Geographic Information Systems (GIS) analysis of high‐resolution multibeam bathymetry and remotely operated vehicle data to model rockfish habitat preference

Abstract Lake disappearance as a natural stage of evolution of lakes is an extremely important issue in the landscape and ecosystem research context. Studies of the changes that occur in the lake landscape, characteristic in the northern part of Poland, are aimed at defining the cause and forecasting the results. The possibilities of the Geographic Information Systems (GIS) were used in this paper to analyse and visualise the process of lake disappearance in the Iława Lakeland Landscape Park. GIS technologies which primarily are used for gathering, storing, processing and presenting spatial data have been used to interpret changes in lakes coverage over a period of 100 years. The analysis were based on data bases and cartographic former maps such as hydrographic maps, attribute data and bathymetric plans. The data was gathered by transfer from different geoportals, next vectorised, and then preprocessed. Former maps were rectified. The lake disappearance process was presented in several forms: lake cards, animations and interactive map. Basing on the GIS analysis about lake disappearance in Iława Lakeland Landscape Park it was possible to state that lakes are disappearing in rate of 3.99 ha a−1.

Care System

The possibilities of geographic information systems (GIS) application in the context of reforming the health care system of Ukraine and medical support of the Armed Forces of Ukraine have been studied. GIS helps to provide timely medical care in emergencies – natural disasters, adverse weather conditions, military conflicts, riots, when decisions must be rapid. GIS-analysis increases the efficiency of both routine tasks and planning at all levels of the government. The experience of using GIS at different stages of health care reform and development in the world's leading countries shows that the widespread use of geospatial technologies can significantly improve the management of data, material and human resources, understanding of factors and impacts on health care. The modern challenges require the health care system of our country and medical support of the Armed Forces of Ukraine to use advanced information technologies for the collection, management, analysis, visualization and dissemination of data that can largely provide the geographical information systems. Without GIS, it would be difficult to imagine effective work in crises, emergencies or in the context of military conflict, the successful operation of that depends on people's lives and health. The article studies the possibilities of using geographic information systems (GIS) in the context of health care reform in Ukraine. The experience of using GIS at different stages of health care reform and development in the world's leading countries shows that the widespread use of geospatial technologies can significantly improve the management of data, material and human resources, understanding of factors and impacts on health care. GIS analysis increases the efficiency of both routine tasks and planning at all levels of management. It would be difficult to imagine effective work in crises, emergencies or during military conflicts of many organizations, on the successful performance of which people's lives and health depend, without using GIS. Today's challenges require our country's healthcare system to use advanced information technology to collect, manage, analyze, visualize, and share data that geographic information systems can provide to a large extent. The article considers examples of problems and tasks that can be solved by certain GIS tools. The challenge staysin working with data that is often provided on paper or in formats that are hard to process and store. This organizational and financial problem will continue until health facilities are equipped with necessary hardware, software and staff training. Regarding data that has a spatial component, this issue can be solved with the help of server GIS and geoportal technology, which are able to organize the work with data, sharing for large number of people, data collection, and availability of geospatial services for use in any time and place. Equally promising in the field of health care is the use of GIS-analysis tools that allow to obtain the data needed to make informed decisions, forecast and plan further activities in the short and long term. Ukraine is on the way to strengthening the informatization of the health care system. GIS should play an important role in this process as the main tool for working with spatial information.

Geographic Weighted Regression

The research conducted for this study presents a Geographic Information Systems (GIS) and spatial analysis to understanding and modelling the impacts of a new competitor on the sales of established businesses within similar markets. Data for this analysis was provided by Canadian Tire Corporation (CTC).This study will outline and create trade areas for all stores in the Part Source network to determine which stores will be the focus of this study. Once focus stores have been determined, sales data was analyzed in two ways. The first analysis was conducted to determine the distance decay effects of the new competitor on sales. The second analysis utilized geographic weighted regression (GWR) models on expenditure and vehicle data.

Occurrence Data

Mapping geographic ranges of species and higher taxa using Geographic Information Systems (GIS) produces quantitative data on spatial and temporal changes in geographic ranges. The primary advantage of GIS analysis is that it has the capacity to utilize large amounts of occurrence data of species to produce quantitatively constrained geographic range reconstructions that are amenable to statistical analysis. The basic steps in GIS range reconstruction are database assembly (including taxonomic, geographic, and stratigraphic information for each specimen), mapping of localities of species on modern continental configuration, rotation of occurrence data of species onto paleocontinental reconstructions, and reconstructions of geographic ranges. GIS analysis of ranges of species has been used to assess faunal dynamics of the Late Devonian Biodiversity Crisis, and three case studies are presented here. In these case studies, GIS-derived ranges of species are used to assess the relationship of biogeography with sea level, speciation and extinction rates, mass extinction survival, speciation mode, and invasive history of taxa. These case studies represent a subset of the potential for GIS analyses to examine paleontological patterns and contribute to improving understanding of the interaction between paleobiogeography, paleoecology, and evolution in the fossil record.
