Capabilities for collecting and storing data on mobile objects have increased dramatically over the past few decades. A persistent difficulty is summarizing large collections of mobile objects. This article develops methods for extracting and analyzing hotspots or locations with relatively high levels of mobility activity. We use kernel density estimation (KDE) to convert a large collection of mobile objects into a smooth, continuous surface. We then develop a topological algorithm to extract… 
Discovering Hotspots in Dynamic Spatial Networks Using Mobility Data
TLDR
A dynamic spatial network (DSN) considering evolving characteristics to discover hotspots (collective gathering, traffic congestion, and so on) in urban road networks is proposed and a generate-and-test framework for hotspot detection is proposed.
Global and individual mobility pattern discovery based on hotspots
TLDR
This paper studies the human mobility trajectories during 22 days for 3474 individuals collected at the core of a metropolitan Long Term Evolution (LTE) network in China and finds that the global mobility patterns have higher occurrence probability in the morning, which indicates that people in a city tend to share the common commuting routes.

TLDR
A two-phase clustering approach is proposed to detect urban hotspot with taxi trajectory with spatiotemporal hierarchical density-based spatial clustering of applications with noise, which is essential for understanding the evolution of urban hotspots over time.
Exploring geographic hotspots using topological data analysis
TLDR
A visual analytics system to support analysts in hotspot analysis and abstraction using SFT is presented, and the merit of the proposed SFT‐based methodology on two crime datasets is demonstrated.
Identification and analysis of urban influential regions using spatial interaction networks
TLDR

Stigmergy-Based Modeling to Discover Urban Activity Patterns from Positioning Data
TLDR
This work exploits positioning data to identify high density areas (hotspots) and characterize their activity over time, providing a similarity measure exploitable by clustering techniques and cluster days according to their activity behavior, discovering unexpected urban activity patterns.
Detecting Permanent and Intermittent Purchase Hotspots via Computational Stigmergy
TLDR

Exploring Spatial-Temporal Patterns of Urban Human Mobility Hotspots
TLDR
This study aims to characterize the urban spatial-temporal dynamic from the perspective of human mobility hotspots by using mobile phone location data and proposes a workflow to identify human convergent and dispersive hotspots that represent the status of human Mobility in local areas and group these hotspots into different classes according to clustering their temporal signatures.
Ranking places in attributed temporal urban mobility networks
TLDR
The spatio-temporal characteristics of “hotspots” of different types of socio-economic activities as characterized by recently developed attribute-augmented network centrality measures within the urban OD network are studied.

Algorithms for Extracting Correct Critical Points and Constructing Topological Graphs from Discrete Geographical Elevation Data
TLDR
This paper presents new algorithms for extracting features and constructing the topological graphs using the features and provides an algorithm that converts the surface network to the Reeb graph for representing contour changes with respect to the height.
Understanding intra-urban trip patterns from taxi trajectory data
TLDR
The authors' Monte Carlo simulation results closely match to the observed patterns and thus validate the proposed model, which argues that in a single-core urban area, the geographical heterogeneity and distance decay effect improve each other when influencing human mobility patterns.

TLDR
The results show that the differentiated structures of road networks can be evaluated by the measure of entropy; predefined connection patterns of arterial roads can be identified and quantified by the measures of ringness, webness, beltness, circuitness, and treeness.
