Introduction
I am currently working with Discrete Global Grid Systems (DGGS) to integrate big geospatial data and analyze it with artificial neural networks.

Article
Regional development differences are universal economic development process problems of countries around the world. Unbalanced development theories have been used to interpret population migration; conversely, population migration patterns can also reflect unbalanced regional development. Inspired by the growth pole and pole-axis theories, we infer...
Article
Spatial prediction of any geographic phenomenon can be an intractable problem. Predicting sparse and uncertain spatial events related to many influencing factors necessitates the integration of multiple data sources. We present an innovative approach that combines data in a Discrete Global Grid System (DGGS) and uses machine learning for analysis....

Regional development differences are a universal problem in the economic development process of countries around the world. In recent decades, China has experienced rapid urban development since the implementation of the reform and opening-up policy. However, development differs across regions, triggering the migration of laborers from underdevelop...
Article
Night-time light (NTL) data shows a high correspondence with human activities. Recent studies also found that the NTL responds to holidays, and that light values often peak at festival times. However, there are few studies on the different patterns of light change caused by different cultural events. Here, we examined the impacts of festivals on NT...

Night-time light (NTL) images have been proved as a type of reliable data source to map urban expansion. In this paper, to investigate the potential of using multi-source NTL images at near 100 m resolution to detect urban expansion, we use a Luojia1-01 (LJ1-01) image in 2018 and an International Space Station (ISS) night-time image in 2010 in Wuha...

From time to time the popular media draws attention to hate crimes and hate groups, evoking images of Nazi-Germany and the rise of fascism. The geographic association between hate groups and hate crimes is uncertain. In this research we ask whether hate crimes are co-located and correlated to the presence of hate groups to explore a potential assoc...

Launched on 2 June 2018, Luojia-1 satellite records night-time light imagery at 130 m resolution, which is higher than most of the existing night-time light images to date. This study evaluated radiometric and spatial properties of the Luojia-1 satellite imagery for cities of Los Angeles, Wuhan and Rome as well as the change detection capability fo...

Studying the impact of social events is important for the sustainable development of society. Given the growing popularity of social media applications, social sensing networks with users acting as smart social sensors provide a unique channel for understanding social events. Current research on social events through geo-tagged social media is main...
Conference Paper
With more than 50% of the world’s population now living in cities, monitoring urban areas is of utmost importance. Synthetic Aperture Radar (SAR) is a very useful tool for monitoring urban areas because artificial objects, like buildings, typically appear bright and stable in SAR images. By using the coherence, which is the complex correlation betw...

In this study, we analyzed the night-time light dynamics in Iraq over the period 2012–2017 by using Visible Infrared Imaging Radiometer Suite (VIIRS) monthly composites. The data quality of VIIRS images was improved by repairing the missing data, and the Night-time Light Ratio Indices (NLRIs), derived from urban extent map and night-time light imag...
Article
This paper argues that many of the existing cluster algorithms employed by practitioners are too unspecific for archaeological purposes. Based on a large landscape archaeological dataset a cluster algorithm for archaeological applications is developed. It accounts for shortfalls in generic cluster algorithms like the difficulty to cluster point clo...

Urbanization is a set of interrelated processes; the most visible among them are changes in the built-up environment. We relate those changes to human activity as expressed by online social media messages. This approach might shed light on urban dynamics currently intractable through existing datasets and methodologies. Microwave remote sensing ima...

China's social media platform, Sina Weibo, like Twitter, hosts a considerable amount of big data: messages, comments, pictures. Collecting and analyzing information from this treasury of human behavior data is a challenge, although the message exchange on the network is readable by everyone through the web or app interface. The official Application...

In this geo-statistical analysis of change detection, we illustrate the evolution of the built-up environment in Shanghai at the street-block level. Based on two TerraSAR-X image stacks with 36 and 15 images, covering the city centre of Shanghai for the time period from 2008 to 2015, a set of coherence images was created using a small baseline appr...

We address the processing of interferometric TerraSAR-X and TanDEM-X spotlight data. Processing steps necessary to derive interferograms at high spatial resolution from bi- and monostatic satellite images will be explained. The spotlight image mode is a beam steering technique focusing the antenna on a specific ground area. This results in a linear...

Using high-resolution SAR data stacks, a large amount of persistent scatterers (PS) can be found in urban areas, which are used for very detailed surface deformation monitoring. However, in dense urban areas, many of these points consist of more than one dominant scatterer in elevation direction. Using tomographic SAR, points with more than one sca...
