Visualising population distribution with choropleth maps
Choropleth maps are among the oldest and still one of the most frequently used techniques for visualising quantitative data, such as population density. Today, each geographic information system (GIS) has a plethora of options for categorising data into classes for choropleth maps. Each option has its pros and cons, depending on the data and the use case. This paper presents the results of a user study to assess the suitability of different data …
Quantifying informal public transport using GPS data
Informal public transport modes transport the largest number of passengers in most developing countries. Despite its significance, limited information is available on the extent of its operations, and passenger counts alone do not provide sufficient insight into network coverage or passenger turnover. GPS tracking has emerged as a valuable tool, yet its potential for understanding minibus taxi operations at the road segment level remains underexp…
Measuring geographic accessibility in data poor rural areas by augmenting the road network with a triangular irregular network – A case study in the O.R. Tambo District Municipality of the Eastern Cap…
Travelling long distances to access public service facilities is costly and time consuming, especially to those who suffer the burden of poverty and deprivation. Assessing accessibility based on route-based distances does not work well in rural areas of Africa where people often travel along footpaths and dirt roads (in and out of vehicles) that are not mapped, not necessarily well-defined, could vary based on the season or change over short peri…
A street segment analysis of crime in a township
Street segments as a micro-level unit of analysis have become increasingly popular in spatial crime research with a plethora of studies having shown how crime spatially concentrates at this spatial scale. The vast majority of this research has, however, emanated from the United States and other ‘Westernized’ cities, with little attention on less developed contexts. Developing countries have different structural and design conditions from develope…
