As a vital indicator for measuring urban development, urban areas are expected to be identified explicitly and conveniently with widely available dataset thereby benefiting the planning decisions and relevant urban studies. Existing approaches to identify urban areas normally based on midresolution sensing dataset, socioeconomic information (e.g. population density) generally associate with low-resolution in space, e.g. cells with several square kilometers or even larger towns/wards. Yet, few… 

Figures and Tables from this paper

Population spatialization and synthesis with open data

TLDR
The road network in OpenStreetMap is used to identify and delineate parcel geometries, while crowd-sourced points of interest are gathered to infer urban parcels with a vector cellular automata model, and the published census data is used for synthesizing population attributes with a previously developed tool Agenter.

Delimitating the Natural City with Points of Interests Based on Service Area and Maximum Entropy Method

TLDR
This paper suggests aggregating the natural city boundary from the service area polygons of points of interest based on Reilly’s Law of Retail Gravitation and the maximum entropy method, since most points of interests provide services for surrounding communities, reflecting the vitality in a bottom-up way.

TLDR
A geographic representation that views cities as a whole is developed, which fundamentally differs from existing geometry-based geographic representations and can be applied to any design or pattern, such as carpets, Baroque architecture and artifacts, and fractals in order to assess their beauty.

Adaptive simplification of GPS trajectories with geographic context – a quadtree-based approach

TLDR
This study proposes a novel two-stage adaptive trajectory simplification method embedding spatial indexing, enrichment, and aggregation in an integrated process that can still preserve inter-trajectory distances between original trajectories and simplified ones, while significantly reducing the computing time.

Big/open data in Chinese urban studies and planning: A brief review

TLDR
An overview of urban big data studies from the institutional, academic, and practical perspectives is provided, Particularly, it elaborates a number of research projects carried out by Beijing City Lab, a virtual research community dedicated to urban dynamics studies.

PolySimp: A Tool for Polygon Simplification Based on the Underlying Scaling Hierarchy

TLDR
PolySimp is developed, a tool that integrates the mentioned four algorithms for polygon simplification based on its underlying scaling hierarchy, and the British coastline was selected to demonstrate the tool’s usefulness.

Integrating variable energy resources, notably solar and wind, requires better understanding of where, when and how much of variable resources are available. China's ambitious solar energy

FracL: A Tool for Characterizing the Fractality of Landscape Gradients from a New Perspective

TLDR
These new fractal metrics and the developed tool can be expected to facilitate the fractal characterization of the patterns of gradient landscapes and the understanding of landscape dynamics from a new perspective.

Mining urban land-use patterns from volunteered geographic information by means of genetic algorithms and artificial neural networks

TLDR
Results show that the delineation of urban areas by means of the presented methodology depends strongly on location, which is an essential aspect of its fitness for use in specific applications, such as planning tasks.

Comprehensive delimitation and ring identification on urban spatial radiation of regional central cities: Case study of zhengzhou

In China and a number of other countries, recent years have seen a prevailing trend in collective and cooperative urban development, transforming individual cities to polycentric metropolis. Such a

Automated identification and characterization of parcels with OpenStreetMap and points of interest

TLDR
This work proposes a method to automatically identify and characterize parcels using OpenStreetMap (OSM) and points of interest (POI) data and adopts a vector-based cellular automata model to select urban parcels in China.

Modelling sustainable urban development by the integration of constrained cellular automata and GIS

TLDR
How cellular automata (CA) can be extended and integrated with GIS to help planners to search for better urban forms for sustainable development is discussed.

Retrieving Spatial Policy Parameters from an Alternative Plan Using Constrained Cellular Automata and Regionalized Sensitivity Analysis

TLDR
A novel approach incorporating constrained cellular automata and regionalized sensitivity analysis, a method for global sensitivity analysis to calculate the realization possibility and identify the spatial policy parameters for an alternative plan is proposed.

Scaling of geographic space from the perspective of city and field blocks and using volunteered geographic information

TLDR
An analogy between a country and a city (or a city or geographic space in general) and a complex organism like the human body or the human brain is drawn to further elaborate on the power of this block perspective in reflecting the structure or patterns of geographic space.

Restoring urbanization process in China in the 1990s by using non-radiance-calibrated DMSP/OLS nighttime light imagery and statistical data

Since current administrative unit-based urban land area statistical data in China lack enough spatial information, the urbanization process research at large scale cannot be effectively supported.

A GIS-Based Irregular Cellular Automata Model of Land-Use Change

TLDR
An alternative cellular automata model is proposed, which relaxes the traditional CA regular square grid and synchronous growth, and is designed for representations of land-use change in rural-urban fringe settings.

Timely and accurate national-scale mapping of urban land in China using Defense Meteorological Satellite Program’s Operational Linescan System nighttime stable light data

Abstract Urban land accounts for a small fraction of the Earth’s surface area but rapid increases in urban land have a disproportionate influence on the environment. China is a living laboratory in
