title: A literary geography dataset of Nanjing poetries
title: 南京诗词文学地理数据集

description: Poetry is one of the important carrier of historical and cultural inheritance. Nanjing is one of the first national historical and cultural cities in China, known as the "capital of six Dynasties" and "capital of ten Dynasties", with a long history, deep cultural connotation. There are a large number of poems with Nanjing as the object of description. The abundant cultural and geographic information contained in Nanjing Poetry is of great significance to the study of its historical culture and literary geography. Based on the data sources of books such as Complete Poetry of the Tang, The Complete Ci-Poetry of the Song, A dictionary of poetry appreciation in Song, Ming and Qing Dynasties, and Nanjing poetry map, this paper selects Nanjing poems written from the Tang Dynasty to the Qing Dynasty to sort out and extract literature and geographic information such as the author's life, poetry genre, poetry theme, the place described, literary landscape and landscape elements. According to the information obtained, the geographic data set of Nanjing poetry literature is constructed. The data set can provide a data base for the study of historical culture and literary geography.

title: MuSyQ高分16米/10天NDVI植被指数产品 （2018-2020年中国01版）

description: Vegetation index (VI) is one of the most important parameters for vegetation remote sensing research and application. However, there are few standardized regional or global high-resolution VI products available now. Taking advantage of the high spatial and temporal resolution of Gaofen1 WFV sensor, MuSyQ NDVI product of 16m/10days resolution in China from 2018 to 2020 was generated using the vegetation index synthesis algorithm. This product can be used to monitor the canopy structural and phenological characteristics of vegetation in China, analyze the seasonal and interannual changes of biochemical and physicochemical parameters. It can provide reliable data for the analysis of vegetation change, the application of agriculture and forestry, and ecological environment monitoring in China.

title: A photomicrograph dataset of sand grains from the Yarlung Tsangpo, Tibet
title: 雅鲁藏布江砂粒显微图像数据集

description: Identification and statistics of reproduction of river sand and sediment components are the key steps of provenance analysis. The traditional human identification and manual statistics process are time-consuming and laborious, and the data obtained are of different standards and of uneven quality. The data obtained by different laboratories are of poor contrast. The automatic identification of sand components by computer using machine learning technology can help geologists relieve themselves from this tedious and time-consuming work. To achieve this goal, professional geologists need to take and mark a large number of microscopic image files as a basis for training. However, the large number of computer workers who want to do this work cannot find such datasets. Based on the principle of data disclosure and sharing, the author published the marked image dataset which had spent a lot of time and energy before. The dataset consists of 8,734 tagged clastic particle images and coordinate files, 1,536 sand microscope images, 120 numbered base maps and two sand composition identification tables, which provides a large number of data bases for computer automatic identification of sand components using machine learning techniques, and can also serve as reference standards for identification of other river sand detrital components.(Terms of data protection: 3 years. Sample URL: http://www.dx.doi.org/10.11922/sciencedb.j00001.00044)

title: A sandstone microscopical images dataset of He-8 Member of Upper Paleozoic in Northeast Ordos Basin
title: 鄂尔多斯盆地东北缘上古生界盒8段砂岩显微图像数据集

description: There are abundant natural gas resources in the upper Paleozoic in the northern Ordos Basin, and he 8 member is the main gas producing layer in Sulige gas field. However, at present, the related research of He 8 member mainly focuses on core, logging and seismic, and the fine study of outcrop of He 8 member is still rare, especially the systematic study of microscopic and microscopic characteristics of sandstone. Based on the field survey of outcrops in the periphery of Ordos Basin, the Tianshengqiao section in fugu, Yulin, which has the same provenance as the He8 member of Sulige gas field and has a relatively consistent sedimentary environment, is selected for field survey, description and intensive sampling. The rock types, structural characteristics, mineral composition, diagenesis and other aspects are systematically studied, and a complete sandstone microscopic image set is classified and sorted out It is expected to provide valuable basic data for the study of sandstone characteristics and controlling factors of high-quality reservoirs in the upper Paleozoic of the northern Ordos Basin.

description: Purple soil is a special species due to mode and speed of pedogenesis with world pedologists’ concerns. Its parent materials mainly include talus material, residual deposit, and weathered bedrock of purple sand shale formed in the Triassic, Jurassic, and Cretaceous systems. Purple soil has its color, physicochemical characteristics, and mineralogical composition derived from the parent materials. This dataset is a quarriable logical one, developed from the geochemical findings of purple rock and its weathered crust in the book of “Purple Soils in China (Part I)”. The dataset consists of 11 worksheets in 4 parts, i.e.: (1) general characteristics of parent materials and rock strata for purple soil, (2) purple rock types and their geochemical properties, (3) geochemical composition and characteristics of weathered purple rock crust, and (4) classification of the weathered purple rock crust and its diagnostic indicators in the Sichuan Basin of China. The dataset inherits and protects the historic findings in purple soil research and supports research and applications of soil fertility, ecological environment, and land resource utilization in the purple soil regions.

title: Population Density Data Set of China's Townships (subdistricts) (2010)
title: 中国乡镇（街道）人口密度数据集（2010年）

description: Township is so far the smallest unit for official demographic statistics in China. When correlated with administrative boundary, demographic data can be used to analyze the spatial distribution of population, which is significant for research on geography, resources, environment, ecology, disasters, sustainable development, etc. Based on the demographic data of the 31 provinces, municipalities and autonomous regions publicized by the National Bureau of Statistics in 2010, we correlated township administrative units with the number of population in each, while attending to spatial topological problems such as pattern spot gaps and overlaps between the spatial divisions. In total, 42122 spatial units were paired with their demographic data by using the decision tree. The average population density was calculated as the number of population per spatial unit, which was then converted into vector data for generating the dataset of township-level population density in China (2010). A validation of the data shows an overall accuracy of 99%, with a less than 10% deviation for each province or municipality. The dataset is in the TIFF format, with a total volume of 108 MB.
