This channel would release Beijing, or the whole China, micro-data and maps (e.g. road networks, parcels, human mobility, historical city maps) for the BCL research fellows and external researchers. There are three levels of data access, free download, email request, and shared among research fellows / student members.
Our released datasets are stored in DropBox. We would like to recommend you setup DropBox for downloading the datasets to your account. This is helpful when the download is temporally unavailable due to too many requests.

According to our previous bibliometrics study (城市规划的知识产出、消费与网络), the large Chinese cities have been attracted over much attention from researchers, and most of small cities in China are not well studied. For alleviating this situation, we are releasing the emerging new data (open data) for a small city in North East China, Yichun, which is experiencing population shrinking (for more, see the BCL project 15 Shrinking Cities, http://www.beijingcitylab.com/projects-1/15-shrinking-cities/). We hope this effort may shed light on the research for Shrinking Cities in China as well as potentially improve the quality of life of this small city through the lends of more studies and better decision making.

We are sharing the urban areas interpreted from night time images DMSP-OSL and MODIS. The data provided by Prof Xiaoping Liu from Sun Yat-sen University cover the whole China for 2000, 2005 and 2010. Please cite the attached paper in case you use the data for research.
We gathered bus stops of most Chinese cities in 2013. We have used this data for bus coverage estimation. Bus coverage ratio of each city, a key indicator of 公交都市(交通部), was calculated by dividing the area of urban land overlaid with bus service coverage area with the total urban area of the city. Please see "1 Bus coverage of Chinese cities" for details (http://www.beijingcitylab.com/ranking/).
We are now sharing the bus stops of China which we used for our study. Please cite our recent paper in your publication using our data (attached below).
Please address your data request to Mr Miaoyi Li (email: email@example.com) for the ShapeFiles dataset of bus stops. We would be always ready to provide the full dataset.
Prof Bin Jiang is willing to share points of interest in Germany, France and UK with all BCLers and those who are paying attention to us. Please direct visit his portal at ResearchGate for the data downloading.
All these data have been used in the previous work:
Citation to the paper is welcomed.
If you meet a problem on data downloading from ResearchGate, please address your email to beijingcitylab(at)gmail(dot)com and we would send you a Baiduyun link directly. Please keep in mind that the data on ResearchGate may be updated by Prof Jiang, and those updates may not included in the Baiduyun link.

City-related data, with a rapid growth in amount, is involving various aspects of everyone’s daily life. City researchers are devoting efforts to deepen our understanding of city based on unorthodox data. However, as most data are too precise and thus, sharing these data may offend the benefits of the original data holders. In such context, focusing on the extent of China, we initiated SinoGrids, a platform for the sharing of micro-scale data based on a 1km fishnet. Guidelines and Tools are provided for the micro-scale data holders to downscale their original datasets onto the 1km fishnet and upload to the platform of SinoGrids, forming a crowdfunding platform for basic data in China.
In terms of the scale, 1km2 is a scale both available for regional analysis between cities and internal studies of a certain city. Also, SinoGrids will share its data in the crowdsourcing way. The collected datasets, from either donations of scholars or open internet resources, (e.g. Weibo, taxi trajectory, road junctions, bus stops, photos) will be summarized to the fishnet and made public on SinoGrids data platform. In other words, the total amount of Weibo, Flickr photos and bus stops, etc. per 1km2 according to the fishnet will be displayed on the platform. The platform will also maintain the most and complete indexes and data guidelines for the convenient implementation of the public. On the one hand, data holders donate their micro-scale data through SinoGrids. On the other hand, they can realize regional analysis, urban studies, city planning consultation, and public participation under the guidelines of SinoGrids. SinoGrids will be a public and open platform for city-related data, with a hope to provide complete and transparent data support for quantized researches and regional analysis.

Four ShapeFile layers are included in the package:
(1) Road junction density
(2) Population density (based on BCL Data 19)
(3) Vector cellular automata
In addition, you can download BCL Data 16 DMSP/OLS interpreted urban areas of China in 2008 (night light images), and urban areas reflected by BCL Data 17 Impervious area of China (actually urban areas overestimated by the data).
