Complexity-based matching between image resolution and map scale for multiscale image-map generation

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, 2021; 35 (10)

An image-map is a compromise between an image and a map. The quality of such maps is affected by several factors, such as (a) the matching between the......

Detecting spatiotemporal extents of traffic congestion: a density-based moving object clustering approach

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, 2021; 35 (7)

Traffic congestion detection poses challenges in spatiotemporal data mining and intelligent transportation research. Existing studies primarily detect......

Using information entropy and a multi-layer neural network with trajectory data to identify transportation modes

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, 2021; 35 (7)

Residents' trajectory data denote their instantaneous locations along their movements. Mobility research that applies trajectory mining techniques to ......

Movement-aware map construction

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Map construction algorithms attempt to derive a spatial graph representing a road network from GPS-sampled movement trajectories. Existing methods com......

Understanding the modifiable areal unit problem in dockless bike sharing usage and exploring the interactive effects of built environment factors

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Understanding the influence mechanisms of dockless bike-sharing usage is essential for land use planning and bike scheduling strategy implementation. ......

A topic model based framework for identifying the distribution of demand for relief supplies using social media data

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Natural disasters have caused substantial economic losses and numerous casualties. The demand analysis of relief supplies is the premise and basis for......

Applying frequent-pattern mining and time geography to impute gaps in smartphone-based human-movement data

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Though GPS-based human trajectory data have been commonly used in travel surveys and human mobility studies, missing data or data gaps that are intrin......

A hybrid approach to building simplification with an evaluator from a backpropagation neural network

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Research has developed numerous algorithms to simplify building data. Each algorithm has strengths and weaknesses in addressing shape characteristics,......

Compliance and containment in social distancing: mathematical modeling of COVID-19 across townships

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

In the early development of COVID-19, large-scale preventive measures, such as border control and air travel restrictions, were implemented to slow in......

Tagging the main entrances of public buildings based on OpenStreetMap and binary imbalanced learning

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Determining the location of a building's entrance is crucial to location-based services, such as wayfinding for pedestrians. Unfortunately, entrance i......

A constraint-based approach for identifying the urban-rural fringe of polycentric cities using multi-sourced data

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Studies on urban-rural fringes, which represent regions facing various urbanization problems caused by rapid expansion, have steadily increased in rec......

Sparse reconstruction with spatial structures to automatically determine neighbors

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Previous research has tended to use a global threshold of proximity to determine neighbors, neglecting spatial heterogeneity. Flexible thresholds impl......

Spatiotemporal effects of climate factors on childhood hand, foot, and mouth disease: a case study using mixed geographically and temporally weighted regression models

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Hand, foot, and mouth disease (HFMD) is a global infectious disease severely threatening children's health. It has been recognized that climate factor......

Delineating urban job-housing patterns at a parcel scale with street view imagery

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Empirical data are limited to decipher where people live and work in large cities; however, neighborhood information, such as street view image, is ri......

SNN_flow: a shared nearest-neighbor-based clustering method for inhomogeneous origin-destination flows

期刊: INTERNATIONAL JOURNAL OF GEOGRAPHICAL INFORMATION SCIENCE, ; ()

Identifying clusters from individual origin-destination (OD) flows is vital for investigating spatial interactions and flow mapping. However, detectin......
