The problem of soil pollution by heavy metals has been receiving an increasing attention in the last few decades. Geostatistics module in ArcGIS, could not however efficiently simulate the spatial distribution of heavy metals with satisfied accuracy when the spatial autocorrelation of the study area severely destroyed by human activities. In this study, the classification and regression tree (C...

INTRODUCTION In Australia, colorectal cancer is the second most commonly diagnosed cancer and cause of death from malignant diseases, and its incidence is rising. The aim of this article was to present an analysis of National Bowel Cancer Screening Program (NBCSP) data for rural and remote South Australia (SA), in order to identify geographical areas and population groups that may benefit from ...

In this paper, we took the urban roads in Changsha downtown areas as an example to identify green view index (GVI) of based on street images (SVIs). First, road network information was obtained through OpenStreetMap, and coordinate sampling points processed using ArcGIS. Secondly, SVIs were downloaded from Baidu Map according latitude longitude coordinates points. Moreover, semantic segmentatio...

BACKGROUND Physical activity is an important determinant of health. Walking is the most common physical activity performed by adults and the presence of sidewalks along roads is a determinant of walking. Geographic information systems (GIS) can be used to measure sidewalks; however, GIS sidewalk data are difficult to access. The purpose of this study was to present a new GIS method for measurin...

BACKGROUND Collision geocoding is the process of assigning geographic descriptors, usually latitude and longitude coordinates, to a traffic collision record. On California police reports, relative collision location is recorded using a highway postmile marker or a street intersection. The objective of this study was to create a geocoded database of all police-reported, fatal and severe injury c...

Map projection on-the-fly capability allows natural resource GIS analysts to geoprocess spatial data layers referenced to different map coordinate systems. This study’s primary objective was to provide examples of spatial measurement differences that can result when point, line, and polygon natural resource spatial databases are referenced to different map coordinate systems and are used for a ...
