Proximal soil sensing data from the RapidMapper, a novel mobile multi-sensor platform for topsoil mapping [Booßen (Brandenburg, Germany), August 2021].

Proximal soil sensing data were collected by a novel multi-sensor platform (“RapidMapper”) for on-the-go topsoil mapping. This platform was developed within the BonaRes project “I4S (Intelligence for Soil) – Integrated System for Site-Specific Soil Fertility Management” (https://www.bonares.de/i4s). The sensor data comprise: (i) apparent electrical conductivity (ECa) using the galvanic contact resistivity technique based on the Wenner array configuration, (ii) near-infrared (NIR) spectra covering the nominal range of 8602550 nm with a resolution of 1 nm (C11118GA, Hamamatsu Photonics K. K., Shizuoka Pref., Japan), and (iii) gamma spectra from a CsI (Caesium Iodide) scintillator crystal (MS-2000-CsI-MTS, Medusa Radiometrics BV, Groningen, Netherlands)detecting the naturally occurring radionuclides, Potassium-40 (40K), Uranium-238 (238U), Thorium-232 (232Th) and Caesium-137 (137Cs). They were collected from the topsoil at a measurement frequency of 1 Hz during a field mapping campaign in August 2021 conducted on an agricultural field of 15.5 ha in Booßen near Frankfurt/Oder (Brandenburg, Germany; 52°23’38.688’’N, 14°27’38.844’’E). The RapidMapper platform was pulled over the field at an average speed of 2.5 km/h and along parallel tracks being about 18 m apart.

本数据集采用新型多传感器平台"RapidMapper"采集行进式表土测绘所需的近地土壤传感（proximal soil sensing）数据。该平台由BonaRes项目下的"I4S（Intelligence for Soil – 智能土壤——农田精准土壤肥力管理集成系统）"研发，项目网址为https://www.bonares.de/i4s。所采集的传感器数据包含三类：（i）基于温纳（Wenner）阵列构型的接触式电阻率技术获取的表观电导率（apparent electrical conductivity, ECa）；（ii）标称波长范围860–2550 nm、分辨率1 nm的近红外（near-infrared, NIR）光谱，设备型号为C11118GA，制造商为日本静冈县滨松光子株式会社（Hamamatsu Photonics K. K.）；（iii）由碘化铯（Caesium Iodide, CsI）闪烁晶体传感器MS-2000-CsI-MTS采集的γ射线光谱，该设备由荷兰格罗宁根市Medusa Radiometrics BV制造，可检测天然放射性核素钾-40（⁴⁰K）、铀-238（²³⁸U）、钍-232（²³²Th）以及铯-137（¹³⁷Cs）。
数据采集于2021年8月在德国勃兰登堡州奥得河畔法兰克福附近布森镇的一块15.5公顷农田开展的田间测绘作业中，以1 Hz的测量频率采集表层土壤数据，对应坐标为北纬52°23′38.688″、东经14°27′38.844″。采集过程中，RapidMapper平台以平均2.5 km/h的速度被牵引驶过田块，轨迹为间距约18 m的平行测线。
