Abstract

In this research we use data from a number of different sources of satellite imagery. Below we describe and visualize various metrics of the datasets being considered. Satellite imagery is retrieved from Google earth which is supported by Data SIO (Scripps Institution of Oceanography), NOAA (National Oceanic and Atmospheric Administration), US. Navy (United States Navy), NGA (National Geospatial-Intelligence Agency), GEBCO (General Bathymetric Chart of the Oceans), Image Landsat, and Image IBCAO (International Bathymetric Chart of the Arctic Ocean). Using random sampling of spatial area in Kigali per target area, 342,843 thousands images were retrieved under the five categories: residential high income (78941), residential low income(162501), residential middle income(101401), commercial building, (67400) and industrial zone,(24400). For the industrial zone, we also included some images from Nairobi, Kenya industrial spatial area. The average number of samples for a category is 86929. The size of the sample per category is proportional to the size of the spatial target area considered per category. Kigali is located at latitude:-1.985070 and longitude:-1.985070, coordinates. Nairobi is located at latitude:-1.286389 and longitude:36.817223, coordinates.

利用深度学习和卫星图像对东非城市规划的经济区域进行分类

在这项研究中，我们使用了来自许多不同来源的卫星图像的数据。下面我们描述和可视化正在考虑的数据集的各种指标。卫星图像检索自谷歌地球，由美国国家海洋和大气管理局(NOAA)和斯克里普斯海洋研究所(Data SIO)提供支持。海军(美国海军)，NGA(国家地理空间情报局)，GEBCO(海洋通用水深图)，图像陆地卫星和图像IBCAO(北冰洋国际水深图)。对基加利每个目标区域的空间面积进行随机抽样，共检索到高收入住宅(78941)、低收入住宅(162501)、中等收入住宅(101401)、商业建筑(67400)和工业区(24400)5类342,84.3万幅图像。对于工业区，我们还包括一些来自肯尼亚内罗毕工业空间区域的图像。一个类别的平均样本数为86929。每个类别的样本大小与每个类别所考虑的空间目标区域的大小成正比。基加利位于纬度:-1.985070，经度:-1.985070，坐标。内罗毕位于纬度:-1.286389，经度:36.817223，坐标。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
