Landsat8 Image Training Data Set of Grassland Types in Tarbagatay Prefecture in 2023

Grassland resources are the material basis of animal husbandry production and the gene pool of biodiversity, which have the ecological functions of preventing wind, fixing sand and conserving water. Grassland classification based on satellite remote sensing can not only provide data support for the investigation of grassland resources, but also provide a basis for the study of grassland species diversity. Based on the field survey data, the grassland classification information of real sample plots was obtained. By using the preprocessed Landsat8 remote sensing images such as radiometric calibration, atmospheric correction and image fusion, and by means of visual interpretation,3360 multi-spectral remote sensing image classification training data sets of 8 types of grassland in Tarbagatay Prefecture area were constructed by using ArcGIS software. This data set can not only provide data basis for remote sensing image classification of grassland in Tarbagatay Prefecture, but also provide data reference for researchers in related fields in other areas.

草原资源是畜牧业生产的物质基础，亦是生物多样性的基因库，具备防风固沙、涵养水源的生态功能。基于卫星遥感的草原分类，既可为草原资源调查提供数据支撑，也可为草原物种多样性研究提供依据。本数据集依托野外调查数据，获取了真实样地的草原分类信息。通过对经过辐射定标、大气校正、图像融合等预处理的陆地卫星8号（Landsat8）遥感影像进行目视解译，并借助ArcGIS软件，构建了塔尔巴哈台地区8类草原共计3360景多光谱遥感影像分类训练数据集。该数据集既可作为塔尔巴哈台地区草原遥感影像分类的数据基础，也可为其他地区相关领域的科研人员提供数据参考。
