forest range under Bankura district

Such kind of human necessities restructured the existing landscape pattern which brings imbalance in regional biodiversity. Radhanagar Forest Range (RFR) in Bankura district has been faced same kind of activates since 1960. As a result, forest patch becomes isolated and structurally complex in nature which is an important cause for extinction of wild animal. To control this damage forest department increased forest area through several plantation schemes in vacant or barren land. But plantation areas were not appropriate in the question of structural forest quality in this region. The present study seems that forest structural quality is a vital consideration for balancing biodiversity, in concern of several ecological processes like species movement, connectivity, colonization and edge contrast. Suitable forest patch structure may possible when appropriate areas i.e. forest encroached areas will be select for plantation. To prove this statement, study considers two types of landuse alteration into forest land i) all barren land altered into forest and ii) selected encroached areas altered into forest land in RFR. ArcGIS 10.3 version software is used for technical map editing and preparing these spatial alteration maps. After that several landscape ecological indexes like Total Core Area Index (TCAI), Mean Core Area (MCA) at 300 m specified edge depth, Total Edge (TE), Edge Density (ED), Area Weighted Mean Shape Index (AWMSI), Area Weighted Mean Patch Fractal Dimension (AWMPFD) and Mean Patch Size (MPS) are calculated using FragStat 4.2 version software to compare both spatial alteration forest qualities. Comparison analysis explains that encroached areas alteration into forest land is qualitative to improve forest structural quality. It is interesting to know that less area will be planted in encroached area to get utmost forest structural qualities.

Mapping in Manchu: The Development of Usage of the Manchu Script and Language on Qing Imperial Mapping Projects

The Qing Overview Maps of the Imperial Territories are heterogeneous in nature: from the production process and production techniques to the different languages and scripts in the finished works, each complete edition is different from the others. This article focuses on the heterogeneity found in the usage of the Manchu language, which functions as the descriptive language of the Outer parts of the empire in all editions of the Overview Maps. After the transcriptions of toponyms, synonymous head addition occurs; e.g. in the Manchu transcription hvwang ho bira (Yellow River), both the Chinese character he 河 transcribed in Manchu script as ho and the Manchu bira mean ‘river’. The use of the Manchu language separates the Outer from the Inner regions, but it takes varying forms; Manchu is even written in Chinese characters in several editions, and it conceals a profound variety of languages used in toponyms across the maps. Through a comparison between the different editions, Manchu emerges not merely as a tool to accurately represent geographical space and names, but also as a way to idealize the division of space in the empire.

SAMMI: a semi-automated tool for the visualization of metabolic networks.

Here we present a browser-based Semi-Automated Metabolic Map Illustrator (SAMMI) for the visualization of metabolic networks. While automated features allow for easy network partitioning, navigation, and node positioning, SAMMI also offers a wide array of manual map editing features. This combination allows for fast, context-specific visualization of metabolic networks as well as the development of standardized, large-scale, visually appealing maps. The implementation of SAMMI with popular constraint-based modeling toolboxes also allows for effortless visualization of simulation results of genome-scale metabolic models. SAMMI has been implemented as a standalone web-based tool and as plug-ins for the COBRA and COBRApy toolboxes. SAMMI and its COBRA plugins are available under the GPL 3.0 license and are available along with documentation, tutorials, and source code at www.SammiTool.com. Supplementary data are available at Bioinformatics online.
