Consequently, this study applied regression analysis using r software and QGIS mapping to evaluate how COVID-19 infections are impacted by population dynamics, urbanisation, area temperature and tourism activities in Namibia. Study results revealed that, COVID-19 transmission is positively associated with urbanisation and negatively associated with temperature. Area population size is not associated with COVID-19 transmission. To reduce COVID-19 infections in Namibia, efforts need to be directed at minimising social and economic contact activities, particularly in urban areas. The Namibia society is also encouraged to adhere to the recommended COVID-19 public health measures such as social distancing of 1.5 meters apart and wearing of face masks in public spaces.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45007297","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}

Practical location data are scarce in Ghana and most of Sub-Sahara Africa where cities are typically characterized by informal settlements and a lack of standard address system. The problem is compounded by limited use of indigenous languages for travel services even though the majority of the population lacks familiarity with English. This study attempts to address these issues by developing a mobile app which takes advantage of local location data integrated into OpenStreetMap through Mapbox to provide location and travel planning services in English and indigenous Akan language The developed mobile app called ‘myTroski’ provides key capabilities to describe landmark information, find nearby landmarks, search and find, travel routing and planning, GPS assisted map use, and text and audio assisted navigation. The study shows the formalizing and modernizing location data from paratransit Trotro service and landmarks to mainstream local address systems.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49539219","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 aggregated opioid overdoses to street segments and applied the optimized hot spot analysis to identify areas with significant high overdose rates. Multiple spatial regression models were used to explore the ecological risk factors potentially associated with the spatial variations of the epidemic. The results suggest an overall clustered pattern of opioid overdoses with all overdose incidents concentrated in less than 8% of all the street segments. The consecutive hot spots largely overlapped with the most disadvantaged inner-city neighborhoods in Louisville. Regression results provided statistical evidence regarding the effects of socioeconomic correlates including uninsured, vacancy rates, and criminal activity. The spatial discrepancy between the overdose hot spots and lack of medical facilities or hospitals in the disadvantaged neighborhoods points to the critical issue of health inequity.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45955816","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 initial construction of the border fence is thought to have impacted lower socio-economic residents given its location and exacerbated flooding along the Rio Grande. I examine inundation using Nays2DFlood to model flooding extents in fence and non-fence conditions Results are then subtracted from each other to determine the impact of the border fence. I found that water depths do not differ between fence and non-fence conditions, but the fence plays a significant role in decreasing water velocities at the fence line and increasing water velocities at fence gaps and flood margins. Given on-the-ground observations by residents during flood events, this decrease in velocity can pick up debris and trap it against the fence, prolonging flood inundation times and thus delaying flood recessional flows. In addition, these conditions may lead to dangerous water velocity conditions near populated areas.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46252838","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}

This work focuses on drought analysis using a high-resolution remote sensing and meteorological dataset from MODIS’s NDVI and LST to evaluate the Spatio-temporal distribution drought events and intensities in three physiographic regions of the USA from 2000–2019. Results were compared with other remote-sensing-based drought indices, such as the temperature condition index (TCI), Vegetation Health index (VHI), and it was observed that the VCI and VHI, which was a combination of vegetation and meteorological information, had a strong correlation with precipitation data than the NDVI-derived VCI. The results demonstrated the severity of vegetation stress and extreme droughts in 2000, 2006, 2011, and 2012. The long-term agricultural drought situation and compared with other drought indices, reveals a good agreement as to the TCI, VHI, and precipitation anomalies also decreased significantly.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41586311","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 popular oak species in recent decades has been the Nuttall oak (Quercus texana). A total of seven Nuttall oaks were scanned using a terrestrial LiDAR scanner and modeled for comparison to manual measurements. These trees were then destructively sampled in place to measure their above-ground biomass. The biomass data were compiled and statistically compared against digital models of each tree that were created from the LiDAR scans. This resulted in a Pearson coefficient of .977 and linear regression R2 value of .99 for the LiDAR derived measurements predictive ability in comparison to the manually derived measurements. This indicates an ability of this ground based LiDAR model to predict both the linear dimensions and volumetrics of the standing specimens without the need for such labor intensive and expensive sampling given the sensitivity and value of urban forests.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41713640","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}

Discovering interesting or useful patterns from these spatiotemporal data is referred to as spatiotemporal data mining. These patterns could be unordered, totally ordered or partially ordered based on the temporal ordering. This work focusses on the totally ordered patterns or sequential patterns from spatiotemporal event database. Spatiotemporal event sequence miner finds sequence of events that overlaps spatially and temporally. Traditional approaches discover patterns that are frequent in the entire dataset. In this work a clustering-assisted approach to find regionally or locally frequent spatiotemporal pattern is proposed. The proposed Clustering assisted Regional Spatiotemporal Event Sequence (CReST) mining approach overcomes the bias caused by uneven distribution of spatiotemporal events while mining patterns. Chicago crime dataset is used for evaluating the proposed approach with traditional sequence mining algorithm.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42727072","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 high neighborhood social vulnerability was associated with greater risk of infection especially for persons over age 25, for Hispanics and Asians. High prevalence rates were significantly and strongly associated with all major factors of the social vulnerability in early stage of the pandemic, especially with the factor associated with Hispanic and immigrant population.

The results show a larger persistence and concentration of woody vegetation in the East Coast (the Scotland District) of Barbados. Woody vegetation cover declined by approximately 11 km2 from 2001 to 2015, and 1.5 km2 from 2015 to 2019. Intensity analysis showed that total observed change in the landscape was slow in the first time interval but fast in the second. Categorical gain-loss showed a systematic targeting between woody vegetation and other vegetation. Built-up and woody vegetation, however, systematically avoided each other. Woody vegetation remained active in both time intervals but the intensity of change was larger in the second interval. In conclusion, the systematic targeting between woody vegetation and other vegetation (mainly agriculture) provides a focus for management, conservation and spatial expansion of the latter.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48993116","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}

In this study, we investigated the relationship between destinations in cities and walking behaviors in national and provincial capital cities in China based on a nationwide smartphone dataset. We identified destinations that were strongly and consistently associated with walking behaviors based on geographic information systems (GIS) spatial analysis. Results from this study suggest that certain components, especially parks, rivers, running tracks, of the built environment were positively associated with walking behaviors. Parks were consistently associated with more frequent walking behaviors while rivers were associated with longer walking trajectories. Findings from this study help better understand to what extent urban destinations influence physical activities and support evidence-based urban planning and health promotion in cities.","PeriodicalId":43062,"journal":{"name":"International Journal of Applied Geospatial Research","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48957183","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}
