资源简介:
In the context of the EU-funded project DIONE (No. 870378), VNIR topsoil reflectance was captured with DIONE’s Soil Scanning System and transformed through Machine Learning modelling to a set of soil properties that are meaningful for the assessment of soil health. The captured reflectance measurements correspond to locations distributed within the pilot areas of Cyprus and are indicated after the analysis of EO multispectral imagery, aiming to create a collection of point locations that well represent the soil characteristics of the area, and provide valuable information about soil condition through the estimations of the following soil properties: Sand % Clay % Silt % Electrical Conductivity (mS/m) pH Calcium carbonate % Soil Organic Carbon % The dataset is delivered in a shapefile format (DIONE_CY_point_estimations_2022_WP4.shp - EPSG:4326 - WGS 84) containing the following fields: Description of the information contained in the corresponding "CY points estimations" dataset Field Type Description Sample_ID String Unique ID Lat Real Latitude Lon Real Longitude Sand Real Sand fraction Clay Real Clay fraction Silt Real Silt fraction EC Real Electrical Conductivity ph_H20 Real pH CaCO3 Real Calcium Carbonate SOC Real Soil Organic Carbon

在欧盟资助的DIONE项目(编号870378)的研究框架内,研究人员借助DIONE土壤扫描系统采集了可见近红外(VNIR)表层土壤反射率数据,并通过机器学习建模将反射率数据转换为一系列可用于土壤健康评估的关键土壤属性。 本次采集的反射率测量点位均分布于塞浦路斯试点区域内,且通过分析地球观测(EO)多光谱影像筛选确定,旨在构建一套能够充分表征该区域土壤特征的点位集合,并通过估算以下土壤属性,为区域土壤状况研判提供宝贵的参考信息:砂粒占比(Sand %)、黏粒占比(Clay %)、粉粒占比(Silt %)、电导率(单位:mS/m)、pH值、碳酸钙占比(Calcium carbonate %)、土壤有机碳占比(Soil Organic Carbon %)。 本数据集以形状文件(shapefile)格式交付,文件名为DIONE_CY_point_estimations_2022_WP4.shp,坐标系为EPSG:4326 - WGS 84,包含以下字段: 对应"CY points estimations"数据集的信息说明如下: | 字段名 | 数据类型 | 字段说明 | | ---- | ---- | ---- | | Sample_ID | 字符串(String) | 唯一标识符 | | Lat | 实数(Real) | 纬度(Latitude) | | Lon | 实数(Real) | 经度(Longitude) | | Sand | 实数(Real) | 砂粒占比 | | Clay | 实数(Real) | 黏粒占比 | | Silt | 实数(Real) | 粉粒占比 | | EC | 实数(Real) | 电导率 | | ph_H20 | 实数(Real) | 水浸法pH值 | | CaCO3 | 实数(Real) | 碳酸钙占比 | | SOC | 实数(Real) | 土壤有机碳占比
