The present study attempts to fill this gap by investigating store choice and expenditure flows incorporating both physical and online stores. Based on a representative survey in two German regions, the study employs a revealed-preference approach toward store choice and expenditures taking consumer electronics (CE) retailing as an example. For the analysis of individual shopping behavior, a micro-econometric model, the hurdle model, is applied. Results indicate that channel choice is mainly influenced by spatial, socio-demographic, and psychographic characteristics of the consumers, whilst channel- and store-specific transaction costs – including travel time, delivery time and delivery charges – are main drivers of store choice and expenditures. Furthermore, the cross-channel integration of multi-channel retailers increases the likelihood of such stores being chosen, although this cannot be confirmed for stores providing “click and collect”. It is shown that e-shopping can be integrated into a store choice model, which was originally designed for physical shopping locations only. Both the modeling approach and the results are of significance for retail companies and spatial planning.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":"48 1","pages":"343 - 371"},"PeriodicalIF":0.0,"publicationDate":"2021-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84787148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a major problem faced by the lake is the uncontrolled growth of aquatic vegetation. Monitoring of the dynamics of the condition of the vegetation cover on the waters needs to be conducted periodically as one of the lake management efforts. We propose an Automatic Aquatic Vegetation Extraction method to monitor the dynamics of the condition of the lake's vegetation using multitemporal C-band radar satellite imagery. The method utilizes data from the SAR satellite imagery to ascertain the maximum water boundary, which can be used to distinguish between aquatic and terrestrial vegetation. The Otsu algorithm approach was used to determine the boundary between land and water areas. The method was applied on several dates, employing VV and VH polarizations. The results show that the proposed method could rapidly monitor lakes and their aquatic vegetation from year to year. The overall accuracy of the study varied from 79.48 to 88.46 percent, with an average of 84.4 percent.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":"13 1","pages":"316 - 330"},"PeriodicalIF":0.0,"publicationDate":"2021-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86030497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nearly 90% of electricity needs come directly from Israel, or through Palestinian electricity distribution companies. This situation puts the Palestinian population under continuous pressure, mainly due to the current unstable political situation in the region. The Palestinians have started to explore local alternatives to reduce the impact of Israeli control of this vital sector. Palestine receives about 3,000 hours of sunshine every year, making up an average of 8.2 hours daily, which makes it suitable for investing in solar energy. In this research land-use/land-cover data and a Digital Elevation Model (DEM) are used in a GIS environment while employing land-use/land-cover criteria and topography to produce a site suitability map for harnessing solar energy. The results of the study show that the eastern and southern parts of the West Bank are the most suitable areas for this purpose. The study also finds that the suitable areas for solar energy investment remain under full control of the Israeli Authorities. These areas are categorized as “Area C” according to the Oslo Interim Agreement signed by Israel and the Palestinian Liberation Organization (PLO). This means that the Palestinians need to obtain permission from Israel to work in these areas. Putting an end to the Palestinian- Israeli conflict according to the United Nations resolutions may remove the imposed restrictions to invest efficiently in the solar energy sector.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":"408 16","pages":"256 - 273"},"PeriodicalIF":0.0,"publicationDate":"2021-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23754931.2020.1870540","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72448269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a methodology for measuring WSE in a particularly challenging environment, the Yucatán Peninsula, where cenotes – exposed, water-filled sinkholes – provide an observation point into the critically important regional groundwater supply. In the northeastern Yucatán, elevations are very close to sea level, the area is of low relief, and the near-vertical edges of the walls of the cenotes complicate the use of the so-called “water edge” technique for WSE measurement. We demonstrate how post-processing kinematic (PPK) correction of even a single Real Time Kinematic (RTK) Global Positioning System (GPS) unit can be used to finely register the SfM-derived point cloud, and present evidence from both simulations and an empirical study that quantify the effect of “dip” in SfM-based environmental reconstructions. Finally, we present a statistical analysis of the problem of “thick” or “fuzzy” point clouds derived from SfM, with particular emphasis on their interactions with WSE measurement.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":"49 1","pages":"294 - 315"},"PeriodicalIF":0.0,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84079317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unplanned urban growth alters the natural drainage pattern and the water cycle, consequently, giving rise to floods. The floods are attributed to heavy precipitation but, human activities act as a catalyst in creating an imbalance in the environmental harmony. Predominantly, urban floods in the developing nations are known to affect quite a large population and infrastructure. Nagpur, in Maharashtra, India has been facing hydro-meteorological events in the last decade along with a persistent reduction of natural land and rapid urban growth. The paper attempts to establish a relationship between temporal landcover change for years 1995, 2005, 2015 and increased surface runoff eventually causing urban floods through application of the Soil Conservation Services Curve Number method. These years marked a remarkable urban development in Nagpur hence were considered. The outcome demonstrated a prominent urban sprawl of 12.84 percent and a severe loss of 16.32 percent in natural vegetation between 1995 and 2015. This paper examines the relationship between urban expansion and runoff at the catchment level by integrating land use/cover mapping with the hydrological model. Although the potential impact is expected, this study can further confirm it and facilitate policymakers developing policies to mitigate flooding-caused damages.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":"20 1","pages":"274 - 293"},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78702260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The UNs Sustainable Development Goals (SDG) seek to provide universal access to electricity services by 2030. In Brazil, with the implementation of social programs such as “Light for All,” access to electricity has been extended to more than 15 million people in recent years. However, many residential areas, mainly in the Brazilian Amazon, still lack access to the electricity supplies due to factors such as low population density, topography, long distances, lack of infrastructure, among others. This paper intends to elaborate and analyze hypothetical scenarios to investigate ways that allow planning and electrification strategies in the municipality of “São Gabriel da Cachoeira” located within the Brazilian Amazon. The OnSSET – a set of modeling tools based on QGIS – was applied with open access data. The aim was to identify an ideal combination of electrification options by considering network extensions, mini-grid and/or autonomous, solar, wind, hydroelectric and diesel solutions depending on the availability of resources. Our results show that photovoltaic solutions are the most adequate for the region, mainly because of the region’s high solar radiance, associated with low wind speeds and high diesel costs.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":"30 1","pages":"239 - 255"},"PeriodicalIF":0.0,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83850344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Geoinformatics plays a vital role in providing tools to assess coastal vulnerability. Recent improvements in drone technology offer new opportunities for collecting data.

This research compares the use of drone-derived digital elevation models (DEMs) created from a DJI Phantom 4 Pro drone with airborne LiDAR data to analyze sea-level rise in Essex, Massachusetts. To evaluate the best method of calibrating drone elevation data to the local environment, three different Ground Control Point (GCP) methods were evaluated: surveyed GCPs, LiDAR-derived GCPs, and the NAVD88 sea-level (0-value) of the LiDAR data. The three drone-derived DEMs were compared with a LiDAR DEM through two methods: 1) comparing how well the DEMs measured the elevation of surveyed GCPs, and 2) how well the DEMs modeled five different scenarios of sea level rise compared with a LiDAR DEM. Results showed that two of the calibration methods performed well; the surveyed GCP derived drone DEM and the LiDAR NAVD88 sea-level (0-value) derived drone DEM.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":"37 1","pages":"331 - 342"},"PeriodicalIF":0.0,"publicationDate":"2021-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87279351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A good understanding of its associations with relevant factors is essential for an effective reduction in PTB risk. This study explores the spatially varying relationships between PTB and demographic, socioeconomic, and behavioral factors in the state of Georgia, USA using Geographically Weighted Logistic Regression (GWLR). The results show the relationships between PTB and factors vary over space, and the spatial patterns in the varying relationships are related to the socioeconomic and urbanization characteristics of the communities where the births were located. For example, PTB has significant positive relationships with black mothers and single mothers, and significant negative relationships with maternal education in the majority of Georgia, but such relationships are insignificant in small portions of rural Georgia with low socioeconomic status (SES). PTB has significant positive relationships with maternal age and parity, and significant negative relationships with female births in small portions of Georgia, particularly in the Atlanta Metropolitan Area, while in larger portions of rural Georgia with overall low SES, those relationships are not significant. Thus, health prevention and intervention policies should be tailored to address the locally important factors to reduce PTB risk.","PeriodicalId":36897,"journal":{"name":"Papers in Applied Geography","volume":" 42","pages":"217 - 237"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/23754931.2020.1866651","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72384908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
