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.
